The crankshaft main bearings ensure the crankshaft spins freely while handling the high combustion pressures of the ISX engine. When installing new main bearings and fasteners (bolts): Tighten in sequence to 2nd Step: Rotate all capscrews an additional 180∘180 raised to the composed with power (1/2 turn). Important Notes:
Measure the crankshaft journals using a micrometer to check for out-of-roundness or taper. Inspect for scoring, heat discoloration, or deep ridges.
Adhering to professional best practices is as important as hitting the right torque number.
