As you can see from the photo below, my throwout bearing is all "chewed-up" (technical term). I assume this was caused by excessive contact with splines on the transmission shaft. After removing the bearing, I observed that the transmission shaft appears to be somewhat bowed. While rotating the shaft, I measure side-to-side laterial displacement of 0.073". The up-and-down lateral displacement is 0.146". With this much movement, I'm surprised that it was running with no major problem before disassembly.
Anyone had this kind of problem with their transmission? I'm wondering whether a machine shop can correct it? Thanks........Bill V

Bill,
Yes, a machine shop can straighten it... if it is really bowed. Maybe you could even do it yourself. It could be bowed if the tractor was split carelessly some time. Just like the axles, the machined surfaces should run true with each other, but the non-machined surfaces may have never run true.
Before they or you can do anything it will, of course, have to be removed from the transmission. With the shaft mounted between centers the surface for the front bearing should be indicated... while ignoring the rough non-machined areas.
Lacking facilities to mount it between centers, it could be done with V blocks and an indicator.

From the description it is lateral and vertical play of the shaft with the tractor split is the way i read it. If the shaft is not bent. the pilot bearing which can be seen on page 23 of the manual in Rudies manual is the cause. The pilot bearing is pressed in to the end of the crankshaft. It keeps the shaft straight and lined up so that it does not wondersideways or up and down.

Thanks, George. I really had not planned on this little surprise, but I shoulda known something was up with the condition of the T/O bearing. Guess I was in denial. Seems like everything turns into something more than I planned. OK, I'm done done whining - taking off the diapers and gettin back to work..........Bill V.

I read back through and now see the word bowed. The throwout has some shaft clearance and a well fitting pilot may keep the throw out from chewing up. Of course straightning or replacing may well be best. You may well have a damaged pilot too.

bill, it's hard to tell for sure from the angle of the picture, but it appears that the graphite block is worn down to nearly flush with the metal. If it's really worn that far flaking off at the center would not be unusual. To tell if the shaft is causing it look at the hole from the rear. Is the damage all they way through? Also if the dhaft is hitting it you should be able to see the worn/clean spot on the shaft.
If you are not part of the solution,
you are part of the problem!!!
