The Multiquip 71421022620 Piston with Rings OS=0.25 is a genuine OEM component designed for MVH-200DA2, MVH206D, and MVH-306DS2 reversible plate compactors. As a factory-sourced part, 71421022620 meets the exact dimensional and material standards Multiquip built into these machines. This oversized piston and ring set is a precision engine rebuild component, ensuring proper cylinder wall fit when standard sizing is no longer viable after wear. Confirm your model and bore measurement before ordering to ensure correct fitment across the MVH series.
Key Features
- Oversized Engine Rebuild Spec: — Sized at OS=0.25 oversize to restore proper piston-to-cylinder clearance after a bore has been measured and machined beyond standard tolerances.
- Complete Piston and Ring Set: — Supplied as an assembly with rings included, reducing the risk of mismatched components and simplifying the engine rebuild process.
- Genuine OEM Construction: — Manufactured to Multiquip's original material and dimensional specifications, maintaining the compression ratios and thermal tolerances the engine was engineered around.
- MVH Series Compatibility: — Verified fitment for MVH-200DA2, MVH206D, and MVH-306DS2 reversible plate compactors — heavy-duty units where engine longevity directly impacts compaction output.
- Compression Restoration: — A worn or out-of-spec piston causes loss of compression, hard starting, excessive oil consumption, and reduced centrifugal force output; this assembly restores proper cylinder function.
The piston and ring assembly is the core reciprocating component inside the engine's cylinder. The piston transfers combustion pressure into crankshaft rotation, while the rings seal combustion gases above the piston and control oil below it. When rings wear or the piston skirt loses its fit against the cylinder wall, compression drops, oil burns into the combustion chamber, and the engine loses the power needed to drive the compaction mechanism effectively. An oversized piston like the part is used specifically after a cylinder has been rebored to remove scoring or out-of-round wear — it fills the enlarged bore to the correct clearance and brings compression back to operating specification.
