T20 Skid Steer Rebuild

Reinstall the shaft retainer ring.


Install the shift collar back on the shaft. Make sure that the detent spring goes around the shaft and doesn’t get pressed up in the collar.


Put a new thrust washer on the ring gear drum.


Install the ring gear drum on the shift collar and make sure that the new thrust washer you just installed stays on.

TIP: To help keep the new thrust washers from falling off you can apply some ATF to the washers before you install them. This will help them stick to the drum or any other part during assembly.


Apply a new thrust washer to the ring gear drum that you just installed.


Install three new thrust washers on the outside of the planet gear / needle bearing assembly.


Install the carrier plate on top of the washers and then pick the complete carrier drum assembly up as one unit. Install it in the T20 transmission making sure that the planet gears align properly with the ring gear drum.

TIP: If you can’t hold the assembly together with your hands you can always just tie some string around it and then remove the string once everything is in place.


TIP: If you tilt the transmission on its side it is much easier to install everything as a complete assembly. You can also just install the carrier plate, washers, planet gears, and the carrier drum separately but it is a little more difficult to get everything lined up inside the housing.


Install the band anchor rod and sleeve.




Now you can reassemble the other side. (go to the next page)
