- Install the
J 44221
with the camshaft flats up and the number 1 piston
at top dead center. The crank pin will be at 12 o'clock when the number 1 piston is at top dead center.
- Install the crankshaft sprocket (1).
- Install the intake camshaft sprocket into the timing chain. Refer to
Camshaft Position Actuator Diagnosis
.
- Align the dark link of the timing chain with the timing mark on the intake camshaft sprocket (1).
- Feed the timing chain down through the opening in the head.
- Install the timing chain on the crankshaft sprocket. Align the dark link of the timing chain with the timing mark on to the crankshaft sprocket.
Important: It may be necessary to remove
J 44221
to rotate and hold the camshaft (hex) to align the pin to the camshaft sprocket.
- Install the intake camshaft sprocket onto the intake camshaft.

- Install the exhaust camshaft actuator into the timing chain.
- Align the dark link of the timing chain with the timing mark on the exhaust camshaft actuator (1).
Important: It may be necessary to remove the
J 44221
to rotate and hold the camshaft hex to align the pin to the camshaft sprocket.
- Install the exhaust camshaft actuator onto the exhaust camshaft.
Notice: The camshaft actuator must be fully advanced during installation. Engine
damage may occur if the camshaft actuator is not fully advanced.
Important: Rotate the camshaft actuator clockwise relative to the camshaft prior to tightening the bolt.
- Install the exhaust camshaft actuator bolt.
