Required Tools 
Tool  Part Number  Part Name  Qty 
A(1)  9U-6198  Crankshaft Turning Tool 
A(2)  9U-7336  Housing 
5P-7305 Engine Turning Tool 
8T-3052  Degree Wheel 
(1) The Crankshaft Turning Tool is used on the front pulley.
(2) This Tool is used in the aperture for the electric starting motor.

Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.



NOTICE

Discard all used Connecting Rod Bolts.


  1. Inspect the pins of the crankshaft for damage. If the crankshaft is damaged, replace the crankshaft. Refer to Disassembly and Assembly, "Crankshaft - Remove" and Disassembly and Assembly, "Crankshaft - Install". Ensure that the bearing shells are clean and free from wear or damage. If necessary, replace the bearing shells.

  2. Install the upper bearing shell (4) into connecting rod (5). Ensure that the locating tab for the upper bearing shell is correctly seated in the slot in the connecting rod.

    Note: The ends of the upper bearing shell must be centered in the connecting rod. The ends of the upper bearing shell must be equally positioned in relation to the mating faces of the connecting rod.

  3. Lubricate upper bearing shell (4) with clean engine oil.

  4. Use Tooling (A) to rotate the crankshaft until the crankshaft pin is at the bottom dead center position.

  5. Carefully pull connecting rod (5) against the crankshaft pin.

    Note: Do not allow the connecting rod to contact the piston cooling jet.

  6. Clean connecting rod cap (2). Install lower bearing shell (3) into connecting rod cap (2). Ensure that the locating tab for the lower bearing shell is correctly seated in the slot in the connecting rod cap.

    Note: The ends of the lower bearing shell must be centered in the connecting rod cap. The ends of the lower bearing shell must be equally positioned in relation to the mating faces of the connecting rod cap.

  7. Lubricate the pin of the crankshaft and lubricate lower bearing shell (3) with clean engine oil.

    Bolt (1a) are Torx
    Bolt (1b) are Bi-Hex

  8. If bolts (1a) were removed, new bolts (1a) must be installed.

    If bolts (1b) were removed, new bolts (1b) must be installed.

  9. Install connecting rod cap (2) to connecting rod (5).

    Note: Ensure that etched Number (X) on connecting rod cap (2) matches etched Number (X) on connecting rod (5).Ensure the correct orientation of the connecting rod cap. The locating tab for the upper bearing shell and the lower bearing shell should be on the same side.

  10. Install new bolts (1a) or (1b) to the connecting rod. Tighten the bolts evenly to a torque of 18 N·m (13 lb ft).

    Note: Do not reuse the old bolts to secure the connecting rod cap.

  11. Tighten bolts (1a) evenly to a torque of 40 N·m (30 lb ft).

    Turn bolts (1a) through a further 120 degrees. Use Tooling (B) to achieve the correct final torque.

  12. Tighten bolts (1b) evenly to a torque of 70 N·m (52 lb ft).

    Turn bolts (1b) through a further 120 degrees. Use Tooling (B) to achieve the correct final torque.

  13. Ensure that the installed connecting rod assembly has tactile side play. Rotate the crankshaft to ensure that there is no binding.

  14. Repeat Steps 2 through 13 for the remaining connecting rod bearings.

    Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 6, 2 with 5 and 3 with 4. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders. Refer to Disassembly and Assembly, "Connecting Rod Bearings - Install" for the correct procedure.

  15. If the glow plugs were removed, install the glow plugs. Ref to Disassembly and Assembly, "Glow Plugs - Remove and Install" for the correct procedure

End By:

  1. Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install" for the correct procedure.
