Timing Drive Components





Special Tool(s)

Removal

CAUTION: Since the engine is not free-wheeling, timing procedures must be followed exactly or piston and valve damage may occur.

1. Remove the engine front cover.






2. Remove the crankshaft sensor ring from the crankshaft.






3. Rotate the crankshaft until both camshaft keyways are 90 degrees from the valve cover surface. Make sure the copper links line up with the dots on the camshaft sprocket.






4. Install the special tools on the camshaft.

5. Remove the timing chain tensioning system from both timing chains.
1. Remove the bolts.
2. Remove the timing chain tensioners.
3. Remove the timing chain tensioner arms.

6. Remove the timing chains and crankshaft sprockets.

7. Remove the timing chain guides.
1. Remove the bolts.
2. Remove the LH timing chain guide.
3. Remove the bolts.
4. Remove the RH timing chain guide.

Installation






1. CAUTION: Timing and procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: Do not compress the ratchet assembly. This will damage the ratchet assembly.

Compress the tensioner plunger, using an edge of a vise.






2. Using a small screwdriver or pick, push back and hold the ratchet mechanism.






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






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






5. Remove the tensioner from the vise.






6. If the copper links are not visible, mark one link on one end and one link on the other end, and use as timing marks.






7. Install the timing chain guide.
1. Position LH timing chain guide.
2. Install and tighten the bolts.
3. Position the RH timing chain guide.
4. Install and tighten the RH bolts.

8. NOTE: Crankshaft sprockets are identical. They may only be installed one way. Refer to the following illustration for correct crankshaft sprocket installation.

If removed, install the LH and RH crankshaft sprocketsts

9. CAUTION: Unless otherwise instructed, do not rotate either the crankshaft or the camshafts, when the timing chains are removed and the cylinder heads are installed. Severe piston and valve damage will occur.

NOTE: The number one cylinder is at Top Dead Center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.

Using the special tool, position the crankshaft so the number one cylinder is at TDC.






10. Remove the special tool.

11. Install the timing chains.
^ Install the LH (inner) timing chain on the crankshaft sprocket, aligning the copper link with the dot on the crankshaft sprocket.
^ Install the LH (inner) timing chain on the camshaft sprocket, aligning the copper link with the dot on the camshaft sprocket.
^ Install the RH (outer) timing chain on the crankshaft sprocket, aligning the copper link with the dot on the crankshaft sprocket.
^ Install the RH (outer) timing chain on the camshaft sprocket, aligning the copper link with the dot on the camshaft sprocket.












12. Position the LH and RH timing chain tensioner arm on the dowel pins.






13. Position the RH timing chain tensioner and install the bolts.






14. Position the LH timing chain tensioner and install the bolts.






15. Remove both the RH and LH retaining pins from the timing chain tensioner.

16. Make sure that the copper (marked) chain links are lined up with the dots on the crankshaft sprockets and the camshaft sprocket






17. Remove special tools from the camshaft.






18. Install the crankshaft sensor ring on the crankshaft.
19. Install the engine front cover.
