The Multiquip 514235 Key Style Coupler is a genuine OEM component designed for Essick and Whiteman concrete and mortar mixer series. This direct-replacement coupler is verified to fit EM120P Series, EM120S Series, EM120, WM120PH, and WM120SH mixer models, making it a trusted choice for operators maintaining equipment in these lines. As a factory-sourced part, it meets the original design specifications that Multiquip engineers built into these machines. When you need a dependable coupler to restore full mixing function, the 514235 delivers the correct fit and construction.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances for the keyed drive interface, ensuring the coupler transmits torque without slippage or premature wear.
- Key Style Drive Engagement — The keyed profile locks positively onto the shaft, providing a secure mechanical connection that resists rotational play under the sustained load of mixer operation.
- Confirmed Mixer Compatibility — Fits EM120P Series, EM120S Series, EM120, WM120PH, and WM120SH — covering both Essick and Whiteman 120-class mixer platforms.
- Restores Full Drive Transmission — A worn or damaged coupler causes power loss between the engine and drum, resulting in sluggish or stopped mixing; replacing it with the correct OEM part brings drive performance back to spec.
- Exact Part Number Reference — Part number 514235 is the Multiquip OEM reference for this application — cross-check this number against your machine's parts manual to confirm the correct selection before ordering.
A key style coupler serves as the mechanical link between the drive shaft and the driven component in the mixer's power transmission system. The keyed connection prevents the mating parts from rotating independently of one another, transferring engine torque directly into drum movement. When a coupler cracks, chips, or the keyway wears out of tolerance, the drive connection becomes unreliable — the drum may slip, turn inconsistently, or stop rotating altogether — making prompt replacement essential to keeping the mixer productive on the job.
