The Multiquip 1735174250 Fan Pulley is a genuine OEM component designed for the DAW-500S diesel arc welder. As a direct OEM replacement, this pulley is produced to the same specification as the original part, ensuring proper belt alignment and consistent cooling fan operation. If you're servicing a DAW-500S welder, verifying the part number against your machine's parts manual is always recommended before ordering.
Key Features
- OEM-Grade Pulley Geometry — Machined to the same diameter and groove profile as the original, ensuring correct belt tracking and tension on the DAW-500S cooling system.
- Direct-Mount Replacement — Mounts to the original shaft position with no modification to brackets or hardware, keeping your service time short.
- Confirmed DAW-500S Fitment — Sourced specifically for the Multiquip DAW-500S diesel arc welder; cross-reference part number 1735174250 with your machine's parts list before installation.
- Supports Stable Engine Cooling — A correctly sized and balanced pulley maintains the fan speed needed to keep the engine running at safe operating temperatures under sustained welding loads.
- Genuine Multiquip OEM Part — Supplied as original equipment, not a generic substitute, so you can be confident in material grade and dimensional accuracy for a long service life.
The fan pulley transfers rotational power from the engine's drive belt to the cooling fan, maintaining consistent airflow across the engine and electrical components during operation. A worn, cracked, or out-of-round pulley causes belt slippage, uneven fan speed, and ultimately overheating — which on a diesel arc welder under continuous load can lead to thermal shutdowns or accelerated engine wear. Replacing a damaged pulley with a correctly specified OEM part restores proper belt engagement and keeps the cooling system performing as intended.
