Procedure

  1. Clean the mating surfaces of the cylinder block and the fuel injection pump.
  2. New shims (3) must be used during assembly. Install the correct thickness and correct number of shims on the mounting face of the cylinder block.
  3. Position fuel injection pump (1) close to the mounting face of the cylinder block, and connect link (6) and fuel rack control (5) with clip (7).
  4. Align fuel injection pump (1) with the studs on the cylinder block. Install the fuel injection pump to the cylinder block.
  5. Install bolts (4) and nuts (2). Ensure that the tube clip for the engine oil line is secured by the appropriate fastener. Evenly tighten bolts and nuts to specified torque.
  6. Install the fuel injection lines.
  7. For engines with a flexible fuel return hose, connect the fuel hose to the inlet connection of the fuel injection pump.
  8. Install the fuel shutoff solenoid.
