Then, try spinning the cover either by hand or tapping the cover SIDEWAYS (in relation to the crank) with a block of wood/hammer. We're just trying to break the bond at this point..

Crankshaft stuck in kohler riding mower engine

I saw another topic on this but it won't load...I removed the flywheel, heads, cam, and piston rods, to see why the engine was locked up. I found that the crankshaft is stuck in the upper bearing, flywheel side. The crank won't spin and I haven't been able to get it out by hammering on it. How else can I remove it?
