Humvee Generator Pulley

[Hummer Guy]

Has anyone ever taken the pulley off the 200Amp generator? I try to use a breaker bar and a big crescent wrench to take it off but this thing is literally just frozen. Has anyone else ever taken this pulley off?

What I was trying, was putting my breaker bar in the back and then try to use my crescent on the front to loosen it

I have always used an impact wrench, I have never messed with the clutch type though

It has the procedure in the TM. I was trying to get mine off also. I was able to get the one nut off but I couldn’t get the smaller one off. It shows to clamp the pulley in a vise and I didn’t want to remove the beast. My pulley was not the issue and I’m glad I didn’t remove it.

Why are you removing it? And which pulley are you referring too? There are 2

This not my generator but its similar, its the 8 groove pulley. My generator wasn't making any power and was making a really loud sound as if something inside is broken. I bought a new generator but it didn't come with any pulley so I'm trying to take the pulley off the old one and install it on my new generator

Why not use a pulley puller??

Don't have one at the moment, but I decided to just buy another pulley since I found one for $33

I almost guaranty the $33 one is not the one you need, unless the guy selling it does not know what he has.

I looked up the $33 pully...Its for an early surp 100 amp alternator......belt won't line up.
600634 is what you need...look it up at macmotors...$$$$$

That pulley is wrong, you must use the clutch pulley on 200 and 400’s with late style serpentine setup.

Yea, I see now, I found one of the pulleys for $226, I think I'm better off just getting an air impact and taking the old one off of mines or bringing it to a shop to have them take it off

The nut comes off with an impact driver, the pulley will either come right off or will get destroyed trying, ive done about 100 of them, most common in the pulley will separate from the bearing, leaving just the bearing still stuck on the gen shaft, if the clutch action is seized, just buy a new clutch pulley
