SOURCE: i'm looking for the 2000 isuzu rodeo 3.2L v6 connecting rod bearings torque specs.

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.

1. Remove the connecting rod cap nuts and the rod caps (12). Arrange the removed rod caps in the cylinder number order.
2. Clean the rod bearings and the crankshaft pins.
1. 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.
2. 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.
3. Remove the rod caps.
1. 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)
2. Clean the plastigage from the bearings and the crankshaft pins.
