The Multiquip 51504 Belt Retainer Bar is a genuine OEM component designed for Essick and Whiteman plaster and mortar mixer models including EM70P/S, EM70SLF, EM90P/S, EM90SLF, WM70PLF, WM70S/P, WM70SLF, WM90PLF, WM90S/P, and WM90SLF, as well as the RW3010. As a direct OEM replacement, the 51504 is manufactured to the same specifications as the original part, ensuring a drop-in fit with no guesswork. Sourced from Multiquip's authorized parts program, this belt retainer bar is the correct choice when you need to restore your mixer or roller to proper working condition. DHS Equipment stocks this part so you can get your machine back in service without delay.
Key Features
- Genuine OEM Construction — Manufactured to the original design specification, ensuring the bar maintains proper belt tension and alignment without slipping or distorting under load.
- Direct Drop-In Replacement — Matches the original mounting points and profile on covered Essick and Whiteman mixer models, as well as the RW3010, for a straightforward swap during maintenance.
- Broad Mixer Fitment — Confirmed compatibility across EM70, EM90, WM70, and WM90 series machines, covering multiple drum and engine configurations within those families.
- Protects Drive Belt Integrity — Keeps the drive belt tracking correctly within the drive system; a worn or missing retainer bar allows belt wander that leads to accelerated belt wear and loss of drum rotation efficiency.
- Drive System Safety — A properly seated belt retainer bar prevents unexpected belt disengagement during operation, reducing the risk of abrupt drum stoppage or belt ejection.
The belt retainer bar holds the drive belt in its correct lateral position within the mixer or roller drive system, preventing the belt from walking off the pulleys during operation. Without this component seated correctly, the belt is free to shift under load, causing uneven wear, slipping, and eventual belt failure that brings the machine to a stop. Replacing a damaged or missing retainer bar is a straightforward service step that restores full drive efficiency and protects the surrounding pulley and belt components from secondary damage.
