The Multiquip 1642774282 Fan Drive Pulley is a genuine OEM component designed for the DAW-500S diesel arc welder.

If you're servicing a DAW-500S and need a dependable, like-for-like replacement, this is the part to order.
Key Features
- Genuine OEM Construction — Machined to the precise dimensions and tolerances of the original pulley, maintaining correct belt alignment and drive geometry on the DAW-500S.
- Direct-Fit Replacement — Mounts to the existing drive assembly without alteration, matching the original bolt pattern, bore, and profile exactly.
- DAW-500S Welder Fitment — Confirmed fitment for the Multiquip DAW-500S diesel arc welder, so you can order with confidence.
- Cooling System Integrity — A correctly functioning fan drive pulley keeps the cooling fan spinning at the right speed, protecting the engine and electrical components from heat stress during sustained welding operations.
- Prevents Belt Wear and Slippage — A worn or damaged pulley causes belt misalignment, accelerated belt wear, and inconsistent fan speed — replacing it with an OEM unit restores proper drive performance.
The fan drive pulley transfers rotational power from the engine to the cooling fan via a drive belt. It keeps the fan operating at the correct speed to maintain safe operating temperatures inside the welder enclosure. When the pulley wears, cracks, or becomes misaligned, it can cause belt slipping, uneven fan operation, or complete loss of cooling airflow — leading to overheating and potential damage to the engine or welding components. Replacing it promptly with a genuine OEM part restores full cooling performance and protects the machine during heavy-duty use.
