Fitting Connecting Rods

FITTING CONNECTING RODS










NOTE: 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) at 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 cap with the tangs on the same side as the rod. For connecting rod bearing fitting Service and Repair. Fit all connecting rods on one bank until complete.





1. Before installing the bolts, the threads should be lubricated with engine oil.
2. Install bolts finger tight then alternately torque each bolt to assemble the cap properly.
3. Tighten the cracked cap bolts to 7 Nm (5 ft.lbs.) initially. Tighten the bolts an additional 21 Nm (15 ft.lbs.) and then turn each bolt 90° to final clamping load.
4. Using a feeler gauge, check connecting rod side clearance. Refer to Engine Specifications Engine Specifications
