PTO stuck on bearing

William_cj3b · #1 04-25-2026, 04:43 PM

The hub of this PTO is siezed on the bearing. I have all 6 set screws out. I'm considering cutting a couple of the fingers or drilling the heads off of the screws so I can get a puller to push against the bearing or crank. Right approach?

I tried searching but didn't find any threads on this exact issue. Any tips or tricks?

Get out you Ralph Kramden and a chisel and knock the fingers off and remove the button and the spring to expose the drive shaft end. You can use the puller then...

Parts by Jeff, Sponsor at top on home page makes a great puller
for these PTOs. Used it many times, has saved me alot of battles.

Yeah, that's after you get the PTO off without destroying 1/2 of it in the process!

Best to start soaking the PTO proper with your favorite penetrant through the set screw holes and tapping with a hardwood block around the diameter of the pulley sheave of the PTO.
May take a while,...... as in days.

Best to avoid this situation in the future, store your equipment inside and out of the weather in the first place. Evidentially, the PO did not!!

Good luck, and don't give up.
A properly restored & maintained IH Cub will give you decades more of good service.

Yeah, this is a junk/salvage piece that was given to me many years ago in this condition... hoping to salvage a few pieces from it and clean house a little. I took the picture before a liberal application of Kroil.

Well, that being said, looks like you have plenty of .....time then

After I get the set screws out, I used a large bearing puller instead of busting up the fingers and thrust button.

After that, youve got the bearing and then the basket pulley. Jeff in PA (sponsor ad above) makes basket pulley puller.

I don't have a large enough bearing puller, so I compromised. I drilled the head off of one of the finger screws then popped the button out to remove the springs. A 3 jaw puller made almost instant work of removing it.

I have the bearing lock ring soaking now. Set screw is out but I can't knock the ring loose just yet.

I pulled the head off while I'm waiting. The cylinder looks good and the valves are operating as they should. I believe this engine would run with some work on the governor. Guess my spring cleaning has become a new project!
