Tech Tips – Strider™ (w/ External Expansion Tank) Oil Maintenance

Oil Maintenance Procedures for Strider™ (K46) units with External Expansion Tank

Designed to be trouble-free

Normally the Strider™ transaxle (K46), that 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 & 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 oil to drain from case through the port under black cap.

Refill transmission case with oil through same port to near top of 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 recommended oil level. (see Figure #2 below for recommended oil level).

    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.
