The Multiquip 1547135012 Oil Pump Assembly is a genuine OEM component designed for the DAW-500S diesel arc welder/generator. Sourced directly from Multiquip, this assembly matches the original specification installed at the factory, ensuring a correct, direct-fit replacement with no guesswork. Whether you're completing a scheduled overhaul or addressing an unexpected lubrication failure, the part restores proper oil circulation to get your DAW-500S back on the job fast.
Key Features
- Genuine OEM Lubrication Integrity — Manufactured to the exact tolerancing and flow-rate specification of the original oil pump, ensuring consistent pressure delivery throughout the engine's lubrication circuit.
- Direct-Fit Replacement — Engineered to mount in the original pump position on the DAW-500S, matching all port sizing and bolt patterns for a straightforward installation.
- Confirmed DAW-500S Compatibility — Verified fitment for the Multiquip DAW-500S diesel arc welder/generator series, so you can order with confidence.
- Sustained Engine Protection — A correctly functioning oil pump maintains the oil pressure needed to lubricate bearings, journals, and moving engine components — preventing premature wear and engine damage caused by oil starvation.
- Critical Fuel-System Adjacent Safety — Proper oil pressure is essential to safe, continuous operation of diesel-powered equipment; replacing a failing pump promptly prevents cascading engine damage and unplanned equipment shutdown on the worksite.
The oil pump assembly is responsible for drawing engine oil from the sump and circulating it under pressure to all critical lubrication points throughout the engine. Without adequate oil pressure, bearings, camshafts, and other moving components wear rapidly and can seize. On a diesel arc welder like the DAW-500S — where the engine runs continuously under load — a failing or worn oil pump will cause a drop in oil pressure, trigger low-pressure warning systems, and ultimately risk serious internal engine damage if not addressed promptly.
