Injection Pump Timing

NOTE: Before adjusting injection timing, push in cold start device completely.
  1. Remove plug from injection pump cover. Install adapter (2066) and dial gauge (US 1026) to 0-.118 in. (0-3 mm) in place of plug. Preload gauge to about .097 in. (2.5 mm).
  2. Turn engine slowly counterclockwise until gauge needle stops moving. Zero gauge. Turn engine clockwise until TDC mark on flywheel is aligned with boss on bell housing.
  3. If adjustment is necessary, slighty loosen bolts on pump mounting plate. Turn pump to get correct dial gauge reading. Tighten bolts. Recheck injection timing.
  4. When reinstalling plug, torque to 10-14 ft. lbs. (14-20 N.m) with copper seal (Reddish/Brown in color) or 14-18 ft. lbs. (20-24 N.m) with bronze seal (Yellow/Brown in color).
CAUTION: To avoid fuel leaks, always replace plug seal.
