A standard excavator that swings or travels slowly, whines under load or leaks oil from the travel reduction hub is usually telling you the EX100-1 EX120-1 Travel 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 EX100-1 EX120-1 Travel Gearbox as a ready-to-fit assembly, so the machine is back to full tractive effort and travel speed without a rebuild.
