Timing Chain: Inspection
- Timing chain deflection (stretch) can be checked for wear before removing front cover. Remove left valve cover. Loosen cylinder No. 5 exhaust rocker arm, and rotate to one side.
- Position dial indicator on end of push rod. Rotate crankshaft clockwise to position cylinder No. 1 at TDC. Ensure crankshaft damper timing mark aligns with TDC mark on timing degree indicator. Zero dial indicator.
- Rotate crankshaft counterclockwise until movement is detected by dial indicator. Note crankshaft damper timing mark for number of degrees of travel from TDC. If reading exceeds 6 degrees, replace timing chain and gears.
