Multiquip 807443 Chain Coupler - OEM Replacement Part for Stationary Mixers

The chain coupler is a critical drivetrain component that transfers rotational power from the hydraulic motor to the mixing drum assembly in stationary mortar and plaster mixers. This coupler works in conjunction with the bidirectional hydraulic motor system to enable both mixing and dump positioning operations, ensuring reliable power transmission during continuous mixing cycles.

In the PRO20 stationary mixer system, the chain coupler connects the hydraulic drive system to the drum mechanism, allowing operators to control drum rotation for mixing plaster and mortar compounds. This component must withstand constant torque loads and directional changes as the mixer operates in both forward and reverse modes. Worn or damaged chain couplers can result in slipping, inconsistent mixing action, or complete loss of drum rotation. Regular inspection of the chain coupler during daily maintenance procedures—performed alongside drum bearing greasing with lithium-based EP grease—helps identify wear before failure occurs.
