The Multiquip 71429522580 Piston with Ring OS=0.50 is a genuine OEM oversized piston assembly designed for MT-76D2 and MT-86D2 rammers as well as MVC98D2, MVH-150D2, and MVH150VD2 plate compactors. As a direct OEM replacement, this component is manufactured to the same tolerances and material specifications as the original part, ensuring a correct fit within the engine bore during a rebuild. Confirmed fitment spans both the MT and MVC/MVH equipment families, making this a versatile service part for multi-unit fleets. Order by part number 71429522580 to ensure you receive the correct oversized specification.
Key Features
- Genuine OEM Oversize Specification — Machined to the OS=0.50 oversize tolerance required during engine rebuild, maintaining proper compression and bore integrity.
- Includes Piston Ring — Supplied as a complete piston and ring assembly, so both components are matched and ready to install together without sourcing separately.
- Broad Fitment Coverage — Compatible with MT-76D2 and MT-86D2 rammers and MVC98D2, MVH-150D2, and MVH150VD2 plate compactors.
- Restores Full Compression — A worn or scored piston leads to loss of compression, poor impact force, and hard starting; replacing with a properly sized OEM piston brings engine output back to spec.
- Correct Material Grade — OEM construction means the piston alloy and ring material are matched to the engine's thermal and mechanical demands, supporting long service life after rebuild.
The piston and ring assembly sits at the heart of the engine's combustion cycle. The piston travels up and down within the cylinder bore, compressing the air-fuel mixture and transferring combustion force to the crankshaft. The piston ring seals the gap between the piston and the cylinder wall, maintaining compression and preventing oil from entering the combustion chamber. When a piston or ring wears beyond tolerance — or when a cylinder bore is re-honed to an oversize dimension — an oversized piston such as the OS=0.50 unit is required to restore the correct clearance. Installing the wrong size or a worn piston results in low compression, excessive oil consumption, and reduced machine performance.
