Multiquip 802922 Oil Drain Hose - OEM Replacement Part

This oil drain hose ensures proper hydraulic oil return flow in Multiquip concrete buggies, connecting critical components in the hydraulic system to allow filtered oil to return from the drum drive motors back to the hydrostatic pump. In equipment like the AR14H vibratory roller, hydraulic oil circulation is essential for powering the dual drum drive motors and maintaining proper system pressure during forward and reverse operations.

The hose must maintain integrity under continuous pressure cycling as the travel lever switches between forward (port A high-pressure) and reverse (port B high-pressure) modes. Failed or deteriorating drain hoses can cause hydraulic oil leaks, leading to contamination, reduced system pressure, and potential damage to the hydrostatic pump or gear pump assemblies. Regular inspection of hydraulic hoses should be performed during routine maintenance intervals to check for cracks, bulging, or oil seepage at connection points.

This drain hose is designed for use in demanding construction environments where the hydraulic system powers drum vibration, articulating steering, and travel functions. Compatible models include:

• AR14H Vibratory Ride-On Roller
• WTB-16 Concrete Buggy
• WTB-16PD Concrete Buggy
