Here is some information about the Hitachi EX120 final drive:eCLR

1. Function: The final drive is the last stage in the power transmission system of the excavator. It receives power from the engine and hydraulic system and transfers it to the tracks, driving the excavator forward or backward. It consists of a motor, gear reduction mechanism, and planetary gear sets.eCLR

2. Design: The final drive is typically located on each side of the excavator, attached to the undercarriage. It is designed to withstand the high torque and load generated during excavator operation. The motor within the final drive converts hydraulic pressure into rotational force, which is then transmitted through the gears to drive the tracks.eCLR

3. Components: The main components of the final drive include the hydraulic motor, gears, bearings, seals, and housing. These components work together to provide reliable power transmission and ensure smooth and efficient operation of the excavator.eCLR

4. Maintenance and Repair: Proper maintenance and regular inspection of the final drive are essential to ensure its optimal performance and longevity. This includes monitoring the hydraulic fluid levels and quality, checking for leaks, inspecting seals and bearings, and maintaining the recommended maintenance intervals. If the final drive requires repair or replacement, it is recommended to consult the manufacturer's documentation, contact Hitachi or an authorized dealer, or seek assistance from a qualified technician to ensure the appropriate repair or installation.eCLR

It's important to note that the specific details of the Hitachi EX120 final drive, including its design, specifications, and maintenance requirements, may vary depending on the excavator's model, series, and production year.
