Removing crankcase cover on Briggs & Stratton generator

Hi,

I've got an old PowerMate 54 series 5000 watt generator with a 8HP Briggs & Stratton engine on it that I believe has a broken crankshaft. I'm trying to disassemble it to verify and cannot get the crankcase cover off because I cannot get the rotor part of the generator off the crankshaft. What is the best way to pull these off? I can't use a gear puller as the top of the shaft is not part of the crank but integral to the rotor.

Thanks,
Kevin

Hello Kevin,

Some people have gotten them off successfully by loosening the bolt that holds the armature on, then hitting the end of that bolt to "shock" the armature loose from the shaft. This hasn't ever worked for me though, and you rik ruining the bolt. I have had success by removing the bolt, and rapping the armature on the side a bit with a block of wood to free it from the shaft. The shaft is tapered, and the sideways impact seems to break that wedge fit of the taper.
