Cab rotation slow or jerky on your SH200-5? A worn SH200-5 swing gearbox allows backlash to grow at each planetary stage, making precise cab positioning difficult and increasing the shock reversal loads that shorten swing motor life. RITO's robust swing gearbox assembly eliminates that backlash and restores precise slewing on the SH200-5.

Motor flange bolt pattern and output pinion spline matched to SH200-5 OEM for drop-in replacement without housing modification.
FAQ
Q: What symptoms indicate the SH200-5 swing gearbox needs replacing?
A: Swing speed fluctuates across the rotation arc, gear noise increases during deceleration, the cab jerks noticeably when reversing swing direction, and gearbox oil shows bronze or steel metallic debris.
Q: What is the Sumitomo-recommended gearbox oil change interval for SH200-5?
A: The Sumitomo SH200-5 service manual typically specifies initial gearbox oil change at 250 hours and every 1000 hours thereafter. Drain and replace oil with the correct EP grade after fitting a new gearbox at the 50-hour mark.
Q: Is the SH200-5 swing gearbox interchangeable with SH200-3 or SH200-6 variants?
A: Not directly. Different SH200 generations may differ in motor flange bolt pattern or gear ratio. Confirm the model and serial number before ordering.
Q: How to confirm this swing gearbox fits my SH200-5?
A: Verify motor flange bolt count and pitch, output pinion tooth count and housing mounting bolt circle against SH200-5 OEM data. 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.
