The Multiquip 8941170322 Crankshaft Assembly is a genuine OEM component designed for DCA40SSAI and DCA40SSI ultra-silent diesel generators. Sourced directly from Multiquip's authorized supply chain, this assembly meets the exact specifications required for these units, ensuring proper fit and function without modification. If you're performing a bottom-end rebuild or replacing a damaged crankshaft, the part is the correct OEM-specified part for the job.
Key Features
- Genuine OEM Crankshaft Specification — Manufactured to the precise dimensional tolerances required for correct bearing journal fit, stroke geometry, and power stroke timing in these diesel generator engines.
- Direct Drop-In Replacement — Engineered to seat correctly within the engine block of DCA40SSAI and DCA40SSI generators, aligning with existing main bearings, connecting rods, and timing components.
- Confirmed Fitment — Compatible with DCA40SSAI and DCA40SSI ultra-silent diesel generator models; verify your model code before ordering.
- Sustained Power Output — A properly functioning crankshaft maintains consistent rotational force transfer from the pistons to the alternator drive, keeping generator output steady under load.
- Critical Engine Integrity — A worn or damaged crankshaft causes excessive vibration, journal wear, and can lead to catastrophic engine failure; replacing with a genuine OEM assembly restores full mechanical integrity.
The crankshaft is the central rotating component of the engine, converting the linear motion of the pistons into the rotational force that drives the alternator and produces electrical output. In a generator application, crankshaft condition directly affects output stability — any imbalance, journal wear, or damage translates into vibration, irregular RPM, and voltage fluctuation. A failed or excessively worn crankshaft will ultimately cause the engine to seize, taking the generator completely out of service until a full bottom-end rebuild is completed.
