The Multiquip 8972272861 is a genuine OEM Injection Pump Shim DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement sourced through Multiquip's authorized parts network, this shim delivers the exact thickness specification required to maintain correct injection pump timing on the Isuzu 4LE2 engine. Proper fitment is confirmed for DCA25USI series units, so you can order with confidence knowing this is the right part for the job.
Key Features
- OEM-Spec Thickness Tolerance — Manufactured to the exact dimensional tolerance required for correct injection pump positioning on the Isuzu 4LE2 engine, ensuring timing accuracy is not compromised.
- Direct Drop-In Replacement — Matches the original shim profile and seating surface, fitting into the injection pump mounting stack without any machining or adjustment to surrounding components.
- Confirmed Fitment for DCA25USI — Specifically matched to the DCA25USI ultra-silent diesel generator platform running the Isuzu 4LE2 engine.
- Protects Injection Pump Integrity — A correctly shimmed injection pump maintains consistent fuel delivery pressure and injection timing, supporting stable power output and efficient fuel consumption across generator load cycles.
- Fuel System Safety Compliance — Correct shim specification prevents pump misalignment that can lead to fuel system stress, irregular injection events, or premature pump wear on diesel-powered equipment.
An injection pump shim is a precision spacer used to set the correct axial or vertical positioning of the fuel injection pump relative to the engine block. On the Isuzu 4LE2 engine found in the DCA25USI generator, this shim controls the alignment and engagement depth of the pump drive, which directly affects injection timing and fuel delivery consistency. If the shim is missing, worn, or of incorrect thickness, injection timing shifts out of specification — leading to hard starting, increased exhaust smoke, loss of power, or accelerated pump wear.
