Tools Required

1. Remove the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side .
2. Rotate the crankshaft to TDC of the # 1 cylinder compression stroke using the J 43032 the flats machined into the rear of the camshafts should be parallel and facing the cylinder head.



3. Use an open end wrench on the hex cast into the camshaft to aid in the installation of the J 42038 .




Caution: The camshaft holding tools must be installed on the camshafts to prevent camshaft rotation. When performing service to the valve train and/or timing components, valve spring pressure can cause the camshafts to rotate unexpectedly and can cause personal injury.

4. Install the J 42038 to the rear of the camshafts on the right cylinder head.



5. Compress the right secondary drive chain tensioner shoes with your hand.
6. Lock the right secondary drive chain tensioner by inserting a piece of wire (2) into the access hole in the side of the tensioner (1).
7. Slowly release the pressure from the right secondary drive chain tensioner shoes. The tensioner should remain closed.



8. Remove the exhaust camshaft sprocket bolt.
9. Remove the right exhaust secondary camshaft timing sprocket from the camshaft.
10. Clean and inspect the camshaft timing drive components. Refer to Camshaft Timing Drive Components Cleaning and Inspection in Engine Mechanical-3.5L Unit Repair.

1. Position the right secondary camshaft timing components in the following order:

1.1.	Align the intake sprocket drive pin (1) between the two darkened links (2).

1.2.	Align the exhaust sprocket drive pin (4) with the single darkened link (3).

1.3.	Slide the exhaust camshaft sprocket onto the camshaft aligning the drive pin into the camshaft notch.





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.

2. Install the exhaust camshaft sprocket bolt.

Tighten

1. Tighten the camshaft sprocket bolt to 25 N·m (18 lb ft).
2. Use the J 36660-A in order to tighten the camshaft sprocket bolt an additional 45 degrees.



3. Remove the locking wire (2) from the right secondary drive chain tensioner (1) allowing the tensioner shoes to expand and apply pressure to the drive chain.



4. Remove the J 42038 from the right camshafts.
5. Install the right camshaft cover. Refer to Camshaft Cover Replacement - Right Side .
