The front clutch on my 620 went out last night, what's out there for new/used, and what are the going prices?

hmm.. just stopped ? Check for a broken wire. Most electric clutches draw about 3 1/2 to 4 amps of current. I've rewired a few,not hard but a long afternoon's labour. Only cost was $10 of copper wire and $5 for the 5 minute epoxy.

It's not the electrical part of the clutch that's bad, it's one of the spring steel alignment fingers that broke.

It can probably be fixed. Tracy

I have already tack welded it once, I would hate to put too much on it and throw the balance off and wreck something else.

Darrell, it is riveted at each end? I don't remember how that clutch looks at moment. Lots of them can be fixed with proper procedure. HTH Tracy
