Product Description

2401P1279 Swing 2nd Planetary Gear

The 2401P1279 planetary gear is used in the second reduction stage of selected Kobelco excavator swing gearboxes. Four gears operate together in this stage to transfer torque while reducing swing speed.

Its compact 18-tooth profile and relatively deep gear body make correct bore fit, tooth contact and axial alignment important for stable operation under repeated swing acceleration and braking loads.

Check the Gear Bore as Well as the Teeth

Inspect the original gear for chipped teeth, pitting, uneven contact marks and scoring inside the center bore. Excessive bore wear can allow the gear to tilt on its support and create edge loading across the tooth surface.

If one gear is noticeably more worn than the other three, also inspect the carrier support, bearing surfaces and mating gears before reassembly.

Confirm the Early SK200 Swing Gearbox Configuration

Different production ranges can use different internal swing reduction components. Machine model alone should therefore not be treated as the final identification method.

For fitment checking, send the machine model, serial number, swing gearbox information, original gear photos, tooth count, outside diameter, bore diameter and overall gear height.
