The Multiquip 8972272881 is a genuine OEM Injection Pump Shim DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a factory-sourced component, this shim delivers the exact dimensional tolerancing required to correctly position the injection pump within the Isuzu 4LE2 engine system. Proper shim specification is critical to fuel injection timing, and this part ensures the pump is set to the manufacturer's intended alignment from the moment it is installed. Contractors and rental fleet operators running the DCA25USI can order with confidence knowing this is the correct OEM part for that application.
Key Features
- Exact OEM Dimensional Tolerance — Manufactured to the precise thickness specification required for correct injection pump positioning on the Isuzu 4LE2 engine, where even minor deviations affect timing accuracy.
- Direct-Fit Installation — Seats into the injection pump mounting interface of the DCA25USI without rework, matching the original component geometry exactly.
- DCA25USI Fitment Confirmed — Specifically validated for the Multiquip DCA25USI ultra-silent diesel generator equipped with the Isuzu 4LE2 engine.
- Protects Injection Timing Integrity — Correct shim thickness keeps fuel delivery timing within specification, sustaining power output consistency and efficient combustion across load cycles.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip OEM part, ensuring full traceability and compatibility with the DCA25USI's engine assembly.
An injection pump shim is a precision spacer used to set the exact axial position of the fuel injection pump relative to the engine block. On the Isuzu 4LE2 engine found in the DCA25USI, this shim controls the depth at which the pump drive engages, which directly determines injection timing. If the shim is the wrong thickness, worn, or missing entirely, injection timing will drift — causing hard starting, uneven power delivery, increased fuel consumption, and potential long-term engine damage. Using the correct OEM shim during pump installation or service is essential to restoring the engine to its designed operating parameters.
