For the Perkins 1106.

Applies to: Perkins 1106

Before you start

  • When step 9 is complete, do not rotate the crankshaft until the fuel injection pump is installed on the engine.

Procedure

  1. Set the number one piston at the top center piston on the compression stroke.
  2. Remove the number two fuel injection nozzle.
  3. Ensure that the seat washer for the fuel injection nozzle is removed.
  4. Check the bore of the fuel injection nozzle and check the seat for the fuel injection nozzle.
  5. Align alignment pin (2) of main body (3) to the slot in the fuel injection nozzle hole.
  6. Place main body (3) into the fuel injection nozzle hole and install gland nut (1).
  7. Apply clean engine oil to probe (4).
  8. Insert probe (4) into main body (3). Then, gently lower probe (4) onto the piston crown.
  9. Rotate the crankshaft clockwise until the machined face of the probe (7) aligns with the top of the main body (5).
  10. The number one piston is at four degrees after top center compression stroke.
  11. Remove probe (4) from main body (3).
  12. Remove gland nut (1).
  13. Remove the main body (3) from the cylinder head.
  14. Replace the fuel injection nozzle.
