1. Install J 44221 with the camshaft flats up and the number 1 cylinder at top dead center.
2. Compress the tensioner and lock in place.
3. Install the crankshaft sprocket.
4. Install the intake camshaft sprocket into the timing chain.
5. Align the (dark) link of the timing chain with the timing mark on the intake camshaft sprocket (1).
6. Feed the timing chain down through the opening in the head.
7. Install the timing chain onto the crankshaft sprocket. Align the (dark) link of the timing chain with the timing mark on the crankshaft sprocket (2).
Important: It may be necessary to remove J 44221 to rotate and hold the camshaft (hex) to align the pin to the camshaft sprocket
8. Install the intake camshaft sprocket onto the intake camshaft.
Notice: Refer to Fastener Notice in Service Precautions.
9. Install the intake camshaft sprocket washer and new bolt.
^ Tighten the new intake camshaft sprocket bolt the first pass to 20 Nm (15 ft. lbs.).
^ Use J 36660-A to tighten the intake camshaft sprocket bolt the final pass an additional 100 degrees.
10. Install the exhaust camshaft actuator into the timing chain.
11. 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 J 44221 to rotate and hold the camshaft (hex) to align the pin to the camshaft
Notice: The camshaft actuator must be fully advanced during installation.Engine damage may occur if the camshaft actuator is not fully advanced.
12. Install the exhaust camshaft actuator onto the exhaust camshaft.
13. Install the new exhaust camshaft actuator bolt. Tighten
^ Tighten the new exhaust camshaft actuator bolt the first pass to 25 Nm (18 ft. lbs.).
^ Use J 36660--4 to tighten the exhaust camshaft actuator bolt the final pass an additional 135 degrees.
14. Unlock the tensioner.
15. Remove J 44221.
Important: Rotate the camshaft actuator clockwise relative to the camshaft prior to tightening the bolt
