Any tricks or tips on how to get this bearing off of the jackshaft? This is the one on the clutch side that sits within the mounting plate. I've used heat but no luck so far. Thanks

A 50ton press works best though...

Using the press was going to be my next move just wanted to get some input. I'll try a 1" ish wrench and see if that works, might take two people. One to hold the shaft one to hit the wrench

If the bearing wasn't wrecked before it is now! Lol

It can work. If you have access to a press though, that's the way to go. They're on the shaft pretty tight.

Thanks, I will give that a go. What do you recommend for putting the new one, just grease the shaft and carefully use a mallet and wrench to push on?

If you can find a piece of pipe the right size, that would be your best bet.

Use wood on the end of the shaft so you don't beat it up.

Success. Thanks for the help, the broken pto plate worked well as a plate to push the bearing against in the press haha

Freeze the shaft and warm the new bearing up a bit is what I do, not too hot to damage the grease though. Also you can keep the old bearing, grind out the ID a bit so its loose on the shaft, then use it to push against the new bearing.

I recommend this post.

Leave the shaft outside to cool the shaft, the colder the better. The shaft diameter will shrink by thousandths of an inch.(good old sask -30 temps).

Heat gun the inside collar of the bearing, which will increase inside diameter of the collar by thousandths of an inch.

Quickly drop the bearing on the shaft, should practically fall to the bottom. Once the bearing cools and the shaft seats back up it will lock into place.
