Cummins ISX Single Cam Parts – Crankshaft Section

Your ISX Single Cam’s bottom end depends on a straight, balanced crankshaft and a sealed, properly clearanced support system. This catalog groups the core components you’ll stage together when addressing crank, bearing, sealing, and torsional control work on ISX/ QSX platforms.

Start with the new crankshaft (12-bolt nose and 12-bolt flange) designed for precise oiling and stable torque transfer. Pair it with a crankshaft shell (main bearing) set in standard or 0.10 mm oversize to match measured journal sizes after inspection or machining. Typical replacement indicators include low oil pressure at idle, copper showing on shells, metal in the pan, knock under load, or excessive end play.

Seal integrity is handled by front and rear crankshaft seal kits—each includes the seal and sleeve to restore the running surface and curb leaks at the damper and flywheel ends. Reinforce the job with the gear housing gasket, flywheel housing gasket, and front cover seal strips (upper and lower) to eliminate seepage paths around the timing/gear train and bellhousing.

To control torsional vibration and protect the crank, install a 12-bolt vibration damper. Symptoms pointing to damper service include belt flutter, harmonic “buzz” at certain RPMs, accelerated accessory bracket fatigue, or repeated front seal failure.

Round out the package with upper and lower gasket sets (options for engines with or without EGR) so you can button up the top and bottom ends in one maintenance window. Sourcing from Diesel Pro Power means fast, accurate fitment and technician-first support—trusted by 40,000+ satisfied customers—to keep your ISX running smooth and leak-free.
