Below is the for Cummins ISX (Common Rail – 2007 to 2018) . This does not apply to the newer X15 (2018+) without verification.
The Cummins ISX engine uses a main bearing cap design, which requires specific torque specs for proper tightening. Here are the recommended torque specs for the main bearings:
Install the bearing cap and torque it to spec (you may use old bolts purely for this measurement step). Remove the cap without rotating the crankshaft.
: Tighten in numerical sequence to 30 ft-lb (40 N•m).
