Report "I have a Huskee Model #R608P . I'm replacing the lower drive belt & cant' get the engine pulley off the crankshaft. The electric PTO was replaced under warranty & I suspect they used an impact to replace it as I needed an impact to remove the crank bolt. I see the pulley has the key stamped into it.I've tried Blaster,heat,a pulley puller by hand & with an impact. Ant other ideas? The engine is out"
