The Multiquip 1641452090 is a genuine OEM Injection Pump Shim 0.20MM designed for DAW-500S and DCA10SPX3 series equipment. As a direct OEM component, it is manufactured to the exact thickness and material specification required for proper fuel injection pump timing and alignment. This shim is confirmed to fit DAW-500S welders and DCA10SPX3 diesel-powered generators, making it the correct choice when servicing or rebuilding the injection pump on these units. Sourced directly from Multiquip, part 1641452090 ensures you are installing the right shim the first time.
Key Features
- OEM-Grade Thickness Precision — Manufactured to an exact 0.20MM tolerance, ensuring the injection pump seats at the correct depth for proper fuel delivery and timing.
- Drop-In Fit for Injection Pump Service — Designed to install directly within the injection pump stack on compatible units without alteration or re-machining of mating surfaces.
- Confirmed Fitment — Compatible with DAW-500S arc welders and DCA10SPX3 diesel-powered generators in the Multiquip equipment lineup.
- Critical for Injection Timing Accuracy — Even slight shim variation can affect fuel injection timing and engine performance; using the correct 0.20MM OEM shim restores calibrated operation.
- Fuel System Safety Compliance — Proper shim specification is essential in diesel fuel systems where incorrect tolerances can lead to uncontrolled injection pressure or engine damage.
An injection pump shim is a precision-thickness spacer used to set the correct positioning and preload of the fuel injection pump relative to the engine's timing components. By controlling the exact distance and alignment of the pump, the shim directly influences when fuel is injected into each cylinder — a critical factor in achieving clean combustion, full power output, and efficient fuel consumption. When a shim is worn, damaged, or replaced with an incorrect thickness, injection timing shifts out of specification, which can result in hard starting, rough running, increased exhaust emissions, or long-term engine wear.
