Friend picked up a 10,000 watt Generac last week with the 18HP (looks
like a Vanguard) twin on it - looks like new, but the bolt holding the
gen-head rotor to the crank either broke or came loose, and the
end-bell has the bearing counterbore all worn out of it, and the rotor
runs out of true.

He's trying to pull the gen-head rotor from the crank. I've suggested
tapping the end of the rotor shaft, and putting in a plug with a
grease fitting, filling the hole with EP90 gear lube to displace all
air, then pumping it up with a grease gun to force it off. He has
threaded it (1/2" UNF) and made the plug, but wants to know if there
is anything else he should be aware of before trying to
"hydraulically" remove it.

If the rotor is shot, give it a few whacks with a BFH, the vibes from the
hammer hits will loosen it. A couple hits on the shaft where it couple to
the engine will do it. Back up the other side of the shaft with a bigger
BFH. I have removed many rotors this way, tons faster then any other, and if
done carefully you will not damage anything.
