Reduction ratio matched to PC200-8 working swing speed, providing the correct slew speed and motor load balance for efficient, repeatable dig-and-swing cycles.

All planetary gears carburised to HRC 58-62 for high surface fatigue resistance under the high-cycle PC200-8 swing duty encountered in quarry and demolition applications.

Ring gear and carrier assembled to OEM backlash tolerance, eliminating cab jolt at swing reversal that signals worn planetary mesh.

20Y-26-00230 covers PC200-8, PC200LC-8, PC210-8 and PC220-8 for direct bolt-on replacement.
