The recommended torque spec for Cummins ISX rod bearings is as follows:
The main bearings secure the crankshaft to the engine block. The ISX uses a bedplate design (a lower block girdle) rather than individual main caps. This requires a very specific sequence and torque pattern. cummins isx main and rod bearings torque specs
Place bearings dry on the backside (steel shell) and lubricated on the face (babbit side). Lubricate bolt threads and bolt head flanges. The recommended torque spec for Cummins ISX rod
The rod bearings connect the crankshaft to the pistons. The ISX uses a fractured-split connecting rod design. Never reuse ISX rod bolts. cummins isx main and rod bearings torque specs
