ABSTRACT:
Method and apparatus for rebuilding advance weights of a distributor assembly. The apparatus includes a drilling fixture having a hole and a weight-engaging balance pin positioned to one side of the hole, and a stepped pin having a large diameter shank accommodated by the hole in the drilling fixture and a small diameter shank accommodating deformed oblong holes of the advance weights. The method includes positioning the deformed oblong hole of the advance weight on the small diameter shank of the stepped pin establishing the original axis of the original hole, balancing the advance weights against the balance pin, removing the stepped pin, and drilling the deformed oblong holes in the advance weights out to an oversized round hole. Subsequently, the advance weights are reinstalled with a nylon bushing in the bored oversized hole on the pins of the distributor assembly. The apparatus of the drilling fixture and stepped pin can be sold in an over-the-counter kit at auto part stores and repair facilities.
