MSD Distributor Drive Gear P/N:8531
MSD 85833 distributor drive gear for the 1975-1985 Ford F-150 V8 5.0L and other vehicles meshes with the camshaft gear to turn the distributor shaft. It is made for engines with a roller cam, and its low-friction coating process is intended for an easy break-in period.
A worn or chewed gear can show up as wandering ignition timing, a rough-running engine or metal debris on the teeth when the distributor is out. Before you replace the gear, rule out a loose distributor hold-down, a worn cap and rotor or an off ignition timing setting, since each of those can look similar from the driver's seat.
Other fits include the 1980-1985 Ford F-250 V8 5.0L, which takes one gear, and the 1968-1973 Ford Mustang V8 5.0L, along with many more vehicles.
