MSD Distributor Drive Gear P/N:8581
MSD 8585 distributor drive gear for the 1981-1996 Ford F-150 V8 5.8L and other vehicles carries camshaft rotation to the distributor.
Worn, chipped or pitted teeth, or metal flakes in the oil, can mean the gear needs replacing. Other ignition or oil-system parts can cause similar trouble, so find the cause first: with the engine off and cool, look at the gear teeth and the camshaft gear they mesh with.
It also fits the 1981-1996 Ford F-250 V8 5.8L and the 1969-1970 Ford Mustang V8 5.8L. The distributor takes a single gear. For another Ford year or engine, look up your own car in the "Vehicles it fits" section.
