I'm working on a Wheelhorse rider with an 11 Hp Briggs. I need to get the electic PTO clutch off so I can pull the motor to fix an oil leak. I removed the main bolt holding the clutch and drive pully on the crank shaft. The crank is keyed, not tapered, so everything should just slide off. I tugged and pryed with no luck. I even tried getting a "puller" on it with no luck. I'm afraid i'm going to break the clutch. How do you get these things off ? Any help would be great. Thanks.

It's probably has some corrosion on the shaft that is causing the clutch to bind and not slip off, this is not uncommon. I have said it before and I will say it again, I have very good luck using an air hammer on pulleys, clutches and adapters to get them loose and off.

Good Luck :thumbsup:

Thanks 30yeartech. I'm not sure i understand what you mean. Can you please tell me exactly how and where to use the air hammer? or do you mean air chisel? The bolt holding everything on the crank is removed. I just can't get the clutch and pulley to slide off the crank. I thought that a wedged shaped ball joint removal tool might do the trick. But it only had a 3/4 inch slot in it, i need a 1 inch slot to fit around the crank shaft. I also thought about putting some heat on the pully hub, but i'm afraid i'm gonna mess-up a $225.00 clutch.

I mean a pneumatic impact hammer, but I guess you could call it a chisel as well.

No don't torch the clutch you will melt the coil windings and you will mess up a $225.00 clutch.

Just apply some pressure on the clutch (perhaps with the puller you were using) not a tremendous amount, then just use the impact hammer with a dull chisel bit on an area that won't be damaged. The vibrations usually will loosen them up and once they start moving you can generally get them off. I like the area just above the pulley if you can get to it while it mounted, if not just try going in a direction like you are trying to install the clutch, you are just trying to loosen the bond between the clutch and the crankshaft.

Good Luck

I was only gonna use heat as a last ditch effort to get the clutch off. I know it would have messed it up. Anyway, I did as you said and tried to use an air hammer but it would not budge. So I figured i'd put the puller on the lower pully and use an air "wrench" on the puller and see what happens. Presto, the lower pully came off. Then I pulled off the rest of the clutch. Now all I have to do is remove the drive pully from the crank. It's stuck just as bad as the clutch. Wow, the newer mowers fall apart as you use them, and this older one that i'm working on seems to be welded together.

Thanks 30yearTech for all your help.
