The Multiquip 1733121090 Piston Ring Assembly is a genuine OEM component designed for the DAW-500S diesel arc welder. Sourced directly from Multiquip, this assembly matches the original engineering specifications of the engine, ensuring proper sealing and compression are restored on installation. If you're servicing a DAW-500S and need a dependable, exact-match piston ring set, this is the correct OEM part for the job.
Key Features
- OEM Engine Tolerances Met — Manufactured to the same compression and gap specifications as the original rings, maintaining proper cylinder sealing in the DAW-500S engine.
- Direct-Fit Assembly — Designed to drop into the existing cylinder bore without reworking or shimming, streamlining the rebuild process.
- DAW-500S Compatibility — Confirmed fitment for the Multiquip DAW-500S diesel arc welder, so you're ordering the right assembly the first time.
- Compression Restoration — Worn or broken piston rings rob the engine of power and increase oil consumption; this assembly brings cylinder sealing back to operational spec.
- Fuel Efficiency Maintained — Proper ring seal keeps combustion gases where they belong, preventing blow-by that wastes fuel and contaminates engine oil.
Piston rings form a dynamic seal between the piston and the cylinder wall, controlling combustion pressure and regulating oil film on the cylinder bore. When rings wear, crack, or lose tension, combustion gases escape past the piston — a condition known as blow-by — which reduces engine power output, increases fuel consumption, and allows oil to enter the combustion chamber. Replacing the piston ring assembly restores cylinder compression, brings oil consumption back to normal, and allows the engine to deliver the consistent output that a demanding application like arc welding requires.
