1. Check the connecting rod
alignment If either the bend or the twist exceeds the specified limit,the connecting rod must be replaced. Bend per 100 mm (3.937 inch)
Limit: 0.15 (0.0059)
Twist per 100 mm (3.937 inch)
Limit: 0.20 (0.0078)
2. Measure the connecting rod
thrust clearance. Use a feeler gauge to measure the thrust clearance at the large end of the connecting rod If the clearance exceeds the specified limit, the connecting rod must be replaced. Standard: 0.16 mm - 0.35 mm (0.0063 inch - 0.0138 inch)
Limit: 0.40 mm (0.0157 inch)
3. Measure the oil clearance between the connecting rod
and the crankshaft
- Remove the connecting rod cap nuts and the rod caps (12). Arrange the removed rod caps in the cylinder number order.
- Clean the rod bearings and the crankshaft pins.
- Carefully check the rod bearings. If even one bearing is found to be damaged or badly worn, the entire bearing assembly must be replaced as a set. Reinstall the bearings in their original positions. Apply plastigage to the crank pin.
- Reinstall the rod caps (12) to their original positions. Tighten the rod cap nuts. Torque: 54 Nm (40 ft. lbs.) Note: Do not allow the crankshaft to rotate.
- Remove the rod caps.
- Measure the width of the plastigage and determine the oil clearance. If the oil clearance exceeds the limit, replace the rod bearing as a set. Standard: 0.019 mm - 0.043 mm (0.0007 inch - 0.0017 inch) Limit: 0.08 mm (0.003 inch)
- Clean the plastigage from the bearings and the crankshaft pins.
