Good To Know

Q: Why is the distributor gear material important? A: The gear material must match the camshaft type, as using a hardened steel gear on a cast iron cam can cause catastrophic gear wear.

Q: How is a 0.500-inch shaft diameter verified on a distributor? A: One can measure the distributor shaft diameter at the gear mounting location using a precision caliper before purchasing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
