The Multiquip 51655 Magnet RW-1403 is a genuine OEM magnet designed for the RW1403HF, RW1404, RW1404MR, and RW1404MR (S/N 326075 and up) RAMMAX walk-behind rollers. As a factory-sourced component, it carries the same specifications and tolerances as the part it replaces, ensuring correct sensor operation and signal integrity within the machine's control system. Fitment is confirmed for the RW1400-series RAMMAX roller lineup, making part selection straightforward when you have your model code on hand. DHS Equipment supplies this part direct, so you can order with confidence that you're receiving the correct OEM component.
Key Features
- OEM Magnetic Strength & Tolerancing — Sourced directly from Multiquip, this magnet meets the exact field strength and dimensional spec required for reliable sensor triggering in the RW1400-series drivetrain.
- Direct Drop-In Replacement — Engineered to the same mounting configuration as the original, allowing straightforward installation without rework or adaptation.
- Confirmed RW1400-Series Fitment — Compatible with RW1403HF, RW1404, RW1404MR, and RW1404MR units serialized at 326075 and above.
- Protects Speed & Drive Control Accuracy — A correctly functioning magnet keeps the roller's electronic control system reading drum speed accurately; a worn or weakened magnet can cause erratic drive response or control faults.
- Genuine OEM Part — Backed by Multiquip's OEM supply chain, part number 51655 is the factory-specified component — not a generic substitute.
The magnet in a RAMMAX walk-behind roller works as the trigger element in the machine's speed or position sensing system. As the drum or drivetrain rotates, the magnet passes a sensor and generates a signal pulse that the control system uses to monitor and regulate drum speed and drive output. When the magnet loses strength, shifts out of position, or fails entirely, the sensor stops receiving a clean signal — which can lead to inconsistent drive behavior, control system errors, or the machine defaulting to a fault state. Replacing a worn magnet with the correct OEM component restores accurate signal output and consistent machine operation.
