    I pulled a 100 amp alternator of a diesel K5 and hoped to just throw it it but it doesn't charge (did a bench test) Can anyone give me some tips for rebuilding this thing? Is it worth it?
    Thanks,
    David

    How did you bench test it?

    I did a rebuild once, never again. It lasted 1 month and crapped out. Not worth the 15 or dollars to buy it. Just my 2 cents.

    That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>

    Took it to a shop and they ran it to see if it put out current. Mine didn't

    I rebuilt my alt. about a month after I bought my truck, didn't even get the rotor slip rings machined, just slapped it together. Still going strong 4 and a half years later. It'll prolly blow up tomorrow now that I've posted this[​IMG].

    I've rebuilt a couple, assuming the 100amp is the same, it's easy. Go buy a rebuild kit, there aren't many pieces at all, and its cheap. Hardest part is the bearings, they can be removed with a socket set and hammer IIRC : )

    Why insist on counting when the ring gear has the tooth counts stamped in?
