Multiquip 1627124980 Idle Gear Bush V1205B

The Multiquip 1627124980 Idle Gear Bush V1205B is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a factory-sourced part, 1627124980 is manufactured to the exact tolerances required for correct gear mesh and bearing clearance within the engine's gear train. Sourcing the correct OEM bush ensures the idle gear operates within its designed parameters, protecting both the gear and the surrounding components from accelerated wear. DHS Equipment stocks this part to keep your DLW400ES welder running at full capacity.

Key Features

• OEM-Grade Bore Tolerancing — Manufactured to the precise inner diameter specification for the V1205B engine's idle gear, ensuring correct shaft clearance and smooth rotation under load.
• Drop-In Fitment for DLW400ES Series — Engineered to seat directly into the idle gear assembly on DLW400ES, DLW400ESA, and DLW400ESA1 welders with no machining or shimming required.
• Genuine Multiquip OEM Part — Sourced directly through Multiquip's authorized supply chain, carrying part number 1627124980 for verified fitment accuracy.
• Protects Gear Train Integrity — A worn or oversized bush allows the idle gear to shift off-axis, accelerating tooth wear and increasing engine noise — replacing it on schedule preserves drivetrain alignment.
• Correct Material Grade — Produced from the specified bearing material to handle the continuous rotational load and heat cycles typical of diesel welder engine operation.

The idle gear bush is a small but critical bearing surface that supports the idle gear within the engine's gear train, allowing it to rotate freely while maintaining precise center-to-center spacing between meshing gears. In a diesel engine like the V1205B used in the DLW400ES series, the gear train drives the camshaft and auxiliary components, so any play introduced by a worn bush translates directly into timing inconsistency, increased gear noise, and accelerated wear on adjacent components. Replacing a worn idle gear bush with a correctly specified OEM part restores proper gear mesh geometry and helps prevent more costly drivetrain repairs.
