The Multiquip 71431022580 is a genuine OEM Piston with Rings (OS 0.5) designed for MVH406DSY and MRH800DS2 series equipment. As a direct Multiquip OEM component, this oversize piston is built to exact dimensional and material specifications to restore proper engine performance after a bore is honed or resized. Confirm your model code and bore specification before ordering to ensure correct fitment with your MVH406DSY or MRH800DS2 unit.
Key Features
- Oversize Engine Rebuild Spec: — Sized at OS 0.5 for use in engines that have been bored out, ensuring correct wall clearance and compression seal after a machine overhaul.
- Genuine OEM Construction: — Manufactured to Multiquip's original piston diameter, ring groove depth, and alloy grade — no guesswork on material compatibility or dimensional tolerance.
- Complete Piston and Ring Assembly: — Supplied with rings included, so you have everything needed to complete the piston installation in a single part order.
- Confirmed Fitment: — Engineered specifically for the MVH406DSY reversible plate compactor and MRH800DS2 walk-behind roller, both diesel-powered Multiquip machines.
- Compression Integrity: — A correctly fitted piston and ring set maintains proper compression ratio, directly affecting engine power output, fuel efficiency, and smooth operation under load.
The piston and ring set form the core of the engine's power stroke — the piston travels within the cylinder bore to compress the air-fuel mixture, while the rings seal combustion gases above and control oil below. When a piston is worn, scored, or the bore has been resized, installing the correct oversize piston (in this case OS 0.5) restores that seal and recovers lost compression. Running a worn or improperly sized piston leads to oil consumption, loss of power, hard starting, and eventual engine failure, making this a critical component in any engine rebuild or top-end overhaul.
