Medium Dozer Final Drive Group 265-2299 For Tractor D6T LGP

The final drive group is a critical component in a medium dozer’s undercarriage and powertrain system, responsible for transferring power from the transmission to the tracks, enabling movement, pushing, and heavy-load operations. It plays a vital role in the machine’s efficiency, durability, and overall performance.

Power Transmission & Torque Multiplication

Converts high-speed, low-torque input from the transmission into low-speed, high-torque output to drive the tracks.

Essential for pushing heavy loads, climbing slopes, and operating in tough terrain.

Track Movement & Steering Control

Works in conjunction with the steering clutch and brakes (if equipped) to control track speed and direction.

Allows for smooth turns and precise maneuverability.

Load Distribution & Shock Absorption

Handles the weight of the dozer and external forces from digging, pushing, and uneven ground.

Helps absorb impacts, reducing stress on other drivetrain components.

Efficiency & Fuel Economy

A well-maintained final drive ensures optimal power transfer, minimizing energy loss and improving fuel efficiency.

Planetary Gear Reduction System – Steps down speed while increasing torque.

Final Drive Sprocket – Engages with the track chain to propel the dozer.

Bearings & Seals – Support rotational movement and prevent contamination.

Hub & Flange Assembly – Connects the final drive to the track frame.

Lubrication System – Ensures smooth operation and reduces wear.

✔ Durability in Harsh Conditions – Designed to withstand heavy loads, mud, rocks, and abrasive materials.
✔ High Torque Demand – Dozers require massive pushing force, making the final drive’s torque multiplication essential.
✔ Undercarriage Longevity – A failing final drive can cause uneven track wear, sprocket damage, or complete undercarriage failure.
✔ Minimized Downtime – Proper maintenance prevents costly breakdowns during critical operations.
