Tools Required

1. Remove the camshaft cover. Refer to Camshaft Cover Replacement .
2. Remove the intake and the exhaust camshaft sprocket bolts.



3. Install the J 44222 onto the cylinder head and adjust the horizontal bolts into the camshaft sprockets in order to maintain chain tension and keep from disturbing the timing chain components.
4. Carefully move the sprockets with the timing chain, off of the camshafts.
5. Remove the camshaft cap bolts.




Important: Place the camshaft caps in a rack to ensure the caps are installed in the same location from which they were removed.

6. Remove the camshaft caps and store.



7. Remove the camshafts.

1. Coat the camshaft journals, camshaft journal thrust face, and camshaft lobes with clean engine oil.



2. Install the intake and exhaust camshafts to their original positions.
3. Install the J 44221 with the camshaft flats up and the number 1 cylinder at top dead center.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Install the camshaft caps onto their original locations. The camshaft caps are pin stamped for direction and numerical order.

4. Install the camshaft caps and bolts.

Tighten
Tighten the camshaft cap bolts to 12 N·m (106 lb in).

5. Remove the J 44221 .



6. Carefully move the sprockets back onto the camshafts and remove the J 44222 .
7. Install the intake camshaft sprocket washer and bolt, and the exhaust camshaft actuator bolt.

Tighten

•	Tighten the intake camshaft sprocket bolt the first pass to 20 N·m (15 lb ft).

•	Use the J 36660-A to tighten the intake camshaft sprocket bolt the final pass an additional 100 degrees.

•	Tighten the exhaust camshaft actuator bolt the first pass to 25 N·m (18 lb ft).

•	Use the J 36660-A to tighten the exhaust camshaft actuator bolt a final pass an additional 135 degrees.
