The Multiquip 551438340 Gear Hub Motor MRX-440P is a genuine OEM component designed for the MRX-440P walk-behind roller. Sourced directly from Multiquip, this part meets the exact build specifications of the original unit, ensuring it integrates seamlessly into the drive system of your MRX-440P. Confirmed fitment for the MRX-440P series makes this the straightforward, no-guesswork choice when your machine needs a motor replacement.
Key Features
- Genuine OEM Construction — Built to the same torque and load specifications as the original gear hub motor, maintaining the drive performance your MRX-440P was designed to deliver.
- Direct-Fit for MRX-440P — Matches the original mounting configuration and drive interface of the MRX-440P walk-behind roller for a straightforward swap.
- MRX-440P Confirmed Fitment — Verified for the MRX-440P RAMMAX walk-behind roller; check your model plate before ordering to confirm compatibility.
- Drive System Integrity — A functioning gear hub motor is essential for consistent drum propulsion; a worn or failed unit can cause loss of drive, uneven compaction passes, and added operator strain.
- OEM Part Number 551438340 — Cross-reference this number against your Multiquip parts manual to confirm this is the correct motor for your application before installation.
The gear hub motor on a walk-behind roller is responsible for converting hydraulic or mechanical power into rotational force that drives the drum forward and in reverse. It is a core propulsion component — without it functioning correctly, the roller cannot maintain steady travel speed or consistent drum contact with the surface being compacted. When the gear hub motor wears or fails, operators typically notice sluggish drive response, loss of propulsion in one direction, or complete inability to self-propel, all of which directly compromise compaction quality and machine control.
