We know we harp on about maintenance for your final drive motors, but there's a great reason why: we know that your final drive will last years longer if you take care of it.  Repairs and replacements are not only expensive, but also lead to downtime, missed deadlines, and frustration . A few hours a year can save you a few weeks of lost time when your final drive breaks down unexpectedly! And it will break down, if you don't take care of it.  In this Shop Talk Blog post, we are going to talk about three key tasks that can help you keep the final drive on your hydraulic excavator running efficiently .
