The Multiquip 1604052122 Injection Pump V1305-E2B Shim is a genuine OEM component designed for DLW400ES series diesel light welder units. As an authorized Multiquip OEM part, 1604052122 is manufactured to the same tolerances as the original, ensuring correct fuel injection pump alignment on V1305-E2B engine applications. This shim is the correct specification for DLW400ES, DLW400ESA, and DLW400ESA1 machines, making it a straightforward service replacement when precision shimming is required. Sourced directly through Multiquip's OEM supply chain, this part carries the confidence of genuine fitment verification.
Key Features
- OEM Thickness Tolerance: Manufactured to exact specification for the V1305-E2B injection pump, ensuring correct pump timing and fuel delivery alignment.
- Drop-In Service Fit: Designed to seat directly within the injection pump stack on DLW400ES series welders without additional machining or adjustment.
- Confirmed Fitment: Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welders.
- Injection Pump Integrity: A correctly shimmed injection pump maintains consistent fuel metering — a worn or missing shim can cause irregular engine performance, hard starting, or excessive smoke.
- Fuel System Compliance: Precise shim thickness is critical to maintaining correct injection timing; using a non-specification shim risks injection pump damage and emissions non-compliance.
A shim in the injection pump assembly controls the precise axial positioning of internal pump components, directly affecting fuel delivery timing and volume. On V1305-E2B diesel engines, even a small deviation in shim thickness can alter injection timing enough to cause poor combustion, increased fuel consumption, or engine damage over time. Replacing a worn or damaged shim with the correct OEM-spec component restores the pump to its designed operating parameters and protects the broader fuel system from compounding wear.
