Swing response on your R210LC-3 feels sluggish or the gearbox makes a grinding noise that gets louder over time? A deteriorated R210LC-3 swing reduction gearbox loses gear mesh accuracy, reducing swing speed and putting progressive shock load on the swing motor output shaft. RITO's robust swing gearbox assembly restores full, smooth-torque cab rotation.

In StockR210LC-3 Swing Reduction Gearbox for Hyundai R210LC-3 excavator. 14-tooth pinion output, 12-bolt motor flange, 9.5 cm bolt spacing. The gearbox converts the high-speed low-torque hydraulic motor output into the low-speed high-torque pinion drive required to slew the R210LC-3 upper structure at working speed. Heat-treated planetary stages and precision carrier pin bores minimise backlash at the pinion output.

Pinion tooth count and module matched to R210LC-3 slew ring internal gear for correct swing speed and smooth, gap-free mesh at the ring gear engagement point.
Motor input flange bolt circle confirmed at 12 bolts on 9.5 cm pitch to match R210LC-3 Hyundai swing motor output shaft specification.
Two-stage planetary set delivers the high reduction ratio required for R210LC-3 working swing speed in a compact, sealed housing.
Input shaft lip seal and output pinion shaft seal prevent gearbox oil loss and hydraulic oil ingress from the swing motor case, protecting gear life.
FAQ
Q: What are the signs that the R210LC-3 swing gearbox needs replacing?
A: Audible gear noise during swing start or stop, cab jolts at swing direction reversal, swing speed progressively slower than specification, oil leaking from input or output seal, and metal flakes in gearbox oil.
Q: What is the correct gearbox oil volume for the R210LC-3 swing gearbox after installation?
A: Fill the gearbox to the level mark on the housing sight glass using EP 90 or EP 140 gear oil as specified in the R210LC-3 service manual. Drain and refill after the first 50-hour break-in period.
Q: Can I replace the R210LC-3 swing gearbox without removing the swing motor?
A: The swing motor must be disconnected from the gearbox input flange to remove the gearbox. Inspect the motor output shaft for fretting or scoring before reattaching to the new gearbox.
Q: How to confirm this gearbox fits my R210LC-3?
A: Verify 14-tooth pinion, 12-bolt motor flange at 9.5 cm bolt pitch, and housing mounting dimensions match R210LC-3 specification. Provide machine serial number for confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
