TOOL REQUIRED
^ J 36660 Torque Angle Meter

REMOVAL
1. Remove the front cover.





2. Align the timing marks on the sprockets so that they are as close together as possible.
3. Remove the timing chain dampener.





4. Remove the camshaft sprocket bolt.
5. Remove the camshaft sprocket and chain.
6. Remove the crankshaft sprocket.
7. Inspect the timing chain.
8. Inspect the sprockets.
9. Inspect all components for wear and/or damage.

INSTALLATION
1. If the pistons have been moved in the engine use the following steps:
a. Turn the crankshaft so that the number one piston is at top dead center.
b. Turn the camshaft so that with the sprocket temporarily installed, the timing mark is straight down.
2. If the balance shaft timing has been disturbed refer to balance shaft.
3. Assemble the timing chain on the sprockets with the timing marks in their closest together position.

CAUTION: This bolt is designed to permanently stretch when tightened. The correct part number fastener must he used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

5. Install the camshaft sprocket bolt. Tighten the bolt to 100 Nm (74 ft. lbs.). Use the Torque Angle Meter in order to rotate the bolt an additional 90 degrees.
6. Install the timing chain dampener.
7. Install the timing chain dampener bolt. Tighten the bolt to 22 Nm (16 ft. lbs.).
8. Install the front cover.
