The Multiquip 1666116320 Fuel Camshaft Stopper is a genuine OEM component designed for the DAW-500S diesel arc welder. Sourced directly from Multiquip, this stopper is purpose-built to match the original specification, ensuring correct installation and proper operation within the fuel delivery system. If you are servicing or overhauling a DAW-500S welder, the part is the correct OEM part to restore your machine to full working order.
Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional tolerances required by the fuel system on Multiquip diesel arc welders, ensuring correct engagement and retention.
- Direct-Fit for DAW-500S — Engineered specifically for the DAW-500S, this stopper seats and secures exactly as the original component, requiring no modification to the fuel camshaft assembly.
- Fuel System Integrity — A correctly functioning fuel camshaft stopper maintains precise control over fuel delivery timing, which is critical to consistent arc output and engine performance.
- Prevents Camshaft Migration — This stopper locks the fuel camshaft positively in position, preventing unintended movement that can disrupt injection timing and cause rough or inconsistent engine operation.
- OEM Part Number Traceability — Supplied under Multiquip part 1666116320, giving you confidence that the component on hand matches the application listed for the DAW-500S welder.
The fuel camshaft stopper is a retention component within the engine's fuel injection system. Its role is to hold the fuel camshaft securely in its correct axial position so that injection timing remains consistent across every firing cycle. When this stopper wears, becomes damaged, or is missing entirely, the camshaft can shift out of position — throwing off injection timing, degrading combustion efficiency, and causing the engine to run unevenly or lose power output. On a diesel arc welder like the DAW-500S, where stable engine speed is directly tied to consistent weld arc quality, a failed fuel camshaft stopper can compromise both the machine's welding performance and its overall reliability on the job.
