The Multiquip 551441270 is a genuine OEM Cylinder DNO designed for the MRX-440P walk-behind roller. Sourced directly through the Multiquip parts network, this cylinder is built to the exact specifications required by the MRX-440P, ensuring a correct, direct installation with no guesswork. If your roller is showing signs of compression loss, excessive oil consumption, or reduced compaction power, this is the component to restore it to full working condition. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing you're getting the right part for your machine.
Key Features
- OEM-Grade Cylinder Construction — Manufactured to Multiquip's original tolerances, delivering the bore geometry and surface finish critical to proper compression and piston seal performance.
- Direct-Fit for MRX-440P — Engineered specifically for the MRX-440P walk-behind roller, aligning with all existing mounting points and engine assembly interfaces for a straightforward installation.
- Restores Full Compression — A fresh cylinder brings engine compression back to spec, allowing the MRX-440P to deliver consistent drum vibration and compaction output across the full working range.
- Genuine Multiquip OEM Part — Part number 551441270 is an authentic Multiquip component, not a generic substitute, meaning material grade and dimensional accuracy match the original production part.
- Prevents Secondary Engine Damage — Replacing a worn or scored cylinder promptly protects pistons, rings, and bearings from accelerated wear caused by blow-by and lost compression.
The cylinder is the core structural and functional component of a reciprocating engine's power generation. It forms the sealed combustion chamber where air and fuel mix, ignite, and expand to drive the piston — converting combustion energy into the mechanical force that powers the drum and vibration system of the MRX-440P roller. When a cylinder becomes worn, scored, or cracked, compression drops, the engine loses power, oil consumption increases, and the machine can no longer compact effectively. Replacing the cylinder with a correctly specified OEM part restores the engine's ability to build and hold the compression needed for consistent, reliable operation.
