Multiquip 1624121310 Piston Pin V1205B BLW-400SSW

The Multiquip 1624121310 is a genuine OEM Piston Pin V1205B BLW-400SSW designed for the DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder series. As a factory-sourced component, this piston pin is manufactured to the exact tolerances required by the V1205B engine assembly, ensuring proper alignment and fit within the engine block. DHS Equipment supplies this part directly as an authorized Multiquip OEM replacement, so you can order with confidence knowing you're getting the correct component for your machine. Verify your model code against the DLW400ES series before ordering to confirm fitment.

Key Features

• Genuine OEM Tolerancing: — Manufactured to the precise dimensional specs of the V1205B engine, ensuring the pin seats correctly within the piston and connecting rod bore without adjustment.
• Direct Engine Assembly Fit: — Engineered as a drop-in replacement for the DLW400ES, DLW400ESA, and DLW400ESA1 welder engine, matching the original component's diameter and surface finish.
• DLW400ES Series Compatibility: — Confirmed fitment across the DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welder models.
• Engine Integrity Protection: — A correctly fitted piston pin maintains proper combustion stroke geometry; a worn or undersized pin causes piston slap, accelerated cylinder wall wear, and potential engine failure.
• Authorized OEM Supply: — Sourced and sold through DHS Equipment as a genuine Multiquip part, backed by the manufacturer's OEM parts program.

The piston pin — also called a wrist pin — connects the piston to the small end of the connecting rod, transferring combustion force into rotational motion at the crankshaft. It must maintain an exact fit within both the piston bore and the rod bushing to keep the piston stable through each power stroke. When a piston pin wears, becomes loose, or develops surface damage, it produces audible knocking, increases blowby past the piston rings, and can cause catastrophic internal engine damage if left unaddressed.
