Default Tecumseh HH100 - 10hp - Generator Removal

Good afternoon, does anyone have any tips on removing the generator auger from the crankshaft of an HH 100? I have remove one from smaller took out some motors but this one is different. I do not have a poor but I would probably buy one for the purpose, if I knew it would work. Thank you.

Well, I may get chastised, but, how I've gotten them off, (I assume you've removed the bolt from the end of the armature) Is to take two, 3 to 4Lb hammers and strike the laminate sides at the same time, close to the engine. It's on a taper, and that's how I also loosen a ball joint or tie rod end. It may take several tries, getting both hammers to hit the laminate at the same time. It will set up harmonics that will easily loosen it. You don't have to strike with all your might, just a good solid hit with good force.

A slide hammer might work wonders.

For tapered shafts in general....
Protect the end of the shaft with whatever is appropriate.
Then exert pressure on the female part in the direction you want it to move while you smack the end of the shaft solidly with a hammer.

I did that once. 1st loosten the thru bolt that holds the generator shaft to the engine shaft; run the nut flush at the end. 2 nd , before you remove the outer shell of the generator which has the stator, loosten the bolts that hold it on ( 4 ea) and place a cold chisel where the parts meet. Gently make space between the two parts and put a shim in them. The end play of the engine crank shaft is all it takes. 3 rd , place a piece of scrap aluminum on the nut at the end of the thru bolt and rap it with a hammer. The idea is that we use the generator housing to hold the end bearing away from the engine and the rap on the thru bolt pushes the crank shaft to separate the tapers.

I just did this on a Tecumseh HM80 generator set a few times. I have smacked the armature on a couple of units, with success, but this one someone had already hit it a few times and I didn't like how it looked.

I went on line and found this page straight from Winco and it worked for me, easily. If you can get a bar in the right place without hitting something you shouldn't, it might work for you:

REMOVING AN ARMATURE OR ROTOR FROM THE ENGINE CRANK SHAFT
The armature/rotor is just taper mounted to the engine crank shaft and held
in place the bolt running down the middle of it. Remove the bolt or nut and
washer before continuing.
You will need a flat metal bar and good steel hammer. Insert the flat metal
bar between the end of the armature/rotor and the engine, so that is rests
on the engine crank shaft. Strike the metal bar crisply with a steel hammer.
This will set up a vibration in the hardened crank shaft, the vibration should
break the seat between the armature/rotor taper and the engine crank shaft
taper.

I could just barely get a bar in place and I just placed the bar end on the shaft without knowing exactly what part of the shaft parts I was on. I gave it a few sharp wraps with a hammer on the end of a steel bar and the armature popped off. I had made a "bed" for it to fall on in case it fell completely off.

Thanks, I have and air hammer and attachment I used for my HS40 but is a larger diameter auger and I cannot reach the actual crankshaft, or at least I have not figured out how to yet. I might be making a trip to Harbor freight tomorrow, thanks.

Most of the times I just loosen the through bolt a couple turns out and use my air hammer with a round blunt bit to shock the head and the rotor usually breaks free of the taper. Or you could use a brass hammer on the bolt head but be careful
