Note: Discard all old connecting rod fasteners.
1. Inspect the crankshaft pin for damage. If the crankshaft is damaged, replace it. For correct procedures, see Disassembly and Assembly, "Crankshaft - Removal" and Disassembly and Assembly, "Crankshaft - Installation". Ensure the bearing shells are clean and free from wear or damage.
Replace the bearing shells if necessary.
Note: If the bearing shells were replaced, check that an oversized bearing shell was previously installed.
2. Install the upper bearing shell (4) onto the connecting rod (5). Ensure the locating tab of the upper bearing shell is properly seated in the groove of the connecting rod.
Note: Both ends of the upper bearing shell must be centered on the connecting rod. The distance between the two ends of the upper bearing shell and the mating surface of the connecting rod must be equal.
3. Lubricate the upper bearing shell (4) with clean engine oil.
4. Using tool (A), rotate the crankshaft until the crankshaft pin is at bottom dead center.
5. Carefully pull the connecting rod (5) against the crankshaft pin.
Note: Do not allow the connecting rod to contact the piston cooling nozzle.
6. Clean the connecting rod cap (2). Install the lower bearing shell (3) onto the connecting rod cap (2). Ensure the locating tab of the lower bearing shell is correctly seated in the groove of the connecting rod cap.
7. Lubricate the crankshaft pin and lower bearing shell (3) with clean engine oil.
8. Install the connecting rod cap (2) onto the connecting rod (5).
Note: Ensure the etched number on the connecting rod cap (2) position (X) matches the etched number on the connecting rod (5) position (X). Ensure the connecting rod cap is facing correctly. The locating tabs of the upper and lower bearing shells should be on the same side.
Note: Do not reuse old bolts to secure the connecting rod cap.
9. Use tool (B) to install the new bolt (1) onto the connecting rod.
10. Tighten the bolts evenly to a torque of 40 N·m (30 lb ft).
11. Turn the bolts 120 degrees clockwise. Use tools (B) and (C) to obtain the correct final torque.
12. Ensure there is a tangible backlash after the connecting rod assembly is installed. Rotate the crankshaft to ensure there is no jamming.
13. Repeat steps 2 through 11 to install the remaining connecting rod bearings.
Note: If all connecting rod bearings need to be replaced, this procedure can be performed simultaneously on two cylinders. This procedure can be performed simultaneously on the following cylinder pairs: 1 and 6, 2 and 5, and 3 and 4. Ensure both pairs of connecting rod bearings are installed before switching from one pair of cylinders to the other. For correct procedures, see Disassembly and Assembly, "Connecting Rod Bearings - Installation".
14. If the glow plugs were removed, install them. For the correct steps, please refer to Disassembly and Assembly, "Glow Plugs - Removal and Installation".
