Thu Aug 22, 2019 7:58 am

I have a 36hp motor that we're trying to rebuild, but the cylinders are stuck solid in the case. Any tips on how to remove them? They've been soaked with WD40, heat has been used, nothing seems to help. Is there some kind of puller that can be used?

rubber dead blow. smack the cylinder all the way around, and then at about a 95 degree angle and they should come out. the piston isn't rusted solid in there right?

I'm thinking there's oxidation and electrolysis who ganged up to make your life hell.

Have you tried the ATF /acetone combo? I really can't think of anything special, like VWporscheGT3 said, a rubber mallet and patience, look out not to break fins.

Ever had to cut them off with a die grinder? I have

Heat the case not cylinders, maybe put two studs thru opposite corners of cylinders and long bar between and try to twist to break bond? maybe less chance of breaking fins, check case drain plate, maybe all corroded and case junk, as was the last one I tore apart, busted cylinders and saved crank,rods and flywheel

When the rubber mallet doesn't work, get a real hammer and get medieval with it.

I’ve had to break them off before too.
Usually though, those were junk yard or back yard engines that sat in the elements for a few years.
