Multiquip 1194416 Hydraulic Pump - OEM Replacement Part

This hydraulic pump powers the travel and steering systems on Multiquip RX1575 trench rollers, delivering pressurized fluid to the servo block, steering pistons, and travel motors. The pump integrates with the valve block assembly to control directional movement, steering response, and hydrostatic drive functions.

According to Multiquip service documentation, this pump works in conjunction with magnetic valves Y3 and Y4 to regulate travel control. During troubleshooting procedures, technicians should verify that oil flows back to the pump housing when plugs X1 and X2 are removed—if oil does not flow, apertures may be clogged or the piston jammed out of center. The pump connects to the valve block which must be lifted from the chassis for access during service. Common symptoms requiring pump inspection include machine moving in only one direction, slow travel speed even with lever at limit position, or unequal movement response.

The hydraulic system includes connections for steering pistons (B3 designation), travel motors (T3), and return flow through the oil cooler and filter (T1). Regular inspection of magnetic valve seals and proper lubrication during maintenance helps ensure reliable pump operation.
