1. Put No. 1 piston at top center on the compression stroke. Make reference to FINDING TOP CENTER COMPRESSION POSITION FOR NO. 1 PISTON. Remove the 3/8"-16 NC bolt from the flywheel. Turn the flywheel approximately 30° clockwise, as seen from the flywheel end.
2. Remove plug (1). Put the 3P1544 Pin in the hole for plug (1). Turn the flywheel slowly counterclockwise, as seen from the flywheel end, until the pin goes into the notch in the injection pump camshaft.
Put the 3/8"-16 NC bolt in the timing hole in the flywheel housing. If the bolt can be installed in the hole in the flywheel, the timing of the fuel injection pump is correct. If it can not be installed see INJECTION TIMING ADJUSTMENT (ON ENGINE).
If the timing is not correct, do the steps that follow:
1. Remove plug (1) from the front cover.
2. Install assembled tooling in the timing gear housing and tighten the locks to hold the tooling in place.
PULLER TOOLING - 2. FT1537 Socket. 3. FT1538 Fuel Pump Timing Gear Puller. 4. 5P8676 Extension
3. Turn the extension counterclockwise to loosen the bolt in the timing gear. As the bolt is loosened it will push against the assembled tooling and push the shaft of the pump drive through the timing gear to loosen the timing gear on the shaft.
4. Turn the flywheel clockwise, as seen from the flywheel end, at least 30° beyond the point where the 3/8"-16 NC bolt can be installed.
5. Tighten the bolt that holds the fuel pump drive gear finger tight. Turn the flywheel counterclockwise, as seen from the flywheel end, until the 3/8"-16 NC bolt can be installed in the flywheel.
6. Tighten the bolt that holds the fuel pump drive gear to 108 ± 5 lb. ft. (149 ± 7 N·m).
7. Remove the pin and bolt. Turn the flywheel two complete revolutions counterclockwise, as seen from the flywheel end. If the bolt and pin can be installed, the on engine timing is correct.
If the bolt and pin can not be installed, do steps 1 through 7 again.
