Product Overview
This Parker TF series Torqmotor™ medium-duty low-speed high-torque hydraulic motor is a direct drop-in replacement, specifically covering TF0080 through TF0475 displacement configurations. It perfectly replaces Parker TF series original motors while being compatible with White RE series and M+S MT series equivalents.
The TF series features a high-strength cast iron housing and patented 60:40 spline geometry for superior drivetrain strength. All spline teeth are continuously flushed with cool fluid for durability. The motor is equipped with a high-pressure shaft seal capable of withstanding full system pressure without external case drain lines. Every unit undergoes 100% simulated working-condition bench testing before shipment, verifying that displacement, pressure, torque, and speed characteristics fully match original Parker specifications.

Key Technical Advantages
1. Patented 60:40 Spline Geometry
The TF series powertrain uses Parker’s patented 60:40 spline geometry, offering higher root strength and shear resistance compared to conventional splines. All spline teeth are continuously flushed with cool fluid, reducing wear rates and significantly extending drivetrain component life under heavy-load conditions.
2. Roller Vane and Sealed Commutation Technology
The roller vane rotor set with sealed commutation valve provides built-in wear compensation, ensuring high volumetric efficiency. The zero-leak commutation valve delivers greater torque and speed output while maintaining smooth low-speed operation, with stable speeds achievable below 1 rpm.
3. High-Pressure Shaft Seal with No Case Drain Required
The standard high-pressure shaft seal withstands full system pressure (up to 300 bar). The innovative design requires no external case drain lines, simplifying installation and reducing system costs. Continuous oil flow washes and cools the shaft seal, extending seal life and reducing maintenance frequency.
4. Superior Side Load Capacity
Flange mount configurations handle side loads up to 17,792 N, while wheel mount configurations reach 26,688 N. The heavy-duty bearing system combined with a reinforced output shaft makes the TF series ideal for chain-and-sprocket drives and direct wheel mounting applications without additional support structures.
5. Modular Clutch Option
The TF clutch series provides an industry-unique solution for applications not requiring continuous power output. When no pressure is applied at motor ports, springs separate the motor from the output shaft, allowing free rotation. Pressure at either port compresses the springs, coupling the motor to the shaft. This design is particularly suited for tractor winches, free-wheeling drives, and similar applications.
6. Wide Displacement Coverage and High Power Density
The TF series covers 11 displacement configurations from 81 to 477 cm³/rev, with maximum output power of 27.7 kW (37.1 HP). The compact lightweight design (14.0–17.5 kg) delivers maximum torque output within limited installation space.

Expert Maintenance Tips
Installation:
Verify that flange pilot, shaft spline dimensions (1-1/4″ 14 Tooth), and port specifications (7/8-14 SAE) precisely match the original Parker TF series. The TF0240MB050AAA magneto mount interface is directly interchangeable.
Ensure spline teeth are clean and undamaged before installation. Apply a small amount of hydraulic oil to lubricate splines before assembly.
Prime the housing with clean hydraulic oil before first startup. Perform a 30-minute run-in at 30% maximum working pressure before full-load operation.
Operation & Maintenance:
Use ISO VG 46 anti-wear hydraulic oil with cleanliness no lower than NAS Class 9 or ISO 18/15.
The TF series requires no external case drain, but if an external drain line is used, return back pressure must not exceed 5 bar.
Regularly inspect shaft seal condition. Replace promptly if leakage is detected. Perform a 30-minute no-load run-in after seal replacement.
Inspect spline wear every 2,000 operating hours or annually. Replace if pitting or significant wear is observed.
Maintain oil temperature below 80°C, with maximum not exceeding 82°C.
Under intermittent conditions, running time must not exceed 10% per minute. Avoid simultaneous operation at maximum pressure and maximum speed.
