Swing slow, noisy or gearbox leaking on your SK60-8 or SK60-10? A worn SK60-8 swing gearbox loses reduction ratio precision, causing cab swing to hesitate and putting shock loads on the swing motor pinion that shorten motor life. RITO supplies this compact multi-stage swing gearbox assembly to restore smooth, torque-stable cab rotation on your Kobelco SK60-series excavator.

In StockSK60-8 Hydraulic Swing Gearbox for Kobelco SK60-8, SK60-10, SK55SRX and SK60SR excavators. Multi-stage planetary reduction gearbox converts high-speed swing motor output into the working slew speed required for the SK60-class upper structure. Heat-treated sun, planet and ring gears, precision carrier pin bores and a factory-controlled backlash assembly ensure smooth, responsive swing from installation.

Multi-stage planetary set provides the high reduction ratio for SK60 working swing speed in the compact housing envelope of the 6-tonne machine without exceeding the slew ring pinion load rating.
All sun, planet and ring gears carburised and case-hardened to HRC 58-62 for the surface hardness required to withstand the millions of swing cycles in typical SK60-series applications.
Carrier and ring gear assembled with controlled backlash to OEM specification, eliminating the cab jolt at swing direction reversal that characterises worn or poorly-assembled replacement gearboxes.
Single assembly covers SK60-8, SK60-10, SK55SRX and SK60SR for direct bolt-on replacement on all current SK60-series variants.
FAQ
Q: What symptoms indicate the SK60-8 swing gearbox needs replacing?
A: Audible gear noise during swing start or stop, cab jolts at swing direction reversal, swing speed slower than specification, gearbox oil leaking from input or output seals, and metal particles visible in gearbox oil on the dipstick.
Q: What gearbox oil should I use in the SK60-8 swing gearbox?
A: Use EP 90 or EP 140 gear oil as specified in the Kobelco SK60-8 service manual. Fill to the sight glass level and change oil at 50 hours after installation to flush assembly residuals.
Q: Can I replace only the worn planet gears in the SK60-8 gearbox instead of the complete assembly?
A: Individual gear replacement requires a gear-cutting facility for matched tooth profile and hardness. For field maintenance, complete gearbox replacement is more reliable and cost-effective, especially when multiple stages show wear.
Q: How to confirm this swing gearbox fits my SK60-8?
A: Verify motor input flange bolt pattern, output pinion tooth count and housing mounting bolt circle match SK60-8 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.

Excavator track adjuster failures often cause costly project downtime. Weak grease valves leak under extreme high pressure, risking master track links throwing off or breaking chains during mining. Avoid sub-par aftermarket parts that ruin heavy machinery and disrupt fleet schedules. 2444P803 solves this entirely.
