Model B clutch bearing

Hi again. Seems for every answer I have 5 more questions.

I pulled the belt pulley off to check for the knocking noise I am hearing and now have another question. There is a roller bearing in the end of the belt pulley. How do I get this bearing out to pack it full of grease.

Thanks

If the bearing looks/feels good repack it
& don't remove it. Clean it up good with
solvent & repack, caged bearing with a
outside race..
 
I have to keep repacking mine. Should have replaced it, but packing it is the easy route so far. Gonna replace it maybe this summer. Just one of those things that can be left alone for a while but needs to be replaced eventually.
 
If you had the owners & repair manuals, you would know that they are supposed to be cleaned & repacked Every Year. Whenever it's running & the clutch is disengaged, this bearing is whirling away on your crankshaft.
 
My 51 B has never been rebuilt. Bearing sounds awful. The previous owners didnt know squat about this type of maintanace. I dont run it much. I just keep limping it along, with the clutch engaged while idling. Someday I'll have the time and resources to do a rebuild.
 
The manual also says the clutch is to be ALWAYS engaged when engine is running. Take it out of gear & engage it. Always. There are two reasons for this. First is SAFETY. If a floating disk breaks in half- and they do- it will lodge between the drive disks & engage the clutch without warning & with no way to stop. This DOES happen. The tractor takes off in whatever gear the operator has it in, VERY dangerous- deadly. The second reason is to avoid massive wear on the clutch bearing, clutch bushing, & Crankshaft. It also wears the locator pin due to rattling around. I cringe walking around shows & seeing all the 2 cyl JD's idling away, with the clutch disengaged ;-(

You will have to remove the entire clutch. I had to slide the right wheel out on the axle to get enough clearance to remove clutch. When you get the clutch removed, lay it on table with gear facing up. Use something that is not sharp, go down through hole in bearing, and drive out the retainer that holds in the bearing. The bearing will then be easy to remove. You can reuse the retainer if you are careful. I had to replace bearing and inner bushing because of too much up and down slack in pulley and clutch assembly. Some may hand pack without removing bearing, but I had to tear mine down. If you do that you may not have to remove clutch. James
