TE0165CW260LAAY Parker Motor | 190 Bar LSHT 436 Nm

Product Overview

The TE0165CW260LAAY is a 163 cm³/rev displacement model from Parker’s Torqmotor™ TE Series of low-speed high-torque (LSHT) hydraulic motors, belonging to the medium-duty motor product line. The TE Series is the only motor in its class featuring roller bearing construction, capable of handling dynamic side loads up to 6,672 N (1,500 lb) and specifically engineered for chain and sprocket coupling applications subjected to shock loading.

The model code breaks down as follows: TE identifies the Torqmotor TE Series; 0165 denotes the 163 cm³/rev displacement; CW indicates clockwise rotation; 260 is the shaft and mounting configuration code; LAAY denotes additional options including port configuration, paint and shaft seal type. The manufacturer part number is B92.03773, and this model serves as an OEM motor on GRIMME agricultural machinery platforms.

The TE Series employs an orbital (Gerotor) hydraulic motor design, delivering high starting torque, smooth extra-low-speed operation, and a high-pressure shaft seal. Its innovative design eliminates the need for a case drain, removing additional plumbing requirements and simplifying system integration. Continuous oil flow across internal splines provides cooling for extended motor life.

Every TE0165CW260LAAY unit undergoes 100% simulated operating-condition bench testing prior to shipment. Mounting flange, shaft end and port dimensions comply with SAE standards and are identical to the original Parker TE0165 series, ensuring true drop-in interchangeability with zero modification required.

Key Technical Advantages

1. Only Roller Bearing Design in Class for High Side Load Capacity

The TE Series is the only hydraulic motor in its class featuring roller bearing construction, capable of handling dynamic side loads up to 6,650 N (1,500 lb). This enables the TE0165CW260LAAY to directly withstand shock loads delivered by chain and sprocket couplings without additional bearing support or alignment mechanisms, significantly simplifying drivetrain design and reducing installation and maintenance complexity. The cast iron housing provides excellent rigidity and heat dissipation.

2. High Starting Torque and Smooth Extra-Low-Speed Operation

The TE Series orbital motor delivers high starting torque—up to 338 N·m (intermittent) at startup—ensuring reliable starting under load. The motor supports smooth extra-low-speed operation without stick-slip, making it particularly suitable for applications requiring precise speed control such as conveyor drives and rotary positioning systems. Maximum intermittent torque reaches 436 N·m with maximum power of 17.0 kW, delivering excellent torque density among comparable LSHT motors.

3. Innovative Design Eliminates Case Drain Requirement

The TE Series employs an innovative design that eliminates the need for a case drain line. This simplifies hydraulic system plumbing, reduces installation complexity, and minimizes potential leak points. System integration is cleaner and maintenance is easier. This advantage is particularly significant in space-constrained installations.

4. High-Pressure Shaft Seal and Continuous Spline Cooling

The TE0165CW260LAAY features a high-pressure shaft seal as standard, enabling reliable operation under high back-pressure conditions. Continuous oil flow across internal splines ensures that spline connections remain adequately lubricated and cooled, effectively extending the service life of critical moving components. The 7/8-14 SAE straight thread O-ring boss ports provide reliable and straightforward installation.

5. 100% Simulated Load Testing & Drop-In Interchangeability

Each TE0165CW260LAAY unit is bench-tested under simulated operating conditions prior to dispatch, covering pressure cycling, speed stepping and torque output. Mounting flange, shaft end and port dimensions comply with SAE standards, matching the original Parker TE0165 series exactly, enabling direct replacement without pipework or interface modification. This model serves as an OEM motor on GRIMME agricultural machinery platforms, validating its interchangeability and reliability.

Application Areas

The TE0165CW260LAAY is deployed across a wide range of applications:

• Turf & Landscape Equipment: zero-turn radius mowers, golf course maintenance equipment, fairway rollers

• Aerial Equipment: scissor lifts, aerial work platforms

• Agriculture: combine harvester header drives, augers, planters, specialty harvesters (potato, tomato, nut, leafy vegetable, sugar, cotton, coffee, grape), GRIMME potato harvesters

• Material Handling: conveyors, winches, augers, chain drives

• Municipal Equipment: sweepers, snow removal, salt and sand spreaders

• Construction: mini skid steer attachments, wood chippers

• Industrial: portable irrigation systems, oil and gas blender trucks, bulk feed trucks

Expert Maintenance Tips

1. Side Load Control and Coupling Alignment: The TE0165CW260LAAY has a maximum dynamic side load of 6,650 N (1,500 lb) measured at the key. Ensure chain or sprocket coupling alignment deviation does not exceed 0.05 mm during installation to prevent abnormal roller bearing wear from misalignment. Periodically inspect key connections; excessive key clearance amplifies side load impact. Inspect roller bearing operating condition every 2,000 hours.

2. Maintenance of No-Case-Drain Design: The TE Series requires no case drain line, but system design must ensure the motor housing drains naturally through internal passages. If the motor is installed in a high back-pressure return line, verify back pressure does not exceed the motor’s maximum allowable case pressure (1.7 bar continuous, 5.2 bar maximum). Periodically inspect shaft seal condition and replace the high-pressure shaft seal if leakage is detected. According to the Parker Torqmotor service manual, oil seal aging and loose hose fittings are common causes of leakage.

3. Port Connection and Seal Inspection: This model features 7/8-14 SAE straight thread O-ring boss ports. Use SAE J1926 compliant O-rings during installation and tighten to Parker technical manual torque values. Periodically inspect port connections for leakage, especially under frequent pressure cycling conditions. If insufficient oil supply or high internal leakage is observed, inspect port seals for integrity.

4. Oil Cleanliness and Temperature Control: Maintain system oil cleanliness at ISO 4406 18/16/13 or better. Operating oil temperature should be kept below 80°C. Replace hydraulic oil and filter after the first 500 hours, then follow a 2,000-hour or annual replacement cycle. VG 46 is recommended at 60°C operating temperature.

5. Housing Priming and First Startup: Before first startup, fill the motor housing with clean hydraulic oil (VG 46 recommended) through the drain port. An unprimed housing causes dry friction at startup, severely damaging the piston group and distribution mechanism. After extended shutdown, fill the housing again before restarting. Apply appropriate grease to spline connections during installation.

6. Troubleshooting and Periodic Inspection: According to the Parker Torqmotor service manual, common issues include oil leakage, insufficient oil supply and reduced output torque. Troubleshooting should sequentially check: hose fittings for looseness or damage, O-rings for heat-related deterioration, and internal shaft seals for wear. Abnormal noise, vibration or efficiency loss requires immediate shutdown and service. Use Parker original specification parts when replacing seals to ensure fit accuracy and assembly torque per technical manual requirements.
