A standard excavator that swings or travels slowly, whines under load or leaks oil from the swing reduction hub is usually telling you the VOLVO EC700 Swing Reduction Gearbox has reached the end of its service life. Worn planet gears, a scored ring gear and a failed bearing set all waste torque before it reaches the track or the upper structure. RITO supplies this VOLVO EC700 Swing Reduction Gearbox as a ready-to-fit assembly, so the machine is back to full swing torque and swing speed without a rebuild.
