Hitachi final drive parts EX60 EX60-1 9069509 hydraulic travel motor for mini excavator

The excavator travel assembly is the core component for machine movement, consisting of a hydraulic motor, reduction gearbox, sprocket, track chain, idler wheel, carrier roller, and track roller. Its key function is to convert hydraulic energy into mechanical power, enabling stable mobility across challenging terrains.

1. Hydraulic Power Transmission

   • The hydraulic pump transforms engine power into high-pressure oil, which is transmitted to the travel motor via hydraulic lines.

   • The travel motor converts hydraulic energy into rotational kinetic energy, generating high-speed, low-torque output.

2. Speed Reduction & Torque Amplification

   • The gearbox reduces motor speed through gear sets while significantly increasing torque, ensuring sufficient traction force for the sprocket.

3. Track Drive Mechanism

   • The sprocket engages with track links to drive the track chain. Carrier rollers and track rollers form a closed-loop track system, while the idler wheel adjusts track tension.

   • Differential control of dual travel motors enables forward/reverse movement, steering, and zero-radius rotation.

Cautions of Final Drive Installation

1. Clean the hydraulic oil circuit, replace the hydraulic oil filter and return oil filter. The mixing of fine particles such as mud, sand or metal powder in the hydraulic oil will wear out motor inner parts too quickly. It is also the main reason for the stuck phenomenon.

2. Check whether the gearbox is filled with gear oil. The volume of the gear oil should be more than half of the total volume of the gearbox. (Generally,factory will add gear oil in final drive )

3. Generally, for a new Chinese made final drive ass'y , it is necessary to replace the new gear oil after using for 7 days or 60 hours for the first time. The second time to change the gear oil is in the 2nd -3rd months. After that, it depends on the usuage situation of the final drive.

4.Try to avoid long-term immersion in water and avoid long-term operation in dusty environment; try to keep the working temperature between -5 to +30 degrees Celsius, avoid extreme cold and hot weather.

5.Difference between the quality of hydraulic oil (motor part) and gear oil (gear box part): Good hydraulic oil and gear oil can extend the service life.

6. Check if the pipeline connection is correct.
