3. Remove the connecting rod cap, noting that corresponding cylinder numbers on the connecting rod and cap are on the same side (1, Fig 14).
4. Lift the connecting rod from the crank pin and withdraw the bearing shells (2, Fig. 14).

INSPECTION
5. Check the crank pin for signs of overheating, scoring or transfer of bearing metal.
6. If the crank pin is suspect in any way, the engine must be removed and the crankshaft rectified, or renewed as necessary.

REFIT
1. Liberally coat the replacement bearing shells with clean engine oil and locate in the connecting rod and cap.
2. Secure the connecting rod cap, ensuring that the marks coincide.
3. Tighten the connecting rod nuts (3, Fig 14) to the correct torque.
4. Repeat operations to change bearings on the remaining five journals.
5. Replace the oil pan.
