RITO 095-1714 Friction Disc 0951714 Center Joint Seal Kit 307 315B 322B 330D Swivel Joint Repair Kit Rotary Sealing Ring Group

Degraded center joint friction discs create internal hydraulic leaks, making the undercarriage track slowly or lose high-speed travel entirely. A faulty rotary manifold wastes engine power, overheats the hydraulic oil, and forces heavy equipment owners into expensive, unplanned teardown maintenance.

RITO 095-1623 Friction Disc 0951623 Center Joint Seal Kit 307 308C 320D 336D Excavator Swivel Joint Repair Kit Rotary Seal Group

Worn center joint friction discs cause internal pressure cross-leaks, making the excavator's tracks drift or lose travel power. For mining contractors, a malfunctioning swivel joint stalls machine mobility, lowers job productivity, and creates severe safety hazards on steep inclines.

RITO 7Y-0465 7Y0465 Coupling Insert 110H Spline 320D 322C 325B 325C Hydraulic Pump Flywheel Power Transmission Coupling Assy

Worn spline inserts slip during high-torque operations, causing sudden hydraulic pressure loss and pump shaft damage. When a coupling element tears in a mining excavator, the entire production line stops, resulting in costly operator downtime and massive repair bills for fleet management.
