The Multiquip 551327560 Motor Flange MRX-440 is a genuine OEM Motor Flange MRX-440 designed for the MRX-440 walk-behind roller. As a factory-sourced component, this part is manufactured to the exact tolerances and material specifications required by the MRX-440, ensuring a correct, secure connection between the motor and the surrounding drive assembly. Sourced directly through Multiquip's OEM supply chain, the part is the same part that ships with new equipment — giving you confidence in fitment and function from the first installation.
Key Features
- Genuine OEM Integrity — Manufactured to the exact material and dimensional specifications of the original flange, not an approximation — critical for maintaining proper motor alignment and load transfer on the MRX-440.
- Direct-Mount Replacement — Engineered to bolt directly into the existing motor interface on the MRX-440 with no reworking of mounting surfaces or hardware.
- Confirmed MRX-440 Fitment — Verified OEM compatibility with the MRX-440 walk-behind roller; part number 551327560 is specific to this machine.
- Structural Load Integrity — A correctly fitted motor flange maintains concentricity between the motor shaft and driven components — a worn or cracked flange can cause vibration, misalignment, and accelerated bearing wear throughout the drivetrain.
- Drive System Reliability — Keeping this flange in serviceable condition is essential to consistent drum drive performance and smooth roller operation on compaction passes.
The motor flange is a precision structural interface component that connects the drive motor to the roller's drivetrain. It locates the motor in the correct rotational and axial position, ensuring that torque is transferred smoothly and evenly from the motor shaft to the driven assembly without vibration or binding. When a motor flange becomes cracked, corroded, or dimensionally distorted, the resulting misalignment puts stress on the motor bearings, output shaft, and adjacent drive components — leading to vibration, noise, and eventual drivetrain failure if left unaddressed.
