Swing speed slow, noisy or inconsistent on your SK200-8? A worn SK200-8 swing gearbox loses reduction ratio accuracy, making precise cab positioning difficult and putting shock loads on the swing motor. RITO's hydraulic swing gearbox assembly restores full torque reduction and smooth slewing on your SK200-8.

In StockSK200-8 Hydraulic Swing Gearbox for Kobelco SK200-8 excavator. The swing gearbox is a multi-stage planetary reducer between the hydraulic motor and the swing pinion; its condition determines swing precision, cycle time and motor service life. RITO assembles this gearbox with heat-treated planetary gears, a precision-bored carrier and a matched ring gear for zero-backlash output from day one.

Two or three-stage planetary set delivers the high reduction ratio required to convert the high-speed low-torque swing motor output into the low-speed high-torque pinion drive.
All sun, planet and ring gears carburised and case-hardened to HRC 58-62, providing the surface hardness needed for millions of swing cycles without tooth-flank pitting.
Planet carrier and ring gear assembled with controlled backlash to OEM specification, eliminating the cab jolt at swing direction reversal that characterises worn gearboxes.
Complete assembly dimensionally matched to SK200-8 swing motor output flange and slew ring mounting bolt circle for direct bolt-on replacement.
FAQ
Q: What are the signs that the SK200-8 swing gearbox needs replacing?
A: Audible gear noise during swing, cab jolts at swing start and stop, difficulty holding a steady swing speed, metallic particles in swing gearbox oil, and oil leaking from the gearbox input or output seals.
Q: Can I replace individual gears inside the SK200-8 swing gearbox?
A: Individual gear replacement is possible but requires a gear-cutting facility to match tooth profile and hardness. For field maintenance, complete gearbox replacement is more reliable and cost-effective, particularly when multiple gear stages are worn.
Q: Does the SK200-8 swing gearbox require a specific oil type?
A: Kobelco SK200-8 swing gearbox typically uses EP 90 or EP 140 gear oil. Fill to the specified level marked on the gearbox housing and change oil at the first 50-hour interval after installation to flush any assembly debris.
Q: How to confirm this swing gearbox fits my SK200-8?
A: Verify the motor output flange bolt pattern, swing pinion shaft diameter and gearbox housing mounting bolt circle match the SK200-8 specification. Provide the machine serial number to our team for confirmation.
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.
