About White Drive Products
Hydraulic Motors & Propulsion Systems Solutions
White Drive Products is a premier supplier of hydraulic components designed specifically for mobile propulsion systems, including compact agricultural equipment, construction machinery, forestry vehicles, and industrial material-handling equipment. The company specializes in Geroter orbital motor designs (spool, commutator, and disc valve configurations) that deliver reliable torque and speed control across variable-load scenarios where smooth power delivery and durability are essential.
The White Drive portfolio includes axial piston pumps engineered for high-pressure variable displacement applications, steering units for proportional hydraulic steering control, integrated hydraulic brakes with wear-resistant friction materials, and flow dividers that synchronize multiple actuators or wheels to ensure balanced load distribution during vehicle operation.
All White Drive components meet or exceed ISO 1219 fluid power standards and are tested for pressure cycling, thermal stability, and contamination tolerance. Materials include nodular iron, aluminum, and ductile iron castings, with precision honing and seal selection optimized for long service intervals in challenging environments.
Applications span wheel loaders, telehandlers, skid steers, harvesters, compact tractors, and industrial lifting platforms where operator safety and predictable load response are non-negotiable. White Drive's torque multiplication and smooth modulation characteristics make propulsion systems responsive and fuel-efficient.

Frequently asked questions
What's the difference between geroter motors and axial piston motors?
Geroter motors (gear-rotor) are compact, displacement-fixed devices ideal for propulsion where smooth torque and durability matter most. Axial piston motors are variable-displacement, pressure-compensated units offering proportional speed control but are larger and more complex. White Drive specializes in geroters for mobile equipment where simplicity and compactness are advantages.
How do flow dividers ensure synchronized wheel speed in loaders or telehandlers?
Flow dividers split pump flow equally between left and right motor supplies, ensuring both wheels receive identical flow and thus identical wheel speed. This prevents the vehicle from drifting sideways under load and maintains directional control. Without dividers, pressure-relief valve variations can cause asymmetric flow and steering drift.
Can I replace a failed White Drive motor in the field without flushing the hydraulic system?
Not recommended—bearing-wear particles and seal degradation from a failed motor contaminate system fluid. A complete fluid change and filter replacement is essential before installing a replacement motor; otherwise, the new motor will fail prematurely. Budget fluid disposal and replenishment time into your service plan.
What hydraulic fluid viscosity does White Drive specify for cold-climate operation?
Most White Drive equipment uses ISO VG 46 hydraulic oil as baseline. In sub-freezing climates, switch to winter-grade ISO VG 32 or synthetic PAO fluids rated to -20°F or lower. Check your system manual—using the wrong viscosity grade causes sluggish steering response or pump cavitation in extreme cold.
How do I troubleshoot jerky steering or loss of directional control with White Drive steering units?
Common causes: air in the system (bleed the steering circuit), worn spools or seals (requires factory service), or flow-divider imbalance. Start by checking system pressure with a gauge and confirming flow equal to the pump specification. If pressure and flow are normal but steering remains erratic, the steering unit itself likely needs factory-level repair or replacement.
