how to remove a stubborn pulley?

I need to replace the pan gasket on a 24hp intek briggs twin, and cannot get the pulley off and out of the way. I tried everything I know, including a split puller, which simply mangled the pulley and never budged it. I have thought about a slide hammer, but would that hurt the engine, jarring it that violently on the crankshaft?

Does anyone have any suggestions? Is there anything I could have missed, holding the pulley on?

If you removed the 5/8" bolt up in the bottom of it,,,then rust and corrosion is the only thing holding it on.

There is a key way on the pulley,,but not removable. Just a raised area on the pulley that fits into the slot on crank.

Is the engine still mounted in tractor?? Heat may be the way to go.

" I have thought about a slide hammer, but would that hurt the engine, jarring it that violently on the crankshaft?"

I use a blunt bit in an air chisel to get behind and drive them off IF there is enough room. Otherwise, I have a write up on how to remove them with out damage but I guess that is of no use to you now. As said above, may as well cut it off now.

Re: how to remove a stubborn pulley?

I've had the same experience with a drive pulley on several garden tractors.

Ended up using a torch and porta-power.

These are the pulleys that the manufacturer states must be removed to change belts.

Now I just loosen the entire engine instead.

Re: how to remove a stubborn pulley?

I'd tack weld a nut in 3 places around its O.D. to the pulley,and use a long threaded bolt or threaded rod ,screw it in,to "push" it off the crankshaft...might still need some heat and penetrating oil(if you do it fast right after welding the nut on,it might be hot enough to come off without additional heating)......dont heat it so much the seal in the engine melts though...

I've used that method many times sucessfully,and if you are careful,you can get the pulley off without any damage,and grind the welds off and remove the nut,and re-use it...works well on stubborn rear rims that "welded" themselves to the axles on tractors that had keyed bore rims or ones with thru-bolts securing the rims to the axle shafts...

Got it off. Had to cut it, and even after cutting a slot down the length of the collar on the pulley, it still had to be knocked off with a hammer and punch.

Re: how to remove a stubborn pulley?

when I had that problem,I sprayed PB on top of the pully so it would run down between the crank shaft and pully,short time later slid right off

Re: how to remove a stubborn pulley?

Thanks,
I tried spraying liquid wrench around it yesterday, I'll try another application next time I can get at it.
I'm trying to get a Kohler engine off of my lawn tractor, and this was (of course) the last step and only obstacle.

Re: how to remove a stubborn pulley?

It never hurts to apply some never-seize or grease to the crank when you have a pulley or sprocket off ...saves you from future grief !...too bad the manufacturer's don't when they build things..
