I offered to repair my neighbors snow blower. He has an MTD 10 hp walk behind, that needs a new multi-position bearing on the auger shaft. I n order to remove it I have to remove that 12" pulley. It is quite stuck and has no provision for a puller. I have tried everything to wedge it off. I've used PB Blaster and have now mixed up some ATF and acetone. I'm almost tempted to drill a couple of holes to install a puller, but this just seems like poor workmanship. Any ideas?

Air hammer on a block/piece of metal might loosen the pulley

If you can get a bolt behind it just drill three holes & use a puller with grade #8 bolts..  (& 'fire-wrenches' of course!)

That's the option I'm saving for last. I've' been trying to wedge between the hub and collar you see in the picture and then hammer on  the end bolt with a block of wood and it just doesn't want to let go.

How big is the shaft??  (I'll wager it's one inch)..  A pickle fork should do the job and not distort the pulley..

There looks like plenty of meat in the hub to drill and tap for a puller. That and a little heat should do it.

What about using a large bearing seperator?  Maybe can rent one from a tool rental place.  I think the tin pulley is only gonna bend trying to get it off with three bolts if it is as tight as you are describing.  I never have great luck with those tin pulleys.

pickle fork and vibration such as a air hammer on  piece of buck stock metal, that might take an extra hand though

The pickle fork sounds like an idea. I'll have to see if I can borrow one. I don't have an air hammer or 'fire wrench'. This is a small time operation. :D

good luck with getting the pulley off, all of the suggestions seem to be what you need to do.

The ball joint tool worked like a champ! Now,  if Amazon hadn't sent the wrong bearing, I would be almost done. :ah_shoot:
