The Multiquip 01247300 Piston Ring Set 100 is a genuine OEM component designed for MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D series equipment. As a direct OEM replacement, this piston ring set is manufactured to the exact tolerances required to maintain proper compression and oil control in your engine. Confirm your model and engine specification before ordering to ensure a correct fit across these equipment families.
Key Features
- OEM-Grade Compression Sealing — Manufactured to exact bore tolerances for consistent ring-to-wall contact, maintaining proper cylinder compression across the supported engine.
- Direct OEM Replacement — the part installs into the piston grooves without machining or modification, restoring the engine to its original operating specification.
- Broad Equipment Compatibility — Fits MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D models, covering heavy-duty plate compactor, trash pump, and power trowel applications in the Multiquip lineup.
- Restores Engine Oil Control — Worn or broken piston rings allow oil to bypass into the combustion chamber, causing smoke, power loss, and accelerated engine wear. A fresh set restores the oil film barrier and keeps combustion gases where they belong.
- Fuel Efficiency and Power Output — Properly seated rings maintain cylinder pressure, which directly supports consistent horsepower output and helps prevent excessive fuel consumption during operation.
Piston rings are precision-fit components that sit in grooves around the piston inside the engine cylinder. Their job is to seal combustion gases above the piston, prevent engine oil from entering the combustion chamber, and transfer heat away from the piston into the cylinder wall. When rings wear, crack, or lose tension, the engine loses compression — resulting in hard starting, reduced power, increased oil consumption, and visible exhaust smoke. Replacing the piston ring set with a genuine Multiquip 01247300 restores the mechanical seal that keeps the engine running at full capacity.
