Key Features
- OEM-Specified Injection Shim Thickness — Manufactured to the exact dimensional tolerances required for proper injector protrusion depth on the 4LE2 engine, ensuring accurate fuel metering and combustion efficiency.
- Direct-Fit for DCA25USI Generators — Engineered specifically for the DCA25USI ultra-silent diesel generator platform; installs directly into the injection pump assembly without modification.
- Correct Fuel Injection Timing — The right shim thickness is critical to maintaining injection timing; an incorrect or worn shim can cause hard starting, rough running, and elevated emissions on the 4LE2 engine.
- Genuine Multiquip OEM Part — Part 8972272841 is a genuine OEM component supplied through Multiquip's authorized parts network, carrying the full confidence of factory-sourced quality for this engine application.
- Fuel System Integrity — Using the correct OEM shim preserves the calibrated fuel injection pressure and spray pattern, protecting injector seats and pump components from premature wear.
An injection pump shim is a precision-ground spacer used to set the correct height and protrusion of the fuel injector within the injection pump assembly on diesel engines such as the Isuzu 4LE2 found in the DCA25USI. By controlling this measurement with extreme accuracy, the shim ensures that fuel is delivered at the right pressure and at precisely the right moment in the combustion cycle. When a shim is worn, incorrectly sized, or missing, the result can be poor fuel atomization, loss of power, increased fuel consumption, difficult starting, and potential long-term damage to injector components.
