2413N462F1 Swing 1st Planetary Carrier Assembly for Kobelco Excavator SK200-1 SK200-3 SK200LC SK210

2413N462F1 Swing 1st Planetary Carrier Assembly

The 2413N462F1 planetary carrier assembly is used in the swing reduction gearbox of selected Kobelco excavators. Its open four-planet design supports the planetary gears and keeps them correctly positioned while swing motor torque passes through the reduction system.

This carrier is designed for a specific reduction-stage position. Similar Kobelco swing carriers may use a different body structure, center drive profile or gear arrangement, so appearance alone should not be used to confirm interchangeability.

What to Check During Swing Gearbox Repair

Check the four planetary gear positions for uneven wear or excessive movement. Also inspect the center drive area, gear support surfaces and carrier body for cracks, deformation or abnormal contact marks.

If one planetary gear shows much heavier wear than the others, inspect the associated support, bearing surfaces and mating gears before installing a replacement carrier.

Confirm the Original Carrier Before Ordering

For older excavators, the installed swing reducer may have been replaced during previous repairs. Machine model alone is therefore not always enough to confirm the correct carrier.

Send the excavator model, machine serial number, swing gearbox information, photos of both sides of the original carrier, overall dimensions and center drive details for comparison.

These checks help distinguish first-stage and second-stage carrier assemblies before shipment.
