Cummins 4992924 Connecting Rod Assembly

The Cummins 4992924 connecting rod is a critical engine component designed for 3.3 liter B series diesel engines, specifically Tier 3 B3.3 and QSB3.3 models. It transmits combustion force from the piston to the crankshaft, converting reciprocating motion into rotational torque. Manufactured from forged steel, the rod undergoes precision machining and heat treatment to withstand high cyclic loads and thermal stress in construction and industrial duty cycles. This part replaces Cummins OEM references 4944475, 4993829, 4993824, 4956018, 4993830, 4992926, C6204313101, 4993823, and 4956017. Direct replacement installation requires adherence to OEM torque specifications and bearing clearance verification.
