Multiquip 1217513 Fluid Motor - OEM Replacement Part for Trench Rollers

This fluid motor is a critical component of the travel system on Multiquip trench rollers, converting hydraulic pressure into mechanical rotation to drive the machine's movement. This part has been superseded by part number 1316837, which is the current replacement unit specified by Multiquip engineering.

The fluid motor integrates with the vibration control pump assembly and travel hydraulics system, working in conjunction with the 11 ccm/rev gear pump to provide reliable hydrostatic drive performance. Proper installation requires applying NeverSeez compound to the shaft during assembly. The travel system operates with hydrostatic braking, with steering pressure maintained at 67 ± 8 bar and standard system pressure at 220 ± 10 bar. During maintenance or replacement, technicians should verify travel pump zero position adjustment and inspect the servo block magnetic coil per service manual chapter 18.2.7.

This hydraulic motor is engineered to handle the demanding conditions of trench compaction operations, ensuring consistent travel performance and torque delivery throughout the machine's duty cycle.
