Injection Pump Timing
- Check that notch in pump flange is in line with notched line on front plate. Set No. 1 cylinder at TDC of compression stroke. Remove injection pump pulley cover (right half of timing belt cover) to ensure timing marks are aligned. SeeFigure .
- Disconnect injection pipe from pump (using back-up wrench) and remove distributor head screw. Install Timing Gauge Tool (J-29763 or J-28827) and set lift approximately .04" (1 mm) from plunger.
- Turn engine until No. 1 cylinder is 45-60° BTDC. Calibrate dial indicator to zero. Turn crankshaft pulley slightly in both directions and make sure zero reading does not change.
- Turn crankshaft in normal direction of rotation until timing mark (15° BTDC on Federal P'UP, 13° BTDC on Trooper II) on crankshaft pulley is in line with indicator. See Fig 1 . Dial indicator should show .020" (0.5 mm). If not, loosen pump bolts and rotate pump slightly to obtain proper timing.
