Timing Chain and Sprocket Installation L36

Tools Required

J 36660-A Torque Angle Meter

1. Install the crankshaft balancer key into the crankshaft keyway.

The crankshaft balancer key should be parallel to the crankshaft or with a slight incline.

2. Install the timing chain on the sprockets. Align the timing marks.



3. Install the timing chain, the crankshaft sprocket, and the camshaft sprocket.

Notice: Refer to Special Fastener Notice in the Preface section.

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.

4. Install the camshaft sprocket bolt.

Tighten
Tighten the camshaft sprocket bolt to 100 N·m (74 lb ft). Use J 36660-A to tighten the camshaft sprocket bolt an additional 90 degrees.




5. Install the timing chain dampener.

Tighten
Tighten the timing chain dampener bolt to 22 N·m (16 lb ft).
