- Rotate the injection pump shaft until the number 5 (located in the center of number 750) is positioned at 9 o'clock.
- Position injection pump to mounting flange on gear housing while aligning injection pump shaft through back of injection pump gear. Be sure the number 5 is still at the 9 o'clock position.
Bring the engine to TDC position. Do this by rotating the crankshaft until the TDC mark on the crankshaft damper is at 12 o'clock position. It does not matter if cylinder number 1 or number 6 is at TDC. Again, check to be sure the number 5 is still at the 9 o'clock position. Rotate pump shaft accordingly.
