Timing Chain: Service and Repair

Removal Procedure

Notice: Do not reuse the engine front cover. Oil leaks may result.

1. Remove the engine front cover.





2. Remove the crankshaft position sensor reluctor ring.

Notice: In the engine install a bolt with the same threads as the crankshaft, but do not use the crankshaft balances bolt or a bolt longer than 1 inch, in the crankshaft. Failing to do so will cause damage to the bolt threads and the crankshaft threaded hole when removing the bolt.

3. Install a 7/16-20 x 1 inch bolt into the end of the crankshaft.





Notice: Align the timing marks before removing the timing chain. If it is necessary to turn either the camshaft or the crankshaft with the timing chain removed, loosen or remove the valve rocker arms. Turning either the crankshaft or camshaft with the timing chain removed may cause the pistons to contact the valves, resulting in damage.

4. Rotate the crankshaft until:
1. The timing marks on both sprockets line up.
2. The number four cylinder is at Top Dead Center (TDC) of the compression stroke.
5. Remove the timing chain and sprockets.
6. Clean and inspect the timing chains and sprockets.

Installation Procedure
1. Install the timing chain and sprockets.
2. Remove the bolt used for rotating the engine from the crankshaft.
3. Install the engine front cover.
