Tools Required

J 36660-A Torque Angle Meter

1. Remove the engine front cover. Refer to Engine Front Cover Replacement .
2. Align the timing marks on the sprockets so that they are as close as possible.



3. Remove the timing chain damper.
4. Remove the camshaft sprocket bolts.
5. Remove the camshaft sprocket and the timing chain.

Important: If the sprocket does not come off easily, a light blow on the lower edge of the sprocket with a plastic mallet should dislodge the sprocket.

6. Remove the crankshaft sprocket.
7. Clean the timing chain.
8. Clean the sprockets.
9. Inspect all of the components for wear and/or damage.
10. If the pistons have been moved in the engine, use the following procedure:

10.1.

Turn the crankshaft so that the number one piston is at top dead center.

10.2.

Turn the camshaft so that, with the sprocket temporarily installed, the timing mark is straight down.

1. Install the crankshaft sprocket.



2. Assemble the timing chain on the sprockets with the timing marks as close together as possible.



3. Install the timing chain and sprocket.
4. Install the camshaft sprocket bolts.

Tighten
Tighten the bolts to 100 N·m (74 lb ft). Use J 36660-A in order to rotate the bolts an additional 90 degrees.

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.

5. Install the timing chain damper.

Tighten
Tighten the damper bolt to 22 N·m (16 lb ft).

Important: Rotate the engine two revolutions and check the timing marks. Ensure that the marks are aligned.

6. Install the engine front cover. Refer to Engine Front Cover Replacement .
