I'm trying to remove the generator from the engine shaft. It doesn't act like it wants to budge, and there isn't really any good place to hammer on it or put a puller on it. The long bolt goes in the end of the generator. Any advise? Thanks.

Most generators are held on to a tapered crankshaft.

 

You can remove the armature like you remove a flywheel.  Very carefully.

 

Use something to give you a little pressure prying off the armature.  Thread that bolt back into the engine crankshaft and then leave it sticking out a little bit.  While still prying down with some pressure, have a helper tap that bolt with a hammer.  With luck, that armature will fall right out in your hand.

 

The key word here is "very carefully."

Have you tried rotating the black fan to see if some bolts appear through the holes?

No. I did remove the four bolts that hold the generator housing to the engine block. Could there still be others be sides these?

Thanks, I'll give it a try. The fan being plastic makes things a bit more tricky.

That thing looks like it's been together a few days!  I'd try pulling/separating the gen. case from the engine block..  I'd try some wood & wodden shims to create some pressure and give it a whack with the hammer and see what shakes loose..  All I got..

 Buy some round stock large enough that will fit thru the gen shaft and seat against the crankshaft. Cut it long enough to stick out 6 to 8 inches and tap on the rod to separate them.

the last one I did I wound up taking a 4" grinder and cutting the generator rotor off of the engine's crank; did not hurt the engine at all and was scrapping the generator anyway (old Marquette brand starting unit like the tow trucks used to carry on them to jump cars with) But I did not resort to this as 1st choice only after taking the generator housing apart and tried many many other things to try and seperate them 1st.
