The Multiquip 1642751010 Injection Pump Assembly D1403 is a genuine OEM component designed for D1403-powered Multiquip equipment. Sourced directly from Multiquip, this assembly carries the exact specifications required to maintain proper fuel delivery and engine performance on D1403 applications. Buyers can order with confidence knowing this is the correct, OEM-matched replacement for that engine family.
Key Features
- OEM-Calibrated Fuel Delivery — Manufactured to the same injection timing and pressure specifications as the original unit, ensuring consistent fuel metering across all load conditions.
- Direct-Mount Replacement — Matches the original mounting pattern and port configuration of the D1403 engine, allowing a straightforward swap without modification to fuel lines or hardware.
- Confirmed D1403 Fitment — Engineered specifically for D1403-series engines used in Multiquip equipment; part number 1642751010 maps directly to this engine family.
- Restores Full Engine Output — A worn or failing injection pump causes rough starting, loss of power, excessive smoke, and uneven idle. Replacing it with this OEM assembly brings combustion efficiency back to spec.
- Fuel System Integrity — Correct injection pump function is critical to safe, stable diesel engine operation; using a genuine OEM assembly eliminates the risk of mis-matched delivery rates that can damage injectors or cause runaway conditions.
The injection pump is the heart of a diesel fuel system — it pressurizes and meters fuel, then delivers precisely timed doses to each injector for combustion. On D1403-powered equipment, a correctly functioning injection pump is what allows the engine to start reliably, run smoothly under load, and maintain consistent power output. When the pump wears internally or fails, symptoms escalate quickly from hard starting and rough idle to black smoke, power loss, and potential injector damage — making prompt replacement with a correctly specified OEM assembly essential to keeping the engine running as designed.
