Tools Required

Important: The camshaft drive sprockets have numbered slots that must be aligned with the pins on the camshafts.

When the numbered camshaft drive sprocket slot is properly installed on the camshaft pin, the reference mark near the gear of the drive sprocket, will align with the notch on the engine rear cover (1,2,3,4).
1. Install the camshaft drive sprockets.

Ensure the camshaft pins are installed in the correct numbered slot on the drive sprockets.





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: Use new camshaft drive sprocket bolts, the old bolts are not reusable.

2. Install the camshaft drive sprocket bolts with washers.

Tighten

•	Use the relevant J 42069-1 or the J 42069-2 to hold the camshaft drive sprockets and the camshafts in place while tightening the camshaft drive sprocket bolts.

•	Use the J 36660-A to tighten the camshaft drive sprocket bolts to 50 N·m (37 lb ft) on the first pass, 60 degrees on the second pass and 15 degrees on the third pass.
