The Multiquip 8972272871 is a genuine OEM Shim Injection Pump DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator series. As a factory-sourced component, this shim is manufactured to the exact tolerances required by the fuel injection system on the 4LE2-powered DCA25USI, ensuring the injection pump seats and operates precisely as intended. DHS Equipment stocks this part to keep your generator running at full rated output with no guesswork on fitment. Confirm your model code against your unit before ordering to ensure an exact match.
Key Features
- OEM-Spec Injection Tolerance — Manufactured to the precise thickness specification required to correctly position the injection pump on the 4LE2 engine, maintaining proper fuel delivery timing.
- Direct-Fit Installation — Designed to drop into the DCA25USI injection pump mounting location without machining or shimming adjustments beyond what the OEM service procedure calls for.
- Confirmed DCA25USI Fitment — Validated for the Multiquip DCA25USI ultra-silent diesel generator equipped with the Isuzu 4LE2 engine.
- Fuel System Integrity — A correctly shimmed injection pump maintains accurate fuel metering and injection timing, directly supporting stable power output and efficient fuel consumption from your generator.
- Fuel System Safety Compliance — Using the correct OEM shim ensures the injection pump is seated at the manufacturer-specified depth, preventing misalignment that could lead to fuel leaks or injector damage.
The injection pump shim is a precision spacer that sets the correct axial or mounting position of the fuel injection pump relative to the engine block on the Isuzu 4LE2 diesel. Even a small deviation in shim thickness can alter injection timing, leading to hard starting, uneven power output, excessive smoke, or accelerated wear on injection components. When servicing or replacing the injection pump on a DCA25USI generator, using the correct OEM shim — part 8972272871 — is essential to restoring the fuel system to its original calibration and protecting the long-term health of the engine.
