How to Confirm the Correct Swing Planetary Gear

Before ordering 20Y-26-22140, we recommend providing the following information:

• Original gear part number

• Excavator model

• Machine serial number

• Swing gearbox or reducer assembly number, if available

• Clear photos of the removed gear

• Tooth count and key dimensions when the original number is unclear

Checking these details helps avoid incorrect selection when different swing gearbox versions are used within the same excavator model series.

When Should a Swing Planetary Gear Be Replaced?

Planetary gears inside the swing reducer should be inspected whenever abnormal swing gearbox noise, excessive backlash or internal metal contamination is found.

Replacement may be required when inspection identifies:

• Broken or chipped gear teeth

• Abnormal tooth surface wear

• Pitting or scoring on the gear teeth

• Excessive backlash inside the swing reducer

• Damage caused by bearing or carrier failure

• Metal particles found in swing gearbox oil

When replacing a damaged planetary gear, inspect the mating gears, carrier, pins, bearings and swing reducer housing at the same time to prevent repeat failure.
