Multiquip 11378 Coupling Pump .75ID x 13T SPL-50TOD - OEM Replacement Part

This pump coupling connects the engine's power transmission system to the hydraulic pump on ride-on power trowels, enabling the hydraulic system that controls blade pitch and steering. The coupling features a 0.75-inch inner diameter bore with 13 teeth and SPL-50 ton outer diameter specifications, ensuring precise fitment and torque transfer in demanding concrete finishing applications.

Designed specifically for Multiquip's HTX-44K series ride-on trowels, this coupling is a critical component in the hydraulic drive system. Worn or damaged couplings can cause excessive vibration, loss of hydraulic pressure, difficulty steering, or complete hydraulic system failure. Regular inspection of the coupling for wear, cracks, or missing teeth should be part of your preventive maintenance routine, especially on high-hour machines or those operating in dusty concrete finishing environments.
