The Multiquip 9812250570 Pinion is a genuine OEM component designed for the DCA series ultra-silent diesel generators, including the DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSIU-GEER, DCA25SSAI, DCA45SSIU2, DCA45SSIU2-GEER, DCA45SSIU2-FEMA, DCA60SSI2, and DCA60SSAI. As a direct Multiquip OEM part, the part is manufactured to the same specification as the original component, ensuring correct mesh engagement and dimensional accuracy within the gear train. Confirm your model code against the fitment list above before ordering to ensure this is the correct pinion for your unit. DHS Equipment stocks genuine Multiquip parts so you can get your generator back to full operation without compromise.
Key Features
- Genuine OEM Gear Geometry — Tooth profile and pitch are held to the same tolerances as the factory-installed pinion, ensuring proper mesh with mating gears and preventing premature wear.
- Drop-In Fitment — Engineered to the original shaft interface dimensions, allowing direct installation without machining or shimming adjustments.
- Broad DCA Series Compatibility — Confirmed fit across DCA25SSI, DCA25SSIU, DCA45SSIU2, DCA60SSI2, DCA60SSAI, and related GEER and FEMA variants.
- Sustained Power Output — A correctly functioning pinion maintains smooth, consistent rotational transfer within the drivetrain; a worn or chipped pinion can cause noise, vibration, and generator output instability.
- Backed by Multiquip OEM Supply Chain — Sourced directly through the Multiquip parts network, so material grade and heat treatment match the original specification.
The pinion is a small-diameter toothed gear that meshes with a larger ring gear or rack to transfer rotational force within the generator's mechanical drivetrain. In the DCA series ultra-silent generators, the pinion plays a critical role in translating engine power through the gear assembly to drive the alternator at the correct speed for stable electrical output. When a pinion wears, chips, or loses tooth integrity, the resulting backlash or slippage disrupts the drivetrain, causing erratic frequency output, increased vibration, and — if left unaddressed — damage to surrounding gear components.
