Mis-spelled Kohler.  Sorry.

I have used the 3 jaw puller, sprayed with PB blaster and removed the two allen set screws. Lastly I heated with a smaller propane torch.  Eventually I thought it was coming off, but rather it broke.   

 

Anyone have tricks other than taking it somewhere that has a big torch and turn it cherry red?  I have a new crank seal and a new crankshaft coming.

 

BTW, anyone have a pulley they could sell me?

I would try a flywheel or harmonic balancer puller with some good grade 8 bolts in to the threaded holes.  If that can't get it, I would cut it off.  You always wonder how those stupid things get stuck on so hard.  One time I had a centifugal clutch stuck on a Tecumseh, and I finally had to take the cutting torch to it.  It was like it welded itself to the crank.

Double check and make sure you have the set srews loose. i have seen them double stacked to lock then in

I second what WH nut said, I have seen many a time set screws double stacked. Came that way from the factory some times. I messed a crank up that way one time. Thought I had all the set screws loose only to find one still in there. Pulled the pulley off with a puller and left a groove all the way down. Never forgot that and now I always check.

Another vote to ck for stacked set screws - I rebuild machinery as a hobby also and MANY machines have double set screws. I'm just finishing up a 1054 with the 10hp Kohler and the drive pulley was begging for adding a second set on it - which I promptly did.

Lot's of machinery have stacked set screws, found out the hard way. If not, a real torch or a a smaller one held on target for a while to make sure things are good and hot should do the trick.

I put a pick down in there to clean it out so the blaster would get in.  No double stacked this time.

 

I guess I will have to get a bigger torch.
