Description

Keep the secondary air injection pump turning true with the Dorman - OE Solutions Secondary Air Injection Pump Pulley 300-921. This pulley bolts onto the secondary air injection (smog) pump and accepts the engine's drive belt, transferring rotation from the belt to spin the pump. It's a direct-fit replacement for the listed applications: the 1987-1996 Ford Bronco, E-150 Econoline, E-150 Econoline Club Wagon, E-250 Econoline, F-150, and F-250, plus the 1988-1991 Ford E-250 Econoline Club Wagon.

Drives the pump: provides the belt-driven surface that rotates the secondary air injection pump.
Direct replacement: installs in place of a pulley that has become cracked, bent, or worn.
Restores belt drive: if a damaged original pulley is the cause of belt slip, squeal, or wobble, this part replaces it.

A cracked, distorted, or worn pulley can let the belt slip or run out of true. Inspect the belt and drive components to confirm the pulley is the cause before replacing.
