Multiquip 18266M Hose Pump WPB-16 - OEM Replacement Part

This hydraulic pump hose connects the hydraulic pump to the directional control valve and dump system on Multiquip power buggies, enabling hydraulic fluid flow for dump cylinder operation and drive motor functions. The hose is a critical component in both Hydro-Gear and Eaton hydraulic system configurations, routing pressurized hydraulic oil from the pump through the system's in-line filters (100-149 mesh depending on model) to the dump valve and drive motors. Regular inspection of this hose is essential during routine hydraulic system maintenance to prevent leaks, contamination of the hydraulic oil tank, and loss of dump control or drive function.

On WBH-16EAWD models, this hose interfaces with the Hydro-Gear hydraulic pump and directional control valve, supporting up to 17 GPM flow in Eaton-equipped systems. Failed or deteriorated pump hoses can result in reduced hydraulic pressure, sluggish dump cylinder response at the 88° dump angle, or complete loss of hydraulic drive motor power. Replacement should be performed whenever hoses show signs of cracking, bulging, or seepage at connection points.

Compatible with the following Multiquip power buggy models:

• WBH-16
• WBH-16EAWD
• WBH-21EF
• WBH-21EFP
