The Multiquip EM50308 Hayes Coupling Mounting Plate St60,80 is a genuine OEM component designed for RAMMAX walk-behind roller models including the RW1404MR, RW1404, and RW1504HF (up to S/N ). As a factory-original part, EM50308 is manufactured to the exact specifications required for correct coupling alignment and secure mounting on these compaction rollers. Verify your model code and serial number against the fitment data to ensure compatibility before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the plate geometry, hole pattern, and material grade match what came off the assembly line.
- Direct Bolt-On Replacement — Mounts in the factory position with no rework needed, maintaining proper Hayes coupling alignment and drivetrain concentricity.
- Confirmed Fitment — Compatible with RW1404MR (S/N 326075 and up), RW1404, and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Coupling Integrity — A correctly seated mounting plate keeps the Hayes coupling stable under load, preventing vibration-induced wear on adjacent drivetrain components.
- Serial-Number Specific — Fitment is verified against documented serial number breaks, so you can order with confidence that EM50308 is the right plate for your specific machine build.
The Hayes coupling mounting plate serves as the structural interface between the Hayes coupling assembly and the roller drivetrain housing. It holds the coupling in precise alignment so that torque is transferred smoothly from the drive source to the drum without lateral stress or deflection. When this plate becomes cracked, warped, or worn at the mounting surfaces, coupling misalignment follows — leading to accelerated wear on the coupling itself, increased vibration, and potential drivetrain damage that sidelines the machine entirely.
