Key Features
- OEM Dimensional Accuracy — Manufactured to the precise thickness specification required for correct injection pump timing and seating on the DCA25USI 4LE2 engine.
- Direct OEM Replacement — Part 8972272821 installs in place of the original shim with no modification to the injection pump mounting or fuel system components.
- Confirmed DCA25USI Fitment — Validated for use on the Multiquip DCA25USI ultra-silent diesel generator series.
- Fuel System Integrity — A correctly shimmed injection pump maintains optimal fuel delivery pressure and timing, directly affecting engine output, efficiency, and consistent generator performance.
- Fuel System Safety Compliance — Proper injection pump shim thickness is critical to preventing fuel delivery imbalance and potential engine damage; using the correct OEM shim eliminates the risk of improper pump positioning.
An injection pump shim is a precisely machined spacer used to set the correct mounting height and alignment of the fuel injection pump on the engine block. On diesel engines like the 4LE2 found in the DCA25USI, even a small deviation in shim thickness can affect injection timing, fuel atomization, and overall engine efficiency. A missing, worn, or incorrectly sized shim can lead to hard starting, uneven power output, increased fuel consumption, or long-term damage to the injection pump and engine components.
