Buyers Products hydra star series hydraulic motors are economical, efficient, small, compact, & powerful. Designed for medium-duty applications, these motors have the industry Proven Spool value combined with state-of-the-art gerotors.

• REPLACEMENT SPINNER MOTOR: Purpose-built for SaltDogg spreaders; 4-bolt mount, 1 in round shaft with 0.25 in keyway, 1/2 in NPT ports, 3.1 cu in displacement. Delivers reliable power in a compact package to match OEM performance in winter service.
• ECONOMICAL, EFFICIENT POWER: Proven spool valve and advanced gerotors cut internal leakage, improve volumetric efficiency, and sustain output under load. Built to balance durability and cost for fleet maintenance and municipal spreader duty.
• HIGH START-UP TORQUE: Strong breakaway torque for heavy loads at launch, with the right blend of torque and flow to keep spinner speed steady across variable materials and temperatures common to salt and aggregate applications.
• MEDIUM-DUTY VERSATILITY: Ideal hydraulic drive for compressors, augers, winches, cranes, and spreaders; compact footprint and simple plumbing with 1/2 in NPT ports make integration straightforward across truck and trailer hydraulic systems.
• EASY INSTALL & SERVICE: 4-bolt BA flange mount and blunt, 1 in shaft with 0.25 in keyway support quick swaps; component-grade construction helps reduce downtime, and standardized CM-series form factors simplify sourcing across fleets and upfitters.
