The Multiquip 1604052092 Injection Pump Shim is a genuine OEM component designed for DLW400ES series diesel light welder equipment. As a factory-sourced part, it carries the same specifications as the original component installed at the time of manufacture, ensuring an accurate fit within the fuel injection system. This shim is the correct replacement for DLW400ES, DLW400ESA, and DLW400ESA1 models and is sold direct through DHS Equipment as an authorized Multiquip parts distributor.
Key Features
- Genuine OEM Tolerances — Precision-ground to the exact thickness specification required for proper injection pump timing alignment, with no guesswork on shimming stack height.
- Direct Injection Pump Fitment — Seats directly within the injection pump mounting assembly, maintaining the correct pump-to-engine interface without secondary machining or adjustment.
- DLW400ES Series Compatibility — Confirmed fit for DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welders powered by the V1205-B engine.
- Fuel Delivery Precision — A correctly installed shim keeps injection timing within spec, supporting consistent fuel delivery and stable engine output under welding load conditions.
- OEM Part Number Verified — Sourced directly from Multiquip as part number 1604052092, eliminating the risk of incorrect shim thickness from non-verified replacements.
An injection pump shim is a precision spacer used to set and maintain the correct axial position of the fuel injection pump relative to the engine block. By controlling this measurement, the shim ensures that injection timing remains accurate — directly affecting fuel combustion efficiency, engine power output, and smooth operation under load. When a shim is missing, worn, or the wrong thickness, injection timing drifts out of specification, which can result in hard starting, rough running, excessive smoke, or accelerated wear on injection components.
