Swing speed reduced or gearbox leaking on your Hyundai 160LC-3? A deteriorated RG10D20C1 swing gearbox loses planetary gear mesh quality, causing swing hesitation and increasing the shock loads that eventually damage the swing motor pinion. RITO's robust swing gearbox assembly brings back precise, responsive cab rotation on the 160LC-3.

In StockRG10D20C1 (29B1 435) Swing Gearbox for Hyundai 160LC-3 excavator. This compact multi-stage planetary reducer converts swing motor speed to working slew speed while multiplying torque to overcome upper structure inertia. Precision planet pin bores, heat-treated gear elements and an integral input seal protect the gearbox against the high-cycle fatigue of excavator swing duty.

Two-stage planetary set achieves the reduction ratio required for 160LC-3 swing speed in a compact envelope that fits directly within the OEM housing dimension.
Planet carrier pin bores case-hardened and precision-bored to H7, maintaining correct planet gear mesh centre distance under the full working torque of the 160LC-3 swing circuit.
Factory-installed input shaft lip seal prevents swing gearbox oil from contaminating the swing motor while excluding hydraulic oil from the gearbox oil circuit.
Motor flange bolt pattern and pinion spline specification matched to 160LC-3 OEM for drop-in installation without gearbox housing modification.
FAQ
Q: What symptoms indicate the RG10D20C1 gearbox needs replacing on my 160LC-3?
A: Swing speed is noticeably slower than normal, there is a grinding or whining noise during swing, oil leaks from the gearbox housing or input seal, and metallic particles are visible in the gearbox oil on the dipstick.
Q: Do I need to replace the swing motor when replacing the RG10D20C1 gearbox?
A: Not necessarily. First check swing motor case-drain flow. If within spec, the motor can remain. However, if the gearbox failed by tooth fracture and the debris contaminated the motor, motor inspection is essential before refitting.
Q: What gear oil should I use in the RG10D20C1 after installation?
A: Use EP 90 or EP 140 gear oil as specified in the Hyundai 160LC-3 service manual. Fill to the level mark on the gearbox housing and drain after the first 50-hour break-in period to flush any residual assembly particles.
Q: How to confirm RG10D20C1 fits my 160LC-3?
A: Match the motor input flange bolt pattern, housing mounting bolt circle and output pinion spline specification. Provide the machine serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
