Camshaft Gear/Sprocket: Service and Repair

CAMSHAFT SPROCKETS


REMOVAL

CAUTION: When cam sprockets are loosened or removed, the camshafts must be timed to the engine. Refer to camshaft timing and timing belt installation procedure.


1. Hold camshaft sprocket with 36 mm (1 7/16 in.) box wrench loosen and remove bolt and washer. To remove the bolt with engine in the vehicle it may be necessary to lift that side of the engine because the right bolt is 213 mm (8 3/8 in.) long and the left bolt is 255 mm (10.0 in.) long.

2. Remove camshaft sprocket from camshaft. Each sprocket has a D shaped hole that allows it to rotate several degrees in each direction on its shaft. This design must be timed with the engine to ensure proper performance of the engine. Refer to camshaft and timing belt installation.
