Multiquip 800771 Coupling Engine/Pump - OEM Replacement Part

This engine/pump coupling provides the critical mechanical connection between the engine and hydrostatic pump on Multiquip walk-behind rollers, transferring power to drive the hydraulic system that controls roller movement and operation. The coupling ensures proper alignment and torque transfer from the engine to the hydrostatic pump, which provides hydraulic pressure to the entire drive system including forward and reverse travel functions.

When this coupling fails or wears, operators may experience loss of hydraulic pressure, inability to move the roller forward or reverse, or unusual vibration and noise from the pump area. The coupling works in conjunction with the cogged drive belt system to maintain consistent power delivery to the hydrostatic pump. Regular inspection of this coupling during scheduled maintenance helps prevent unexpected downtime and ensures the hydrostatic fluid reservoir maintains proper pressure for smooth travel lever operation.

Compatible with the following Multiquip roller models:

• V305EH
• V305EK
