T20 Skid Steer Rebuild

Clean the housing again paying close attention to the surface that the seal is against as well as where the main gasket used to be.


Install the new bearing.


Install the bearing lock ring by working it around the groove.


Then tap it into place and make sure it gets completely in the groove.


Tap the oil seal evenly into place.


Again, an optional step that could save you trouble in the future, take a punch and ping the housing in four places to ensure that the oil seal doesn’t come back out.


If you haven’t already, remove the old orings from the T20 brake band plungers.


Install the first brake band in the T20 housing. It is the band with the anchor point on the bottom and the plunger on the top. Insert the plunger through the housing without the orings. Make sure that it is lubed up before you push it through. Again you may have to insert the bolt in the plunger and pull it from the outside.


Liberally lube the plunger with vasoline. Coat the new o-rings with vasoline as well and install them on the plunger.


Install the bolt and washer on the plunger so that it does not pull back through the T20 housing. Then push the plunger into the housing.


Install the upper brake band in the same manner. This band should have the plunger on the bottom and the anchor point on the top.


On the input shaft there is a small outer seal to replace. You just remove the old seal and then tap a new seal back into place. I used a large socket that fit over the input shaft to tap the seal evenly. Just be sure that the inner part of the seal doesn’t get caught on the input shaft and tear.


Put the input and output shaft assemble back in the transmission housing.


Reinstall the shaft retainer ring.


Use those handy pliers once more to spread the retainer ring and get it in the groove.
