The Multiquip 13156 Pin Style Coupler is a genuine OEM replacement designed for Essick and Whiteman plaster and mortar mixer models, including the EM120P Series, EM120S Series, WM120PH, and WM120SH. As an authentic Multiquip OEM component, this coupler is manufactured to the same standards as the original part installed at the factory, ensuring a direct, trouble-free installation with no improvisation needed. Sourced directly through authorized Multiquip distribution channels, the 13156 is the correct part for keeping these mixers operating at full efficiency. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the pin engagement and coupler geometry match the drivetrain components exactly as designed.
- Direct-Swap Installation — Replaces the existing coupler using the original mounting points and pin configuration, allowing straightforward removal and reinstallation in the field.
- Broad Mixer Compatibility — Confirmed fitment for EM120P Series, EM120S Series, WM120PH, and WM120SH Essick and Whiteman plaster and mortar mixers.
- Torque Transmission Integrity — A correctly functioning coupler transfers power cleanly between the motor and drum; a worn or failed coupler causes slippage, erratic drum rotation, or complete loss of drive.
- Correct Part for Mixed Drum Types — Fits both steel drum (S) and plastic/polyurethane drum (P) variants within the 120-series Essick and Whiteman mixer lines.
A pin style coupler serves as the mechanical link between the mixer's drive system and the drum, transmitting rotational force from the motor output shaft to keep the drum turning consistently under load. The pin engagement design allows the coupler to absorb minor misalignment and shock loads during operation, which is especially important in demanding plaster and mortar mixing applications where material resistance varies. When the coupler wears or the pin shears, the drum loses drive entirely or rotates inconsistently, resulting in poorly mixed material and extended batch times.
