The Multiquip 1131280180 Pinion is a genuine OEM component designed for the DCA-series ultra-silent diesel generators, including the DCA40SSAI, DCA45SSIU2, DCA60SSAI, and DCA60SSI2. As a direct OEM part, the part is manufactured to the exact tolerances required by Multiquip, ensuring a proper mesh and load transfer within the gear train. Confirmed fitment also extends to DCA45SSIU2-FEMA and DCA45SSIU2-GEER variants, making this the correct choice across multiple DCA configurations. Source the 1131280180 from DHS Equipment for an authorized OEM part backed by verified fitment.
Key Features
- OEM Gear Geometry — Manufactured to the exact tooth profile and pitch specifications of the original Multiquip pinion, ensuring correct mesh engagement and load distribution within the gear drive.
- Drop-In Installation — Engineered to the same shaft interface and dimensional envelope as the original, allowing direct installation without alteration to surrounding components.
- Broad DCA-Series Fitment — Confirmed for DCA40SSAI, DCA45SSIU2, DCA60SSAI, DCA60SSI2, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent generator models.
- Sustained Power Output Integrity — A correctly seated pinion maintains consistent rotational transfer to the generator head, supporting stable voltage and frequency output under load.
- Material Durability — Produced from hardened material stock matched to OEM standards, resisting wear and fatigue under the continuous-duty cycles typical of prime and standby power applications.
The pinion is a small-diameter gear that meshes with a larger mating gear to transmit rotational force and, where applicable, change the speed or torque ratio within a drive train. In a diesel generator, the pinion plays a critical role in transferring drive between engine-side and generator-side components — maintaining consistent rotational speed that directly governs the quality of electrical output. When a pinion wears, chips, or loses proper mesh alignment, the result is increased vibration, audible gear noise, and ultimately irregular power delivery or drivetrain failure. Replacing a worn pinion promptly with a correct OEM part preserves the mechanical integrity of the entire drive assembly.
