The part numbered 22U-27-21153 is one of the essential components ensuring torque transmission in the undercarriage mechanisms of crawler heavy machinery. Fully compatible with PC220-7, PC220-8, PC228-3, PC230-7, and PC240-8 series excavator models, this final drive ring gear supports the efficient operation of powertrain components under severe field conditions. During part replacement, tightening the flange connection bolts to the correct torque values and cleaning the gear housings are crucial for the service life of the drivetrain.
Final Drive Gear Inspection
When performing wear checks on heavy equipment travel reducers, the contact surfaces between the internal tooth profile of the gear coded 22U2721153 and the pinion gear must be thoroughly examined. In such planetary and ring gear systems operating under heavy loads, regular monitoring of the lubrication level is among the factors that directly affect gear lifespan.
