The Multiquip 1642724250 Idle Gear Shaft is a genuine OEM component designed for the DAW-500S diesel arc welder. Sourced directly from Multiquip, this part meets the original engineering specifications for the DAW-500S and installs as a direct replacement with no guesswork involved. Keeping the correct idle gear shaft in service is essential to maintaining proper drivetrain function and consistent output performance on the welder.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional tolerances specified for the DAW-500S idle gear drivetrain, ensuring correct mesh and load transfer.
- Direct OEM Replacement — Engineered to drop into the existing gear assembly on DAW-500S welders, aligning precisely with mating gear components for proper engagement.
- DAW-500S Fitment Confirmed — Verified replacement for the Multiquip DAW-500S diesel arc welder series, so you can order with confidence.
- Sustained Power Transfer — A correctly functioning idle gear shaft maintains consistent rotational force through the gear train, supporting stable welding output and engine load management.
- Wear Resistance — OEM shaft material is selected for hardness and durability under the continuous rotational load demands of a diesel-driven welder generator.
The idle gear shaft is a core component within the gear train of the DAW-500S welder, transmitting rotational force between the engine and the generator assembly by acting as an intermediary gear carrier. It keeps the gear mesh properly spaced and aligned so that power flows smoothly and consistently from the engine through to the alternator side of the machine. When the idle gear shaft wears, cracks, or fails, it can cause gear noise, erratic power output, or complete loss of drive — making timely replacement critical to keeping the welder operational on the job.
