Camshaft: Procedures
STANDARD PROCEDURE - TIMING VERIFICATION
1. Remove the cylinder head cover.
2. Remove fuel injector from cylinder number 1.
3. Remove the crankcase breather from the gear housing cover.
4. Using Special Tool 7471B rotate the engine until the timing mark on the fuel pump gear is aligned with the TDC mark on the gear housing cover.
5. Using a 8 inch 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.
6. With piston number 1 at TDC the timing mark on the fuel pump gear should be aligned with the TDC mark on the gear housing cover. If marks do
not line up, remove the gear housing cover.
7. With cylinder number still at TDC, inspect the keyway on the crankshaft gear for proper alignment (12 o'clock position).
8. If the keyway is not at 12 o'clock position replace the crankshaft gear assembly.
9. If the keyway is at 12 o'clock position, verify timing mark alignment between the camshaft gear, crankshaft gear and the fuel pump gear, if not
aligned inspect keyway on camshaft gear.
10. Inspect keyway on camshaft gear for proper alignment with the key in the camshaft, if alignment is off replace the camshaft/gear assembly.
11. If timing marks alignment is off and no damage is found at either the crankshaft or camshaft gear keyways, realign timing marks as necessary.
