Tech Tips – Using Tuff Torq Repair Kits
Tips for Tuff Torq Repair Kits
(K46, K57, K574, T40 MODELS)
The Tuff Torq service team has put together this summary outline procedure for using our Tuff Torq repair kits to service your drive system. These are just tips and should not be considered a complete repair guide for every issue you might have. All repairs and maintenance of our drive systems should be performed by a professional service technician. If you have any questions or need specific help for your issue, feel free to contact our service team at (866) 572-3441 or through the website by clicking here.
Receive the correct repair kit
- First, clean the outside debris from the unit.
- Be sure to locate the proper serial number of the TTC unit (Located on the barcode sticker).
Removing unit for repair
- After you have received your parts, please inspect the parts. Note the mating surfaces must be smooth and clean.
- Repair Kits generally include the center case, pump cylinder block, motor cylinder block, filter, o-rings, seals, and sealant. When repairing your unit, it may not be necessary to use all o-rings, and seals.
- Drain the oil from the unit. (DO NOT reuse the oil) Remove the flat rubber seal cap located under the fan to drain the oil. No need to remove the vent valve.
- Place the unit on your workbench with the fan facing down.
Opening unit an performing repair
- Remove the case bolts and remove the lower housing.
- Scrape the sealant from both the upper and lower cover. Be careful not to damage the sealing surface while scraping the housings. (Remove all sealant completely)
- Now is the time to use the drawing and parts list from TTC’s website to identify everything inside the unit www.tufftorqservices.com.
- Clean and flush the unit. Improper cleaning of the unit could result in a premature failure or void the parts warranty. You can clean internal parts with standard brake cleaner.
- If you choose to inspect any parts make sure these parts are placed back into the proper orientation. (Ex. If you remove a bearing or a plate make sure that it is placed back into the proper position. Plate with smaller ID (INSIDE DIAMETER) should contact Pistons.) The notes are listed on most drawings so be sure to follow these tips properly. (see Fig#1)
- Note the original position of the Motor Housing. (see Fig.#2)
- Once you are ready to install the parts be sure to coat the mating surfaces with oil. This will help lubricate the contact surfaces.
Re-assembly of unit
- Make sure to re-install the bypass pin and washer from the original center case and motor cylinder block. You can use a light amount of automotive grease or Vaseline to keep these two parts in position while putting the parts back in.
- If the unit has IDS valves, be sure to note the correct position of the ball or the filter compared to the drawing (see Fig.#3).
- New center cases will have pilot holes for the IDS system. See figure 4 to understand the difference between IDS and non-IDS units. The non-IDS unit will not have finished machining at the pilot holes. This is simply in the case mold design of the new center-case and does not impact the performance of your unit.
- New style magnet holder and two magnets (see Fig.#5 on back) for proper orientation.
- After re-installation, check to see if everything will rotate freely.
- It is critical that the operator maintains proper oil levels at all times.
- Maintain oil level at 20~25 mm (3/4”~1”) below the lip of (black cap) the filling port.
- Always check oil level when the oil temperature is at room temperature (20C or 68 F).
- When replacing oil in your unit, Tuff Torq Corporation recommends using Tuff Torq Tuff Tech™ hydrostatic drive fluid when rebuilding Tuff Torq transaxles. (DO NOT use ATF Automatic Trans Fluid)

I have a John Deere 14.5/38 Sabre riding mower. It has a Tuff Torque 51a . The right rear axle seal was leaking. I obtained the part and found the time to replace it.

I want to be clear about the fill port on my JD 125 automatic lawn tractor T 40 transmission. Is it the metal cap forward or the rubber cap at the rear? Also, low vis or high vis oil?
I wanted to see about getting a rebuild kit for my transaxle. It’s a k46., It’s on an ’05 John Deere L120 GXL120A082485.
The bar code sticker that y’all put on the axle, the numbers aren’t readable except maybe the first four or five. I can send a picture of what’s there if you scan the bars maybe. I pulled it out a couple of years ago and refilled it with synthetic 5w50 I think it was and it helped the slipping some. I did it again this past spring and it helped again but it’s beyond that now. How can I identify for sure which model it is? It’s screeching bad and reverse will work a little. Will the rebuild kit get me another 2-3 years out of it? It’s only got about 500 hours on it.
When I take out the ETC Diff Comp I can turn it by hand in both directions and both sides when I place the axle in it. Does this mean the unit is worn?
Hello, I have K46-1A6460-84300#3 on the housing of my transmission. I need a rebuilt kit. What do I need and do you have the number of the required kit for this repair.

and where to take it to buy
Tuff Torq Rep., I have a John Deere LA135. The transmission is having issues going up hills after it gets hot, about 15 mins. of running, but it works great on flat land. Every two years I have removed the transmission and changed the oil in the off season using Mobil One Full Synthetic 15W-50 oil each time. After a lot of online research, I understand going up hills will generate a lot of heat on the transmission, resulting in this issue that I’m having. I believe that my best option, because I do like my John Deere, is to rebuild the transmission with the “Tuff Torq repair kit”. The following are the numbers on the transmission:
768T202411 – 40J-0613329 JDPP PH MIA10910
I live in Knoxville, TN and go the Johnson City, TN often to see family. So my question are:
> What is the rebuilt kit part number that I need?
> What is the cost of the kit?
> What is my best and lowest cost in shipping or if available can I pick it up?
> Would using Amazon prime be a good way to go about ordering it?

I have this trans below 7A646024390 Ser. 46ac0246609 JDPP P/NAM131580
When I step on the gas and I am going forward it appears at some points to make a clunk as the clock happens forward movement momentarily stops and then goes again. It seems to only happen when the transmission is stressed a bit by either going around the corner or if the front tire it’s a hole during a turn. Would you have any idea when I might need?

What would be the part # for k57 upgrade kit. I read the charge pump increases durability. I want to upgrade center case / pump shaft/ charge pump…
I gave my trans to a repair shop, and he gave it back to me in a basket, took me a while too figure out what was missing as I put it together.
I noticed in pics after reinstalling I did not see or remember installing spring #1A646099070 under pump. Would trans still work w/o spring? I resurfaced center pump and new motor & pump.
it works but trans looses some power when hot. so I want to replace center case with charge pump next time i pull apart.
I just finished installing my k46A trans and working OK I never liked the speed of this tractor (LTR180) the problem is cannot get to trans mision to clean because of the shoot (center rear discharge) I’ve read that the k66 trans would not fit my tractor, but can I fit the k66- pump, motor, wash plate, shaft, charge pump… into the k46 trans?
I’m working on my K46BT, serial number 46BT1060678. TT # 7A646084181. I thought I had taken pictures of everything before I disassembled everything.. Well, I must not of and I can’t remember the orientation of the motor drive block. I can’t remember if it was thick side up or thin side up. Any help would be appreciated.

K46 Rebuild Kit
I have a K46 in a 2013 John Deere with 140 hours on it that has broken springs under three of the 5 pistons. I took a fourth spring in my fingers and it snapped like a pretzel would if you tried to bend it. There is no visible scoring or discoloration that would indicate overheating and makes me wonder if there was a bad batch of springs from your supplier. How do I order all 10 replacement springs and what are their p/ns? My axle info is Model: 768T2024011 S/N: 40J-1320433
I have a John Deere Lt160 with a Tuff Torq K46C Serial # 46C-0077400 Transmission with 2000 hours on it. I all of a sudden lost all drive. The belt and pulley on top of the transmission are good.

Hello I just got a riding mower with a 46BA hydrostatic, the plunger in the back to roll freely was in the locked position, once i got it home I unlocked the plunger to roll freely, after I started the mower, I engaged the plunger the mower did not move, took the unit off drained fluid, was not full, took the cover off, didn’t find anything broken or out of place! I seems the plunger or mechanism to to lock the wheels from free roll may be the problem.
I can’t find any references or picks to show that part!

Hi, I have just refurbished my K46 transmission and replaced the pump, motor and gears. After I had it all back together I notices a small O ring on the bench and I have no idea where it came from. I looked at the assembly diagram and could not figure out where it may go. Can you provide any details on where the O ring needs to be. There are many O rings in the refurbishing kit but it says they do not need to be replaced. The one on my bench was like the the smallest one in the kit.

Hi, can forward and reverse be swapped around by installing the motor housing other way round?
Do you have a rebuild kit for a 46Z transaxle
Nevermind, I figured it out. After taking a break and clearing my head, I took another look at it. What happened was that when I tried to pull out the original axle seals, I pulled the rubber away from the metal band insert that gives the seal it’s shape and rigidity. That’s why it seemed like it was melted or glued on. Because it was at the factory where it was molded. With a little more force I was able to get that metal band out and was left with a nice clean opening for the new axle seals to go into. Sorry about all that. Maybe you could remove my previous post? And this one? Since it’s a non-issue. Thanks Again. Sorry for wasting your time.
Trying to replace the axle shaft seals on my K46BE. S/N 7A646084120. The seals (#72 187T0134280) that came in my repair kit (1A646099601) will NOT FIT in the original housing. Removing the originals was nothing like any of the repair videos I’ve seen. They almost seemed glued or melted to the housing. Took a lot of careful scraping to get all the old material off of housing. The chamfered opening is the exact diameter of the new seal, but the just inside the housing is what looks like a pressed in bushing. Part # 74 168T203424. So the new seal is so thick, that it bottoms out against that bushing before it comes anywhere close to properly being seated. Are the wrong axle seals being put in the repair kit? Should I remove the bushing? Which appears to have been pressed in anyways. (Doubt it. Also, don’t know how one would go about removing it anyway.) Also on the original seal….did you guys use some type of sealant between the outer circumference of the axle seal and the inner walls of the housing? Seriously, it was like the old axle seal was almost melted or glued to the housing. One other simple question. What does the acronym IDS mean? I.E. Ball IDS/Filter IDS Thank you for any help that would shed some light on this.
Don’t want to put that much money on this job just want the $71 cylinder block repair & the transmission seal service kit what is item # thanks ?

Moro no Brasil tenho um microtrator husqvarna com transmissão K46, mas não consigo saber o tempo de troca do óleo da mesma e o pior, que óleo utilizar, com isso ela foi ficando fraca. Um revendedor do trator me indicou óleo sintético 5 w50, não encontrei o mesmo, me mandaram colocar o 10w40 funciona por 1 hora e quando esquenta ficar fraca, espera esfriar e usa mais uma hora. Acabei por trocar a transmissão por outra nova e não sei como farei a manutenção da mesma. Se possível me indique o tempo de troca do óleo e um tipo de óleo que encontre no Brasil. Obrigado pela atenção.

Hi, I have a John Deer 115 which has the tuff torq drive unit and has lost all drive power. I was just wondering if it is worth repairing this by replacing the pump and motor kit or should I just scrap the complete machine. I’m not sure how much the repair kit is yet but I understand it is going to be quite expensive. (if the machine were working it would be worth about UK 450 pounds, aprox 550 USD).
Any advice would be most appreciated
Good to know
