The Multiquip 2742340203 Piston 0.25MM is a genuine OEM replacement piston designed for MT55F, MTR40F, MT54F, and MVC-40G equipment. As an authorized Multiquip OEM part, 2742340203 is manufactured to the same specifications as the original, ensuring a direct drop-in fit with no guesswork on sizing or compatibility. This 0.25MM oversized piston is a service-grade component intended for engine rebuilds where cylinder bore has been machined beyond standard dimensions. Confirm your model code and bore specification before ordering to ensure this is the correct oversize grade for your application.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to exact 0.25MM oversize tolerancing, ensuring correct piston-to-wall clearance after a matching cylinder bore regrind.
- Genuine Multiquip OEM Component — Sourced directly from Multiquip, this piston meets the same material and finish standards as the part that left the factory originally.
- Broad Rammer and Compactor Fitment — Compatible with MT55F, MTR40F, and MT54F rammers, as well as the MVC-40G plate compactor, covering multiple machines in one part number.
- Restores Full Compression — A worn or scored piston causes loss of compression, hard starting, and sluggish compaction force; replacing it with the correct oversize grade brings engine output back to spec.
- Fuel System Integrity — Proper piston sealing prevents blowby that can contaminate the crankcase with unburned fuel, protecting bearings and seals throughout the engine.
A piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force — in a rammer, that force drives the jumping action that compacts soil; in a plate compactor, it powers the exciter mechanism that generates plate vibration. When a piston wears, becomes scored, or develops ring groove damage, compression drops and the machine loses the striking energy needed to achieve proper compaction depth. The 0.25MM designation on this part indicates it is an oversized service piston, machined slightly larger than the standard bore dimension and intended for use after the cylinder has been professionally reground to match that oversize specification.
