Loose clutch pulley

Recommended Posts

The clutch pulley with the big nut on the end of the BGB on my 716H turns a fair amount by hand without moving the shaft (rotates maybe 3/4 inch). Is the BGB shaft probably toast? The nut appears to be tight, and all attachments work fine, but I'd like to make it right before it breaks in the middle of a mow job. I have manuals to fix it if that's what I need to do.[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]

The woodruff key,clutch keyway, and keyslot are probably worn out,,a common problem New shaft is maybe $60 A new clutch drum is about the same price? And while your in there a total re-build of the box should be done,,

If you want to make it last just a bit longer before you rip things apart, take a small die grinder and clean up the sides of the woodruff hole in the shaft. Square up the pulley key slot with a file as best you can. Then take an oversize woodruff key and file it to fit as close as possible. Put the whole shebang together using Loctite 609. Amazing stuff. You WILL need a good size press to get it apart later. But, so what, the shaft and likely the pulley is shot anyhow. Chris

Some where in between might be to cut new keyways in the shaft(s), pulley(s) and gear(s) as necessary. I've NOT done this nor have I priced-out the machine work but list price on 2 shafts & 2 gears is just over $ 200.-- for my 725 gear box. I would think that new keyways would be considerably less, especially if you have a machinist friend. Just a thought. John(ri)

Another thought is to have a custom shaft made, but put a shallow taper on the end with the clutch drum. A taper along with the woodruff key would guarantee it'd never come loose again. Hmm...sometimes I think too much.[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]

Is there a common list of parts that should be replaced if I overhaul it? Is there an overhaul kit?[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]
