Swing backlash increasing or gearbox oil leaking on your EC210B? A worn 14516445 swing gearbox loses planetary mesh precision, causing the cab to jolt at direction reversals and shortening swing motor life. RITO supplies this robust swing gearbox assembly to restore precise, backlash-controlled cab rotation on your Volvo EC210B.

Reduction ratio matched to EC210B working swing speed, delivering smooth, controlled cab rotation without over-revving the swing motor during fast swing cycles.

Sun, planet and ring gears carburised and case-hardened to HRC 58-62, providing the surface fatigue resistance needed for Volvo EC210B high-cycle swing duty.

Carrier and ring gear assembled to OEM backlash spec, eliminating the cab jolt at swing reversal that indicates gearbox wear on high-hour EC210B machines.

14516445 covers EC210B, EC210BL, EC210 and EC240B for direct bolt-on replacement without gearbox housing modification.

FAQ
Q: How to distinguish 14516445 gearbox failure from swing motor failure on EC210B?
A: Test swing motor case-drain flow. Normal drain flow with gear noise and metal in gearbox oil confirms gearbox failure. High case-drain flow above OEM spec confirms motor wear rather than gearbox.
Q: What gear oil volume is required for 14516445 on EC210B?
A: Fill to the level mark on the gearbox housing sight glass using EP 90 or EP 140 gear oil. Drain and refill after the first 50-hour break-in period.
Q: Does 14516445 gearbox fit EC240B without modification?
A: Yes. 14516445 covers EC240B in addition to EC210B-series. Confirm motor input flange bolt pattern and output pinion specification match EC240B before ordering.
Q: How to confirm 14516445 fits my EC210B?
A: Match part number 14516445 and confirm machine is EC210B, EC210BL or EC240B. Provide 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.
