Tech Tips – Residential IHT (w/ External Expansion Tank) Oil Maintenance

Oil Maintenance Procedures for Residential IHT units with External Expansion Tank
Designed to be trouble-free
Normally the Residential IHT (K46), which is featured in many tractor & rider models, does not require any servicing for the life of the vehicle. However, if there is a desire to check or replace oil, it may be necessary to remove the transaxle from the vehicle to access the black cap located under the pulley and fan. Due to the design of our units.
Maintenance Overview
First, remove the transaxle from the vehicle following OEM instructions. After placing the transaxle on a bench surface remove the fan & pulley and pry open the black cap and remove magnet (see Fig #1). Invert transaxle to allow the oil to drain from case through the port under the black cap.

Tuff Torq K46 Oil Maintenance – Figure 1
Refill transmission case with oil through same port to near top of the case. Tuff Torq® recommends refilling transmission with Tuff Torq® hydrostatic oil, available from our service and aftermarket department.
Reinstall magnet & cap. While reinstalling the fan & pulley on drive shaft be sure to place all components in the same order as they were removed.
In heavy usage applications, oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter. The filter should never require changing unless the transaxle is removed from the tractor or rider and opened for repairs.
Finally, after purging the transaxle of air, add additional oil through tank opening (under vent valve) to the recommended oil level. (see Figure #2 below for recommended oil level).

Hi again. Since my comment I’ve found that the input pulley and input spline are stripped. Label reads Tuff Torq 7A646084030 S/N 46A10004335. Can you advise an agent to supply parts? Thanks.
Hi, I have a Seco Starjet AJ102/15,5 01 mower. That suddenly lost drive. fan and pulley on top spin but just a rattling noise instead of movement. Any suggestion of a fix and service a agent in New Zealand? Thanks

The speed on my K46 is great in reverse but in forward it is much slower. Any thoughts? It has been slowing for some time and gets worse as the machine warms up. New drive belt has not solved the issue.

Needing to rebuild or replace transaxle on John Deere LT180. Having trouble identifying the correct unit. Tag on axle says:
HOP PN: 426120
Tuff Torq 7A646084181
SN: 46BT0774054
When I search on this info it seems this is for a Craftsman unit. Can you help clarify?
Need help troubleshooting K46BA transmission. Control level forward or backwards, no motion. Drive belt in great condition, tight and turns while motor running. What is not working properly? Any help would be greatly appreciated.
I have a John Deere 345 with K70 transmission. John Deere says to use low vis hydraulic oil but your chart shows 10 W 30 motor oil. which is the better choice?
My TUFF TORQ transaxle tag is 7A646084180, s/n 46BT0315800 ,HOP PN 405384. My parts manual list transaxle as PT#532 40 53-84. I find on the web the substitute part number is now 532 42 6120. My wheel axle is broke into. Is the part number 532 42 6120 the correct part number for me to order?
I can’t buy from that site. because it is in the States and I am in British Columbia Canada. Do you have any outlets that I can buy Tuff Tech Oil from in Canada? Thanks ~~ Dan
Cub cadet LTX1046KW with 520 hours, used to cut manicured centipede, Suggested fluid change? Having no problems.
I see online that a lot of people are using 5W50 full synthetic oil, is that a good oil to use? My Transaxle no.s are. Tuff Torq 7a646084321 — S/N 46cr0120448 — HOP PN: 426121 I thank you for your help in this matter. ~~ Dan
We are in southern BC and do not get as cold as farther north does. The noise happens all the time, summer and winter. I let it run with the brake off for a couple of minutes to warm up the oil, it still does it but not quite as bad as when I first start it up. I also have a snowblower that I use on it with Chains and wheel weights on the rear tires with a counterweight on the rear. So I do use it in cold weather but the noise is not any worse once it warms up.
I have a Husqvarna yt42xls with the k46 transmision. 5 years old with 256 hrs on it. Cold the transmision whines badly, gets less noisy as it warms up but is still loud. Pulls ok all the time either cold or hot. Should I be concerned with the noise? Thank you Dan
There is a clunking noise in forward drive in my John Deere D-160 but not in reverse drive. It has just 88 hours total time.
Any guess as to the problem?
I have a Husqvarna YTH2348 W/ a K46 Transmission ans I need a rebuild kit for the hydralics in the transmission. You asked me to get the transmission numbers off of it. they are: Tuff Torq 7A646084181 followed by the serial number: S/N 46BT0523468. there is also a HOP PN # of: HOP PN 426120
I HAVE A CRAFTMAN YT 3000 AN LOOKING TO CHANGE THE TRANSAXLE FLUID, BUT NOT SURE WHAT TYPE OF OIL AND WEIGHT TO USE. DO I USE A SYNTHETIC MOTOR OIL OR A HYDROSTATIC TRANSMISSION FLUID?
When servicing by transmissions 7A646084460 on my riding lawnmower I am at the point of removing the black cap to drain and refill. I am having quite a time prying that cap off the transmissions. Any recommendations?
I have an 8 year old Cub Cadet LTX1046WK with a TUFF TORQ 7A646084460, S/N 46CA0013939. The reverse is very slow and now the transmission is noisy and slipping. Is all that is required a fluid change. Also, not sure what is meant by an air purge when doing a fluid change?
Hello, I have a Husqvarna YTH2348 with a K46xx transmission with over 700 hours. Mowing fine today, uphill and level. Had a few hard jerks, then stopped moving altogether, both forward and reverse. any thoughts?
Good day, I have a Husqvarna YT48XLS Model# 96043015500 with a K46 CR/LD transaxle. When it is cold, it will climb hills fine, but after it warms up, it will not climb anymore. Level ground is fine. I’ve never changed the transaxle fluid. Do I need a new transaxle or is there hope for just a fluid change? I have no leaks, and no other issues
Hello, I’m repairing a K46AC S/N:46ACC0100281 and I’m looking for repair parts delaers in Guadalajara, Jalisco, Mexico.
Also want to know alternatives to the OEM fluid and fluid capacity. Thanks in advance.
I own a Husqvarna YTH2348 w/a K46 transmission. Last year I noticed that after it getting warm, it started sounding like a bad power steering pump and I figured I’d change the fluid, but to no avail. when it heats up (I am mowing a very hilly property) it loses it ability to climb. I was wondering if there’s a pump assembly or something to rebuild/replace? When it’s cold while it’s loud it works fine. after about 20 minutes it won’t climb. level ground it’s okay. any suggestions on what I can do?
Hi I have owned an LTR180 from new 2005 yesterday it stopped driving and it looks like the drive pulleys have collapsed. The machine is for home use and has not been worked hard, I have taken it my John Deere dealer for repair, I will ask them to change the oil, do I need to go any further than that, internal filter and so on?.
Thanks Steve
Hi just bought a 2020 jd e170 an I have read a bunch about the k46iht an was wondering how durable they are. Mine has the k46be iht any info would appreciated
I have an LTR180 Deere, k46a trans S/N 0037761complete loss of drive. at first struggled on hills not just get a slight movement going back or forward.
On inspection of disassembled trans some slight chipping on spider gears not a lot of metal on magnets. had a paper filter (new replacements I see are screens) Is it possibly just a dirty filter? all plungers in pump and motor seam tight no lateral play noticeable. since apart I was going to replace gears & new screen. pump and motor are fairly pricey if they look fine should I need to replace these assembly’s?
and if there is some wear to these assembly’s would a nice heavier synthetic be advised?
Diagram and instructions very helpful thank you Tuff Torq.
Good morning I have a Husqvarna 24hp 54 p. Cut. Replace the entire transmission for loss of strength.
I need to know what oil to use in the new box since the one recommended by you is not available in Argentina. This machine is for intensive use and slopes. Thank you
My mower runs great till it warms up it gets slower and slower till it stops it is a craftsman Tuff Torq 7a632084620 S/N 66y-0009465 Hop PN 199973 this is not the first one that heard of that went bad could it be oil your is it likely in the pumps.
Got a 2015 craftsman t.t. 7a646084590.
S/n 46dm0181550
Mtd p/n 618-06972
Has 76 total hours on unit has hydraulic whine and peeformance deteriorates as warms up. Do i probably need overhaul or should fluid and filter do the trick.
when I use a lift to raise the front end of my riding mower [k46 transmission] oil drips onto the floor. I know it’s from the transmission. can this be some kind of failure of the vent valve and cap? I had to add a good quart of oil to the trannie when I lowered the machine and it did not move at all.
After changing the oil with 5-40’s synthetic and cleaning the box my K46F runs a lot quicker in reverse than forward although I am convinced I replaced the tapered plate which fits onto the piston unit and alters the direction. Do I need to open up the box and refit the tapered plate.
Regards
Nigel
Two #s. 618-04270B or 103EH3D276 hydro-Gear. What oil and best way to drain it . To bad no recall on them.

I have a 2011 cadet slots 1050 mod #13wq92apo010 s/#1b231h60046 drive belt replaced will not go up incline in reverse is the recommended oil 20w50 oil motor oil or hydro oil appreciate any help.
I have a cub cadet xt2. The turning radius is listed as 18″, but I have trouble try to turn at twice that radius. The back tires dont seems to have a differential gear and just push the front tires straight ahead. Is there something wrong with the transmission?
I have a YTH24V48 I just bought. I doubt if the fluid has ever been changed. It has 187 hours. I would like to put 5W50 in it. What can I expect to pay at the dealer to have this done? I believe this is a 2013. I have the model and serial number but can’t seem to find the info. Product # is 960450046. Serial is 012814A010040.
Can I use aw32 hydraulic oil in my transaxle transmission instead of Tuff Torq k46 oil?

Hi there, I have read your negative comments regarding the Tuff Torq transaxle and all the problems and repairs carried out. All I can advise is to try out some new Pullyes! Ypu’d mentioned an oil-change and also that the drivebelt had been replaced. If 100% properly purged (sounds simple but actually isn’t), well then if now power it can in my humble opinion still be a drivebelt issue. How to check this? After running it and noticing the slipping, stop the engine and get off, check directly by touching the drive pulley on the engine and over the drive axle. If these are warm or even hot, well then check by looking at the pulleys exactly where the belt runs. If all shiny well then the slipping is obvious and the heat confirms this. Then and although you’d previously invested in a new drivebelt you still have slip!
how much does the k46 hold for oil with out the extra tank
Hi Guys I have a K46f transmission but the pistons have started to stick. Have tried to order a replacement cylinder block 168T2025090 but the part appears to be unavailable in France. Can you advise me if it is possible to order a part or even the pistons and springs
I sure learned a lot after reading the article. Many thanks.
Hola buenos dias tengo mi k46 que no luego de calentarse no avanza ya cambie el aceite como me recomendaron y no hubo mejoras debo reemplazar las partes hidrulicas me pasaria el pdf de las partes por favor gracias
Would like to upgrade transmission on JD e140 Tuff tourq 787T0124010 SN AAK00006736 as there are no level areas in my yard What is available direct fit no mods with locking differential ,and at what price .
K51a trans what oil and how much does it Hold
I dont fully understand the oil level.
Just fill until it is 4.5mm from the top? Seems like a lot of oil
I have a Westwood S1300 approx 2009 with a K46 transmission, after about 1 hour of mowing it loses drive going uphill, it is ok on the flat. Do I need to just change the oil, if so do Ii need to remove the transmission or can I draw the old oil from the reservoir tank.
I have a K46 in my 2014 cub cadet is there a way I can beef up my trans for mowing hills? Gets hot after ahwile for mowing so much just changed fluid out
I have a leak in my JD L120 K46 transmission coming from the left rear bolt. I discovered a trail of oil up the drive and into the garage with a fairly large amount of oil in the garage. The apparent amount of spill would appear to be more than what is leaking from the bolt. I don’t see any evidence that the oil spilled down from the top of the trans yet it seems impossible that much oil could have come out through that slowly dripping bolt? The bolt was tight. What might cause this situation? What is the likely hood that the internals are damaged and a full rebuild is necessary?
What are the thread/specs of the 114 fan bolt on the k46ca? Part# TT-1A646083090. Could it be replaced at a big box stores or is OEM necessary?
Cub Cadet Model #13W1A4CA010. Loss of power up hills. Axle seal was bad, leaked all the trans fluid out. replaced the seal, used 15W-40 motorcycle oil to replenish, better power now, but still hesitates. am I better off rebuilding the trans or is there another trick I could try? If recommended to rebuild, where could I purchase the rebuild kit. This Transmission is K46 ETC. Also, the mower had ran for quit some time before the notice of any power loss. at one point, the mower stopped moving forcing me to troubleshoot and repair. Also, when i went in to fill the fluid, had to replace the fan as there were no blades on it (who knows how many hours of operation under this condition). Thinking the trans overheated, blew the axle seal, leaked out the fuid, (because i was stupid and didn’t notice) continued using all up until it totally stopped moving.
I have Model # 40A-01250943 in a JD L108. Its starting to whine. Want to change the fluid. Is this the K46 trans, and what fluid (vicosity) does it take?
Thanks.
I have a Cub Cadet LT46 with k46 drive in it. I can cut for about an hour and after that it quits moving. Any info would be great on this. Just oil change or rebuild? I am leaning towards an oil change cause when it does pull it pull great with no issues. I have cleaned all debris from around it to make sure it’s breathing good. Fan on top is also good.
I have a John Deere L130 with 7A646024390 Hydro. It will not climb inclines anymore. Is rebuilding it ok or will I run into the same issues. What options are available ? This tractor still has strong motor and deck.
Thanks Jim
Hi,
I have a 7A646024041 which has a small leak from the right shaft. Just wanted to confirm it is just the seal that is likely require repair (Seal 19*32*8) and if this can be replaced without breaking the unit down? Also it barely moves when under load after being used for a half hour. Replacement oil?
Thanks
Thanks for your reply Graham have opened the box and found 3 pistons ceased so have ordered a new cylinder

I want to remove the KK46BR-JOHN DEERE / 7A646084220 on my 2008 JD X300 to change the oil. It may be sluggish on hills but otherwise this is preventative maint. and the first maint for the K46. I have no leaks or other issues other than sluggish on hills. Is it worth me splitting the case for inspection and cleaning magnets or am I better just to get the TT3 in it and leave well enough alone? Hour meter is @ 261
I recently topped up the transmission Oil on my WESTWOOD T1800 TUFF TORQUE K46 HYDROSTATIC Transmission.unit
I think I may have overdone the volume because since the top up I have oil leaking from the transmission on the garage floor which appears to be coming from the bottom of the transmission unit particularly after use . Should I be concerned I have caused any damage or. should I let I simply continue until it reaches a level where it not overfilled …thanks for your help
I HAVE A LGT 2654 HAVING TROUBLE GOING UP HILLS. DRIVE UNIT 7A646084091
I have a Husqvarna LGT2654 with drive unit 7A646084091 that is leaking oil at the control shaft seal. Is a replacement seal available? If so, what is the part number?
Thanks in advance for your help.
Hi GGraham sorry but have a problem with my K46F drive unit After breaking down the box and inspecting all parts cleaned everything and filled with new oil. My test drive was ok for 10 mins but felt as though the IDS was jerky then all drive stopped both forward and reverse. Your previous advice was to replace the input drive shaft I have not done this as it seemed ok but will if necessary. I will breakdown the box tomorrow but would be greatfull for any advice. Regards Nigel
I am trying to purchase the spline shaft for a John Deere LT 155, 38″ deck, MOL155B025410. I am assuming I will need to flush and replace the filter. I had trouble trying to log in.
I bought my tuff torq last year. It did good for the first year. this year It started cutting grass foreword and reverse no problem. then It quit,will not go in any direction. what is my problem? I probably put 12 hours on it last year.
My tuff torq stopped moving. When I removed the transmission and drained the oil it was milky. Would that cause the transmission to malfunction?
The thin metal pipe extending approx 2″ from the external reservoir down to my K46 is free to slide in and out of the transmission casing, and leaks. the larger diameter connection also leaks. Can you advise on the failure and the remedy for both these leaks, please.
Thanks GGraham
Nigel
Hi guys
Could you let me have the part no for the modification to be fitted to my K46F. The mod is a flat bracket fitted with 2 extra magnets and is fitted on top of the drive / pump unit with 2 of the existing 3 bolts

Hello I have a k46. I had a Bearing that broke and replaced and changed oil. And only works for 5 minutes. I dumped oil out and refilled it and only runs for 5 minutes can you help
Bonjour,
J’ai vidangé ma boite k46h par les 2 vis de purge situées dessous. J’ai refait le plein par le réservoir externe. La partie Gear est remplie mais la partie hydro ne se remplit pas.
Faut-il remplir par le capuchon noir ? Si oui, quel est le niveau recommandé pour une boite avec réservoir externe. Je pense qu’il faut remplir au maximum pour que l’huile coïncide avec la partie Gear.
Dans l’attente de votre aide. Merci d’avance.
Thanks GGraham for your reply do you have any info, parts list to help me with my limited experience in opening up the unit any advice gratefully accepted.

Hi guys
My honda 2417 hme mower (2006) is fitted with a Turf Torq unit 7A546024051 with external oil tank and s/n 46F 019174
My problem is grinding noise from the unit so could not find the drain plug but managed to get some of the old oil out and replaced with 30/50 multigrade engine oil as no hydrostatic oil available. The mower still grinds in forward and will not go uphill but not bad on flat ground, in reverse the mower grinds occasionally but climbs uphill no problem. Could you suggest a solution
Regards
Nigel Teale
Has anyone tried washing out the K46 with gasoline to get more of the old oil and metal residue out?
Is that a good idea or not?
Hello,
I have a k46; is there a torque setting for the bolts that hold the bottom sump on. My bolts were loosened with the intent to drop the sump but this was not required so the sump was not removed or the seal broken.
is the magnet that goes under fill cap available by itself–I’m changing oil an mine is broken in pieces–k46 transaxle
In a K46 rear end you are saying to refill with 5w50 synthetic, right? Could you at lucas oil stabilize as well? Also have automatic hydrostatic oil 56 would this be any better to help the rear end from heating up?
I have a k46. I had to cut out the fill cap to remove it . I see there is a steel cap. Would that replace the rubber one?
I have a K46 in a D130 that is gets hot and slows down and blowing oil out the fill plug what can cause this
I replaced the original k46 transmission in my x300 which wouldn’t move once it warmed up with a new replacement k46br from john deere. I now have 15 hours on the new transmission, how often should I change the oil in it so it doesn’t do the same as the first one? What is the best way to drain the oil out and where do I get new oil for it?
Why does tuff torq recommend 5w50 over the original 10w30 for most applications? That is a significant viscosity change, I could understand switching from the original 10w30 conventional to synthetic 10w30. But why to 5w50? Thanks for your time.
I have a K46 transmission (I believe) without reservoir that is in my John Deere L130 S/N GXL130A117878. I know it should take 2.4 its, but how high after purging air should i have the level? Up to where the magnet sets so once it heats up it runs past or all the way to the top with magnet installed? Thank you!
what is best way to purge a K46DM on a cub cadet?
Hi there, is it possible to reinstall the same cap after removing? I removed the upper plug and drained mine after I had a main drive gear failure. I’m about to install it and reassemble my mower, thanks in advance
I have a husqvarna yth24v42ls and I recently noticed the k46cr to be leaking fluid. Is it possible that changing the fluid would resolve the issue? Thanks so much.
Have a great day.
I have a k46v how much oil it take to fill
what is the total amount of hydrostatic oil do fill a tuff torq K46 transmission?
If the Tuff-Torq 918-07009 rear end is completely empty how much fluid should it take to fill it ?
ive got a tuff torq 46c the only thing i see is a side screw port is this where i check the fluid level and also fill it also axle seal is leaking how do i get it out and install new one do i need to remove axle and split it thanks very much for any accurate advice
I have a 2016 Cub Cadet XT2 Enduro Series GX54 (26 hp Kohler/54″deck). It just started leaking oil from the left rear wheel seal area. I thought about replacing the seal and have been advised there is a cap on the top side under the seat/battery area to top off the oil. I have not checked this yet but if so, what would be the best oil (10w40?) to use to top off? Thanks a lot!

Hi, My K46 is still jerking for about 5-10 minutes from cold, after which it is fine. If I pre-heat the gearbox to say 85F, it runs fine out of the garage.As the oil has been changed for a 5W-30 does this suggest that there is internal damage? Thank you.

Dear Sirs, I have a 2554 Husqvarna lawn tractor. I had a problem with it when it gets warmed up it doesn”t want to go up hills. I took the transaxle out and disassembled it. the only thing I seen any wear was the springs in the motor and pump. All pistons and cylinders looked very clean with almost play or wear on the chrome of the pistons. I replaced the springs with new ones, put it back together. and it goes forward in reverse. and backs up in forward. Can you tell me what I may have done to cause this? Should I have replaced the pump and motor?
Hi, Recently (for the 2nd time) the left rear axle on my Craftsman mower broke at the point it enters the transaxle housing. I mow about 1 acre on flat ground and am wondering if this is a weak point on the axle. This K46 is about 6 years old – the first one was about 3 years old when it broke. The first time the dealer sold me a new transaxle and what I have for numbers are K46BN 7A646084160 468N0046861 – The numbers are coming from my paperwork because the units do not have the sticker on them. I kept the original transaxle and am debating on attempting to just replace the broken axle or replacing the mower. If I opt to repair either or both units is that doable for someone with fairly good mechanical abilities or does it get technical? Also are there repair parts available?
Thank you for your time……..
HI, I’m looking for a specification of the transmission my CastelGarden tuff torq PIN 18400965 s/n 7A646024410 46T 0644136.
I appreciate if U would help me in.
My K46 has started hesitating/slipping and growling when cold, forward or reverse. Cold here is say 5 celcius. After about 10 minutes of use, I get full power no problem. In the summer it’s fine all the time. Belts , pulleys and linkages are good.
I topped up the oil last year and it seemed better, but it seems much worse this winter.
Any ideas?
Thank you
What replacement sizes will bolt up to the husqvarna LGT2654. Came installed with the k46.

HELLO!
I have a 2018 John Deere E140 with K46.
If I press the foreward pedal harder I go faster. If I press less I go slower.
Am I riding a clutch to go slower ? Will this damage the K46 ?
Should I always press the foreward pedal fully ?

Hi, will any k46 fit a John Deere Lt180
Sorry, one more thing. I assume the transaxle is a K46.
I have a Tuff Torq transaxle and the following information is listed on its ID tag:
TUFF TORQ 7A646084321
S/N: 46CR0090284
HOP PN: 426121
I obtained it from an older gentleman who liked working on lawn and garden equipment. For health reasons, he reluctantly had to stop. He had this transaxle, but couldn’t remember what model or brand of equipment it fit. Very clean unit. Drained the oil (only 1/2 quart approximately) but it was pretty clean and contained no metallic particles. Magnet under fill plug had a slight grey film – appeared to be from normal wear and tear. If you could tell me what equipment it would fit and whether or not it appears to be ok based on the oil and magnetic observations, it would be much appreciated. Thank you.
Will k46 hydrostatica axle work in a L LT155 deere
I re did the seals in my tuff torq k46s transmission. Now when I press the forward pedal it goes backwards and the reverse petal it goes forwards. Anyone come across this before?
Hello, changing my fluid, can you tell me the capacity for my k46 please.
7a646084321. S/n 46cr0078626. Thank you!
Hi I have a k46 bt what is the adjuster and lock nut on the right side for and how to set it. How much oil does it take.
Hello. I have a k46bn on my husqvarna gth2654, i recently broke the left axle somehow and i am trying to figure out what axle repair kit i need for this transmission. Thank you
Hi. I have a countax with a K46E .
On start up the mower will not move but if you give it a push and drive it for 50 yards it is then fine..
The mower is 15 years old and had moderate use
Can you help?
Can I use 15w-50 in the transmission. I have 3 quarts of it already.
Sorry one more question…. The sticker on my JD D160 K46 says 7A646084121. Can you tell me the oil capacity?
How can you “purge the air” with the transaxle on the bench? I’ve read the procedure to do it with the transaxle installed, but on a John Deere D160, I’d then have to pull it back out to top off the oil since there is no access to the top of the transaxle.
Also transmission has to come out doesn’t it?
I have an lt 166 j.d. and have noticed a little oil on the back of the gas tank. I’m guessing it’s from the transmission and seems like it’s lost a Little pulling power. Do you have an idea on fluid capacity and fluid type? Any help would be appreciated
We have a Cub Cadet ride on the mower will work for awhile then starts slowing down going up hill. Oil was never changed in it. Can it be low on oil or has the oil broken down so badly it has ruined the transmission? There is 220 hrs on the machine but we cut hilly terrain . Thanks Glenn.
Pulled transmission apart changed oil put back together/ now mower goes forward on reverse pedal and forward on reverse pedal, what hav we done wrong.
I have been readng all of the Q & A and will be draining the trasmission and changing the oil and am considering adding Lucas transmission additve. I would appreciate your input on this.
Husqvarna YTH24K48 I understand it uses a K46BT transaxle. When stepping on peddle for forward motion there is a long delay, tractor starts to move slowly until getting to normal speed. If stopped it restarts just as slowly. In reverse no dely at all. Engine runs fine, rpms remain constant. 144 hrs on tractor about 5 years old
Hello I have a K46A transaxle and I took it off the unit as it would run for 20 minutes and then stop moving. I let it rest for 20 minutes after the oil cooled down and then the unit would run for another 20 minutes. I just saw a video that showed how to drain the oil from it and noticed that there was hardly any oil in the unit, and whatever I was adding thru the air vent would come out after it heated up. Could it just be that I need to add oil to the unit and put it back together instead of rebuilding it? The unit does not whine or make noises when it moves but after 20 minutes it stops. Thanks for your advice!
1870 Christopher Trace Is the center section on a John Deere what makes in go in forward and reverse ?
Will 20w50 work in a k46
Hi,
I have a K46BE in my JD L130. I changed the filter and oil using Tuff Tech recommended oil. The trans drive belt started to slip badly. I replaced the belt and much improvement. But, it still slips going up a grade, even with a helper spring on the tensioner. Do I need to go to a lighter weight oil? I read that JD uses 30 weight.
I HAVE A TUFF TORQ K46DM HAS RED FLUID LEAKING FROM BOTH AXELS. JUST WONDERING WHAT TYPE OF FLUID SHOULD BE IN THIS? This tractor is 2015 with 90 hours on it… not sure if I should change the seals or the fluid?
What about the second black cap that is not under the cooling fan assembly. Do I drain that as well and what type and how much fluid goes back in the unit?
Thank you, ggraham. I will save this information. My searches today suggest going stronger may be more important than just pursuing a locking option.
I found a reference to updating the K46 with K57 internals. Do you have any knowledge of this?
I forgot to add the K62 is available on this tractor as an option with the large deck. The linkage could possibly be sourced from Cub Cadet.
Thanks.
Greetings. My 2018 Cub Cadet XT2 came with a K46 transmission. Due to the terrain on my property I am compelled to use tire chains even in good weather. Is there a transmission (K 62 perhaps?) with a locker option that I can swap in easily?
Hello. My husqvarna k46 is not driving. I noticed that a rear tire has bluish oil all over it. I believe an axle seal is blown and lost oil from here. Do I need to open the transmission to replace this or does it seat itself from the outside? Also I read about using 5w50 syn. Oil. Does this seem correct.
Thank you
I have a Craftsman Garden Tractor. It works fine for the last 10 seasons. It started to stop and transaxle winning before it climbed the hill but it cut grasses fine in flat area in 11st season. I removed the transaxle from the tractor today. This is the info from the transaxle:
TUFF TORQ 7A632084620 S/N: 66Y – 0002589
HOP PN: 199973
The reservoir has only small oil left in the tank. However, I have not drain the oil from the transaxle yet. There is no leak (as far as I can see from the housing. I would like to change and refill the transaxle fluid. What type of fluid it uses and how much? The reservoir has marks and show the level of fluid. However, there is no dip stick on the transaxle housing. How do I know that it is the right amount of fluid?
I will greatly appreciate any info that you can provide.
Best regards,
this Transaxle is loosing oil by spacer split how to stop it or how can i find a Transaxle
I followed your instructions for oil change and bleeding air.
I have a Husqvarna YTH24V48LS
Refilled with 10W50 synthetic oil but now it loses all drive after approx an hours operation.
Any suggestions?
I just received my new transmission and noticed it was full of oil. Do I have to drain the oil out and put new oil in or is it good to go?
My LTX1045 is leaking oil from the vent valve. I have added oil to the transmission several times and it continues to lead from the vent valve. I do have 125 hrs on it. How do I eliminate this problem?
2004 LTR180 with K46A external expansion tank. How do I check the trans oil level? Can I simply top up the oil in the expansion tank to keep the trans oil level at the correct level or or I have to add oil in the oil port under the fan?
hola tengo una husqvarna con k46 y el problema en esta es que después de 20 minutos de trabajo pierde toda la fuerza y ya cambie el aceite y el problema persiste 🙁 ¿que es lo que estara pasando?

I have a 2007 Craftsman MTS 5500 tractor with a K46 transmission. The number on the axle appears to be 7A646084161 SN#468N806013. The transmission quit working while vaccuming leaves and going up a small grade. It has some power going on level ground but will not climb a hill. The case is clean as there are no signs of oil leaking. What should I be looking for?
How much fluid does the K46 tranny hold?
do you offer a k46 with drain plugs?for a deere L120
Thanks for sharing the information. i really enjoyed your blog article. and you’r writing a good point.
Hi Guys,
I have an L110 John Deere and had a leaking seal on the input shaft . I removed the trans-axle and brought it to my local dealer for replacement. After installing it there is no grunt in the machine. It cannot even climb a small hill. I removed it again and found the oil level a bit low so I topped it up with about a cup of suitable oil. Could this be the problem, ie. low oil? If I need to rebuild the pump assembly/motor can you supply a rebuild kit? I am in Australia and find the John Deere people here only want to sell a complete trans-axle.
i like your page but dont go far enough some these tractors work all year round so the oil spec declare what type of oil
Good evening. I own a John Deere L130 lawn tractor. Manufactured date 05/12. It doesn’t move at all. Raised rear wheels off ground tires do turn slowly,but I can stop simply by touching wheel. I understand their maybe a problem with K46 trans. What is my best option for the money to repair or replace.
I have a craftsman riding mower model 917 288561 with 150 hrs. The k46 transaxle went out and have a new one coming soon.Do i need to purge it after installing and do oil changes every 200 hrs. or so with 5w50 synthetic.I mow normal with it at home but yard has some hills and is sloped for the most part.
I just inherited an 02 John Deere LTR 180 with a tuff torq K46 transaxle. Everything is working fine but there is a little humming noise when I engage the transaxle. The article above seems to contradict itself in regards to an oil change. First paragraph says “Normally the Strider™ transaxle (K46), that is featured in many tractor & rider models, does not require any servicing for the life of the vehicle.” Then “In heavy usage applications oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter.” What is “heavy usage?” and should I take the transaxle out and change the fluid? Thank you so much!
I have a 11 yr. old, 400 hrs. K46 in John Deere LT160, should I remove it and change fluid and was told to use 5w50 synthetic motor oil if I do !!

I’ll bookmark your blog and test again right here regularly.
I’m rather certain I’ll be told plenty of new stuff right here!
Good luck for the next!
Is there an upgrade kit for the k46 transaxle? I plan on buying a Cub Cadet LT with a 42″ wide mower deck. I plan on using it to mow and pull a 15gal. trailer type sprayer. Will the K46 ever need servicing if I use it as stated? If there is an upgrade kit, what does it consist of and what is the cost?
I own the John Deere L-120 and the transmission has failed. Imagine that? Any design that requires you to have to remove the transmission to replace the fluid is pure BS. The John Deere Manual says, “The transmission is a sealed unit that requires no maintenance” To add insult to injury they want to charge me more for a replacement than the mower is worth, knowing it won’t last either? Last John Deere anything I will ever own.
hai dear,which oil using K46 gear box.(grade) .equipment using in gulf contry.
Gentelmen…good mornin…heres the prob.John Deere l 118 2006 year mod…..mower working fine…needed to replace cooling fan…so i did according to procedure…mission acomplished…hoped on mower , and now no forward or reverse…replaced drive belt and drive idler ,and tension pulley asembley….no change…Now i did jack up and purge system and got slight movement but no torque…pullin my hair out in Texas…!!!!!!
I am having problems with my John Deere L130 tractor transmission slipping. Belt and pulleys are new. My tractor is a 2004 and is in very good condition. If I remove the transmission and change the oil can I drain most of the old oil from the top plug. I have observed someone trying to suck out the oil but he only got about a pint out. I may end up rebuilding or replacing the transmission but I would like to try oil first . If I have to replace the transmission should I upgrade to a k66 or another k46. If I have to replace the transmission I will contact you for what transmission will fit my tractor.
