If a standard excavator has lost tractive effort and travel speed, a worn ZX650-3 ZX670-3 Travel Motor 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 ZX650-3 ZX670-3 Travel Motor in stock as a sealed, pre-assembled replacement.
