The final drive sprocket with part number 208-27-71120 is designed for powertrain systems requiring high torque transmission and durability in the Komatsu crawler excavator series. This component plays a critical role in the reduction gears and final drive mechanisms of heavy-duty construction machinery operating in tough field conditions.
It directly supports power transmission efficiency in the track systems of compatible PC400-7, PC450-7, PC400-8, and PC450-8 series excavators. During part replacement, meticulous inspection of the bearing surfaces and backlash ratios alongside the gear structure is recommended.
- Wear condition of tooth profiles and engagement surfaces
- Shaft fit diameter and tolerance compatibility of keyways
- Lubrication level and contamination control within the final drive housing
You can ensure correct part compatibility by confirming the 2082771120 code using your machine's serial number and corresponding reduction gear group.
