  3. 3
    Set dial gauge so its indicator points to somewhere between 1.0 and 2.0 mm (0.039 and 0.079 in) on the scale.
  4. 4
    Turn crankshaft 1 turn clockwise and check that dial gauge indicates the same value again.
  5. 5
    Turn crankshaft counterclockwise about 20 to 25 degrees, then set dial gauge indicator to 0 mm (0 in).
  6. 6
    Turn crankshaft clockwise and set the pump timing mark to the mark on the crankshaft pulley.
    Pump timing mark: Yellow painted mark

  7. 7
    Read plunger lift.
    Plunger lift:
    0.79 - 0.85 mm (0.0311 - 0.0335 in) at pump timing mark

Adjusting

  1. 1
    If plunger lift is not within the specified value, adjust by turning injection pump.
    If indication is smaller than the specified value, turn pump body away from engine.
    If indication is larger than the specified value, turn pump body towards engine.
