The Multiquip 1666151650 Injection Pump Cover is a genuine OEM component designed for the DAW-500S diesel arc welder. As a direct OEM replacement, this cover is manufactured to the same specifications as the original part, ensuring a proper fit on DAW-500S equipment. Sourced through Multiquip's authorized parts network, the part is the correct part to specify when servicing or restoring your diesel welder's fuel system. If your existing cover is cracked, damaged, or missing, this is the part that brings the assembly back to its original condition.
Key Features
- Genuine OEM Construction — Manufactured to original equipment specifications, ensuring correct material thickness and dimensional accuracy for a proper seal over the injection pump assembly.
- Direct Drop-In Replacement — Mounts directly to the injection pump housing on DAW-500S models using existing hardware, with no additional modification to the fuel system required.
- DAW-500S Fitment Confirmed — Verified for use on the Multiquip DAW-500S diesel arc welder, so you can order with confidence that this is the correct cover for your machine.
- Fuel System Protection — Shields the injection pump from contamination, debris, and moisture exposure that can compromise fuel delivery accuracy and shorten pump service life.
- Supports Proper Fuel System Integrity — A damaged or missing injection pump cover exposes precision fuel components to conditions that can lead to premature pump failure; replacing it promptly preserves the pump's operating environment.
The injection pump cover serves as a protective housing component for the diesel fuel injection pump, guarding its precision internals against dust, dirt, and moisture that are common on active job sites. Without an intact cover, the injection pump is exposed to contaminants that can accelerate wear on its finely toleranced components, leading to rough running, poor fuel delivery, and eventual pump failure. Keeping this cover in good condition is a straightforward step that protects one of the most costly components in the diesel fuel system.
