The Multiquip 2842351107 Piston Ring Set is a genuine OEM component designed for MT55F, MTR40F, and MTR40SF rammers. This set delivers the exact ring dimensions and material tolerances required by the engine to maintain proper cylinder sealing and combustion efficiency. Sourced directly from Multiquip, it is a direct match for the original rings fitted at the factory, ensuring a proper installation without guesswork. If you are servicing a rammer in the MT or MTR series, part number 2842351107 is the correct OEM choice for a lasting engine rebuild.
Key Features
- OEM-Grade Ring Tolerancing — Manufactured to the exact radial thickness and gap specifications required for proper cylinder wall sealing in these rammer engines.
- Drop-In Engine Rebuild Fit — Matches the original ring groove dimensions on the piston, allowing straightforward installation during a top-end engine service.
- Confirmed Fitment for MT and MTR Series Rammers — Verified compatible with MT55F, MTR40F, and MTR40SF models.
- Restores Compression and Power — Worn or broken piston rings cause loss of compression, increased oil consumption, and hard starting; a fresh set brings combustion performance back to spec.
- Fuel System and Combustion Integrity — Correct ring sealing prevents blow-by gases from contaminating the crankcase, protecting downstream engine components from accelerated wear.
Piston rings form the dynamic seal between the piston and the cylinder wall, allowing the engine to build and hold compression during each power stroke. In a rammer, where the engine is subjected to constant reciprocating stress and vibration, ring wear is one of the most common causes of reduced impact force, increased fuel consumption, and hard starting. When rings lose their sealing tension or break, combustion gases escape past the piston — a condition known as blow-by — which contaminates the oil and accelerates wear throughout the engine. Replacing the piston rings as part of a top-end engine rebuild restores compression, improves throttle response, and extends the overall service life of the machine.
