Mike,
Actually, the blade bolt is what holds the blade clutch on. It should just slide back on there, maybe a few taps with a rubber hammer. You don't want to snap the bevel washer on top of the armature. If it doesn't go on well, try cleaning it out a bit and make sure the key fits well. I always use a tiny bit of anti-sieze on the shaft to keep water out and of course, limit siezure.
Those blade clutches can be a pain, but my experience has been (while not as much as Harold, but still up to a hundred or so by now) that most come off fairly easy, and only a few do i have to add heat. I have a fixture set up on a large arbor press now that is working beautifully. Defini
tely HAVE to thread a hardened bolt all the way in to the armature.
Chad Getting the clutch body off of those mower motors is a pain. Now I'm wondering what method people generally use for re-installing them. The instructions I've seen I think just say to reinstall everything in the reverse order. The clutch body is just held on by friction, so it seems like there are two main approaches - pounding (and putting something like a block of wood over the flange to distribute the force) or pressing. I'm guessing the latter would be the preferred method, to prevent damage? If so, what kind of press do people generally use?Thanks,Mike________________________________Michael S.

I kept going with the bolt threaded in all the way (making sure I was using a bolt long enough that it could remain bottomed out without the head keeping the clutch body from coming all the way off - just barely). That one was a bit of a bitch to get off. But, as usual, I made it harder than it needed to be. I tightened the split bearing puller nice and tight to make sure it didn't come loose - and it was apparently gripping on the armature shaft pretty good, scraping it some as it slid up.

mos.phy.tufts.eduSubject: Re: (ET) ugh - bent / broke flange of blade hub Speaking from experience after removing scores if not hundreds of these clutch bodies. The key is to thread a grade 8 bolt in UNTIL THE THREADS BOTTOM OUT but the head of the bolt must not, may not, be down against the clutch body. I don't recall ever having messed up threads when doing it this way. Now, if you thread the bolt into only part of the threads, that is asking for trouble.
