Connecting Rod Fitting

Connecting Rod Fitting






• The connecting rod cap bolts (4) should be examined before reuse. Bolt stretch can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2) the bolt (1) must be replaced.






The bearing caps are not interchangeable or reversible, and should be marked (1) during removal to ensure correct reassembly. Cracked bearing caps stay with the cracked rod. The bearing shells must be installed with the tangs inserted into the machined grooves in the rods and caps. Install the cap with the tangs on the same side as the rod. For connecting rod bearing fitting, refer to => [ Connecting Rod Bearing Clearance ] Connecting Rod Bearing Clearance. Fit all connecting rods on one bank until complete.

- Before installing the bolts, the threads should be oiled with engine oil.

- Install the bolts finger tight then alternately tighten each bolt to assemble the cap properly.

- Install the connecting rod cap bolts following this three step torque plus angle method:

• Step 1: Tighten both bolts to 7 Nm (5 ft. lbs).

• Step 2: Tighten both bolts to 28 Nm (21 ft. lbs).

• Step 3: Tighten both bolts an additional 90°.

- Using a feeler gauge, check the connecting rod side clearance. Refer to => [ Connecting Rod and Bearing Specifications ] Connecting Rod and Bearing Specifications.
