Cummins Isx Main And Rod Bearings Torque Specs New //free\\ (HD · 480p)

Using main and connecting rod bearings requires strict adherence to Cummins’ proprietary torque-plus-angle procedure. Unlike old-school engines where you just set a click-type wrench to 150 lb-ft, the ISX uses a torque-to-yield (TTY) methodology, specifically a Torque + Angle specification.

, the procedure requires an initial pre-stretch step that is skipped with used bolts: Industrial Parts Depot Tighten in numerical sequence to 29 ± 4 ft-lb (40 N•m) Loosen the bolts completely in numerical sequence. Retighten in numerical sequence to 52 ± 4 ft-lb (70 N•m) Rotate the bolts an additional 60 ± 5 degrees Main Bearing Torque Specs cummins isx main and rod bearings torque specs new

Do not use a torque wrench for the angle stage. Once you hit 95 lb-ft (or 75 lb-ft on rods), switch to an angle gauge. A torque wrench cannot accurately measure degrees. Using main and connecting rod bearings requires strict
