Multiquip 21770 Key for Eaton Motor - OEM Replacement Part

This key provides the critical mechanical connection between the Eaton motor shaft and the drive component on Multiquip ride-on trowels, transmitting rotational torque while preventing slippage during high-load finishing operations. Designed specifically for the HTX-44K4 ride-on trowel's electrical system, this key ensures proper power transfer from the motor to the trowel's drive mechanism.

As part of the wiring and motor assembly referenced in the HTX-44K/Y ride-on trowel wiring diagram, this component is essential for maintaining reliable motor performance. Motor keys can wear, shear, or become damaged due to overload conditions, startup stress, or improper installation. Signs of a failing motor key include unusual vibration, intermittent power transfer, or the motor shaft rotating without engaging the drive system. Regular inspection during motor maintenance helps prevent unexpected downtime on the job site.
