The Multiquip 1660451650 Injection Pump Cover D1403 is a genuine OEM component designed for equipment powered by the D1403 engine. Sourced directly through Multiquip's authorized parts program, this cover ensures a correct, manufacturer-approved fit on D1403-equipped machines. Whether you're performing scheduled maintenance or replacing a damaged cover, the part delivers the exact form and material integrity the engine was built around.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original cover, ensuring proper sealing against the injection pump housing on the D1403 engine.
- Direct-Fit Replacement — Mounts using the same bolt pattern and interface as the factory cover, with no reworking of mounting surfaces or hardware required.
- D1403 Engine Fitment — Confirmed for use with D1403 engine-powered equipment; always cross-reference part number 1660451650 against your serial tag before ordering.
- Protects Injection Pump Internals — A properly seated injection pump cover shields precision fuel delivery components from contaminants, moisture, and mechanical damage that can compromise injection timing and engine output.
- Fuel System Integrity — A compromised or cracked injection pump cover can allow contamination into the fuel system, leading to injection irregularities and hard starting — replacing it promptly maintains clean, consistent fuel delivery.
The injection pump cover serves as a protective enclosure for the fuel injection pump on the D1403 engine. It seals the pump against dust, debris, and moisture that can degrade the precision components responsible for metering and delivering fuel to the engine's cylinders. When the cover cracks, warps, or loses its seal, contaminants can enter the injection system, causing erratic engine performance, difficult starting, increased fuel consumption, and accelerated wear on internal pump components. Replacing a damaged cover promptly is one of the simplest ways to protect the injection system's long-term reliability.
