Removal

NOTICE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in the crankshaft pulley procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special tools, otherwise severe engine damage may occur. Service and Repair

1. Remove the engine front cover. Service and Repair.

2. Compress the timing chain tensioner in the following sequence.

1. Using a small pick, release and hold the ratchet mechanism.
2. While holding the ratchet mechanism in the released position, compress the tensioner by pushing the timing chain arm toward the tensioner.
3. Insert a paper clip into the hole to retain the tensioner.





3. Remove the 2 bolts and the timing chain tensioner.





4. Remove the RH timing chain guide.





5. Remove the timing chain.





6. Remove the bolts and the LH timing chain guide.





7. NOTICE: Do not rely on the Camshaft Alignment Plate to prevent camshaft rotation. The tool or the camshaft may be damaged.

If necessary, remove the 2 bolts and the camshaft sprockets.

- Use the flats on the camshaft to prevent camshaft rotation.





Installation

1. Remove the Camshaft Alignment Plate.





2. NOTICE: Do not rotate the camshafts. The valves and pistons may be damaged.

If the camshaft sprockets were not removed, use the flats on the camshafts to prevent camshaft rotation and loosen the 2 sprocket bolts.





3. If removed, install the camshaft sprockets and the bolts. Do not tighten the bolts at this time.





4. Install the LH timing chain guide and the bolts.





5. Install the timing chain.





6. Install the RH timing chain guide.





NOTE: If the timing chain plunger and ratchet assembly are not pinned in the compressed position, follow the next 4 steps.

7. NOTICE: Do not compress the ratchet assembly. This will damage the ratchet assembly.

Using the edge of a vise, compress the timing chain tensioner plunger.





8. Using a small pick, push back and hold the ratchet mechanism.





9. While holding the ratchet mechanism, push the ratchet arm back into the tensioner housing.





10. Install a paper clip into the hole in the tensioner housing to hold the ratchet assembly and the plunger in during installation.





11. Install the timing chain tensioner and install the bolts. Remove the paper clip to release the piston.





12. Install the Camshaft Alignment Plate.





13. NOTICE: Do not rely on the Camshaft Alignment Plate to prevent camshaft rotation. The tool or the camshafts may be damaged.

Using the flats on the camshafts to prevent camshaft rotation, tighten the bolts.
- Tighten to 65 Nm (48 lb-ft).





14. Install the front cover. Service and Repair.
