I was looking over a TK5 I just got and have a question. Whe I grab the input shaft near where it goes into the flywheel and wiggle side to side it moves a lot. If I grab it right by the bearing and do the same there isn’t much play at all. So the shaft doesn’t have much radial movement but seems to have some angular movement. Is the bearing a self aligning ball that allows for slight angular misalignment? It would sort of make sense with the other end of the shaft being held by the engines main bearing. I have no idea the mileage on the trans as the gauge cluster was gone from the truck I pulled it out of. I’m good with rebuilding it if I need to, but aside from that it seems very tight. Gears look good, no abnormal wear, no visible metal in the oil or anywhere else.

If you can’t fix it with a hammer, you have an electrical problem
The input shaft will have movement as you described. The main thing is rotate it slowly and feel or listen for any roughness. You are correct that the shaft will stay centered one installed into the pilot bearing in the crankshaft. Make sure to use the correct fluid and sounds like you will be good to go. That’s just an old mans diagnosis over a keyboard. LOL!

Thank you for the reply, the trans sounds pretty good. The guy I got it from has a private junkyard, he said he remembers it driving into its final resting place but had a weak motor. The oil is pretty black, should I flush that out with anything prior to running it? I was thinking just run it for a couple hundred miles after putting everything back together and change it again, but not sure.
