Note: Careful handling is required for fractured connecting rods. Fractured faces for the connecting rod and connecting rod cap should not be placed on any surface. The connecting rod and the connecting rod cap should be placed on the sides in order to prevent damage. When possible, the connecting rod and the connecting rod cap should be bolted together in order to prevent damage.

Note: Place an identification mark on all connecting rod caps (2). Connecting rod caps (2) should be marked with the corresponding cylinder number.

1. Remove connecting rod caps (2) and connecting rod bearings (1).

   Note: Crankshaft main bearing caps (4) are marked with the numbers 1 through 7. Crankshaft main bearing caps (4) that are not marked should be marked with the corresponding cylinder number. Put the corresponding cylinder numbers on the right-hand side of crankshaft main bearing cap (4).

2. Remove crankshaft main bearing caps (4) and the lower half of crankshaft main bearings (5).

3. Remove crankshaft thrust bearings (3).

4. Attach Tooling (A) and a suitable lifting device to crankshaft (6). The weight of crankshaft (6) is approximately 129 kg (285 lb).

5. Remove crankshaft (6) and the upper half of the crankshaft main bearings.

Installation Procedure

1. Install crankshaft (6) in the reverse order of removal.

   Note: The thrust plate is used on the number 4 crankshaft main bearing only.

   1. Position crankshaft main bearing caps (4) with the part numbers toward the right-hand side of the cylinder block. Position crankshaft main bearing caps (4) in a numerical sequence.

      Note: Use new bolts for the installation of bearing caps (4).

   2. Apply clean "SAE 30W" oil or molybdenum grease to the bolt threads and the washers. Install the bolts. Tighten the bolts to a torque of 150 ± 5 N·m (111 ± 4 lb ft). Place an index mark on each bolt head. Turn the bolts for an additional 60 ± 5 degrees (1/6 turn).

   3. Check the end play of the crankshaft with Tooling (B). The end play must be 0.10 to 0.50 mm (0.004 to 0.020 inch).

   4. Apply clean engine oil to the connecting rod cap bolts. Install the connecting rod cap bolts. Tighten the connecting rod cap bolts to a torque of 130 ± 7 N·m (95 ± 5 lb ft). Place an index mark on each bolt head. Tighten each bolt for an additional 60 ± 5 degrees (1/6 turn).
