Camshaft Gear/Sprocket: Specifications









Install a NEW CMP actuator solenoid valve (234). With the CMP actuator properly positioned onto the camshaft, the CMP actuator solenoid valve can be threaded completely into the camshaft using light hand pressure. Tighten by hand until snug.





Inspect the sprockets for proper alignment. The mark on the CMP actuator sprocket (1) should be located in the 6 o'clock position and the mark on the crankshaft sprocket (2) should be located in the 12 o'clock position.




Tighten the CMP actuator solenoid valve a first pass to 65 Nm (48 lb ft).

Tighten the CMP actuator solenoid valve a final pass an additional 90 degrees using the J 45059 - angle meter.
