Two hollow dowels (one at 3 o’clock, one at 9 o’clock on the block face) ensure concentricity.
The ISX platform uses a deep-skirt, high-strength cast iron or composite (on some later models) flywheel housing. The housing: Cummins Isx Flywheel Housing Torque Specs

The flywheel housing on a Cummins ISX engine serves as a critical structural link between the engine block and the transmission or driven equipment. Proper torque application on its mounting fasteners is essential to prevent housing distortion, vibration, oil leaks, and catastrophic failure. This paper specifies the exact torque values, sequence, and preparation for all bolts securing the flywheel housing to the cylinder block, as well as ancillary fasteners (e.g., flywheel housing access covers, rear crankshaft seal housing). Adherence to Cummins standard repair practices (STC) and torque-plus-angle methodology is emphasized.
While working on the flywheel housing, you may need these related torque specs:
Torque specifications for the flywheel housing are typically defined in stages: a low-torque step for initial alignment, and a final torque value for all mounting bolts. Attempting to apply the full torque value to an unaligned housing can lead to catastrophic component distortion, increased runout, and premature failure of the rear crankshaft seal.
