Help removing generator armature

[wardog]

Alright guys, I have been fighting this for a couple hrs. I am trying to separate the engine and generator on an old Kohler 3500 watt gen with a Briggs engine. The issue is that there is no shaft bolt holding the armature to the crankshaft..... there is no hole for a bolt to go through. There are tons of how to's I have looked at, but not a single one addresses a generator without a hollow shaft and no bolt holding the armature to the shaft..... HELP!

If the Armature has no way for a through bolt to be installed, it is possible that the engine has a Straight Shaft and there is a set screw of some sort retaining it. Straight Shaft generator engines are few and far between, but there are some out there.

Pictures would definitely be helpful

A keyed shaft would be awesome, but I cannot find any set screws or holes anywhere.....

It'll most-likely be tapered shaft and the armature is press fit or heat shrunk on, so not usable.....

Get a cutting torch and give her heck...

Worse comes to worse and you find a straight crankshaft and bolt it in. Looks pretty rusty, I'd get some PB Blaster and soak the living daylights out of it for a good day or so, then soak it again. After that keep trying to get it off. Could be a manual out there for it that might be of use, or take it to a small gas engine shop and let them mess with it. Sure it'll cost you money, but at least itll be done the right way and they could hopefully get a proper crank for you.

Maybe it's threaded on. This is from a kohler gen.

Randy, you are THE MAN. Thank you soooo much. I had considered it being threaded, but you gave me the confidence to really smack it.

The other good news is that it is a 1" shaft..... just needs a keyway cut.

Just remember that 1" clutches are generally more expensive than others

Well thats a new one..... Im glad you got it off....Thats amazing...
Also it good you might have at least a potentially usable shaft to use... Might be better off to get it machined down to 3/4"... the cost you save on the clutch will be towards the machining cost....

The plan is to just grind a keyway in it and throw on a $70 Amazon TAV2.
I'll probably build a trike for it.

OMBWarehouse has them for $70 also.... they are imports, Chinese I'm sure, but the reviews are generally good.

We have not heard any bad reviews of them either.
