If you are servicing or calibrating the injection pump on a DCA25USI unit, this is the part your machine was built with.
Key Features
- Injection-System Precision: — Machined to the exact thickness specification required for correct fuel injection pump timing on the DCA25USI 4LE2 engine — even minor shim variance affects fuel delivery and combustion efficiency.
- Direct OEM Replacement: — Installs directly into the injection pump assembly on the DCA25USI without alteration, restoring the pump to its original calibrated position.
- Confirmed DCA25USI Fitment: — Specifically referenced for the Multiquip DCA25USI ultra-silent diesel generator series; verify your model code before ordering.
- Fuel Delivery Accuracy: — A correctly shimmed injection pump maintains proper fuel metering across load conditions, supporting consistent generator output and engine longevity.
- Genuine Multiquip OEM Quality: — Supplied as an authentic Multiquip OEM component, meaning the material grade and dimensional accuracy match the original production part — critical for a high-precision injection system component.
An injection pump shim is a precision spacer used to set the axial position and preload of components within a diesel fuel injection pump. On the DCA25USI 4LE2 engine, the shim establishes the correct clearance and timing geometry inside the pump assembly, directly influencing how and when fuel is delivered to the combustion chamber. If the shim is worn, incorrect, or missing, the injection pump will not operate at its specified timing, which can result in rough running, poor fuel efficiency, excessive smoke, or difficulty starting the generator under load.
