Removal of Lower Timing Chain

1. Drain coolant by removing the cylinder block drain plug and opening the radiator drain cock (Refer to MA section of the Service Manual).

2. Drain engine oil.

3. Remove the oil pan (Refer to "Removal" under "Oil Pan" in the Service Manual).

5. Set # 1 piston at TDC on its compression stroke.

6. Remove the crankshaft pulley.

7. Remove the oil separator.

8. Remove the front cover.

NOTE:
Engine may need to be lowered to provide clearance for the chain tensioner housing of the timing cover to clear the frame. Engine height may need to be adjusted when removing the cover.

CAUTION:
Be careful not to tear or damage the cylinder head gasket.

9. Remove the following parts:

^ Lower timing chain tensioner (push piston in and insert a suitable pin into the hole).
^ Chain tension arm.
^ Lower timing chain guide.

10. Remove the upper timing chain (refer to "Removal of Upper Timing Chain" in this bulletin).
