Injection Pump Timing

NOTE: Before starting timing procedure, check valve timing and drive belt tension. Be sure cold start lever is against stop (toward drive gear on pump).
  1. Set crankshaft to TDC on No. 1 cylinder and align marks on flywheel and clutch housing. Check marks on injection pump sprocket and mounting plate. If timing adjustment is necessary, remove center plug from injection pump cover.
  2. Install adapter (2066) and dial indicator (0-3 mm range) in place of plug. See Fig 1 . Preload dial indicator to .097" (2.5 mm). Slowly turn engine counterclockwise until dial indicator needle stops moving. Zero indicator.

  3. Turn engine clockwise until TDC mark on flywheel lines up with reference mark. Check and compare dial indicator reading with specified lift. See Injection Pump Timing Specifications table. If necessary, loosen bolts on mounting plate and support. Turn pump to adjust timing and tighten bolts. Recheck dial indicator readings.
