VALVE TIMING
STANDARD PROCEDURE - TIMING VERIFICATION
1. Remove the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) -
REMOVAL).
2. Remove fuel injector from cylindernumber 1 (Refer to 14 - FUEL SYSTEM/FUEL INJECTION/FUEL INJECTOR
- REMOVAL).
3. Using Special Tool 7471B rotate the engine until the TDC mark on the damper is at 12 o’clock.
4. Using a 8 in.x 1/4 in. dowel rod inserted into cylinder number 1, rock the crankshaft back and forth to verify
piston number 1 is at TDC.
5. With cylinder number still at TDC, inspect the keyway on the crankshaft gear for proper alignment (12 o’clock
position).
6. If the keyway is not at 12 o’clock position replace the crankshaft gear assembly.
7. If the keyway is at 12 o’clock position, remove front gear cover and verify timing mark alignment between the
camshaft gear and crankshaft gear, if not aligned inspect keyway on camshaft gear.
8. Inspect keyway on camshaft gear for proper alignment with the key in the camshaft, if alignment is off replace
the camshaft/gear assembly.
9. If timing marks alignment is off and no damage is found at either the crankshaft or camshaft gear keyways,
realign timing marks as necessary.
