If a standard excavator has lost tractive effort and travel speed, a worn R485VS R480-9R520-9 Travel Reduction Gearbox is the most common cause. The reduction gear set is the highest load point in the travel circuit, so any slack in the bearings shows up immediately as noise, heat and lost speed. RITO keeps this R485VS R480-9R520-9 Travel Reduction Gearbox in stock as a sealed, pre-assembled replacement.
