Perbaikan Final Drive Planetary Gear Wheel Loader WA320-3CS

Planetary gear final drive is one of the final driving components and as a connector for the power train component with wheels or tracks. The purpose of this study is to find out the mechanism of action, determine the damage, find out the cause of the damage and know the steps to repair the final drive planetary gear. Procedure for checking final drive planetary gear by performing a performance test, and checking visually, then doing a disassembly to check the components, then analyzing the results of the inspection to determine the damage that occurs in the final drive planetary gear. The results of the analysis show that there are damaged planetary gear final drive components, namely pinion gear, pinion gear bearings, ring gear, driveshaft gear so that the final drive planetary gear cannot work optimally. To find out the cause of damage to the planetary gear final drive, an analysis is calculation on the gear, the corrective steps carried out by replacing damaged components
