Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grade as the original piston assembly, ensuring proper compression characteristics and cylinder wall clearance specific to Multiquip engines.
- Oversized Specification — Purpose-built for engines with a bored or honed cylinder, providing the correct oversized diameter for a proper seal against a reconditioned cylinder wall.
- Broad Multiquip Fitment — Compatible with MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D models, covering reversible plate compactor, trash pump, and power trowel applications within the Multiquip lineup.
- Restores Engine Compression — A correctly sized piston assembly maintains the compression ratio needed for reliable starting and full power output; a worn or undersized piston leads to blow-by, hard starting, and loss of performance.
- Drop-In Engine Rebuild Component — Supplied as a complete piston assembly, simplifying the rebuild process by consolidating the core piston components into a single verified part.
The piston assembly is a core reciprocating component inside the engine cylinder. It transfers the force generated by combustion down through the connecting rod to drive the crankshaft, which ultimately powers the machine's working components. An oversized piston assembly is used specifically when an engine cylinder has been bored out to remove wear or scoring — installing the correct oversized specification restores proper compression and sealing. When a piston is worn, cracked, or incorrectly sized, the engine loses compression, consumes oil, and delivers reduced power output, making prompt replacement critical to keeping the host machine operating at full capacity.
