To20 axle hub seal doesnt fit

[Fergster]

Just got my seal and bearing kit from yesterday's tractors and started to assemble it when i noticed the outer wheel seal just drops on the hub. The od is supposed to be 3.505 and these seals were .010 to .015 smaller. Also the inner seals od is way smaller. It had sure seals on it. After looking in the manual i dont think the to20 had an inner seal. The outer seal that was in it was a national 416271. So either its a typical manufacturing defect or there were changes during this model run which i dont think is the case. I still dont know what that little sheet metal ring is from my other thread either

I answered my own question. The sparex seal from englands dimensions are listed in mm and works out to 3.488 so its not the seal. Its for a te 20 and not the us version but yesterday's tractor lists it as fitting the te and to 20. I guess its shim stock or buy the national seal

There is no inner seal on TO 20 unless you add a Sure Seal. I pack bearing with grease and I stall Sure Seal.

I used .008 shim stock cut half inch wide and cut to the correct length and was able to press the seals in place and then i discovered the new bearing races just pushed in place. I micced the new and old bearing. New is .0025 smaller. Its the right number so now i have to address that. What a pita

Bad luck for sure. Different bearing might be in order. I have used LocTite stud and Bearing mount with shims when race receiving receptacle was messed up. This was not on a TO20.
