What Are Common Failure Parts In An Excavator Travel Motor

Before moving on to prevention let’s name a few common cases of a motor failure. First and foremost you should know that the main bearing is usually the most responsible for a final drive motor failure and that you should replace it as soon as you start hearing more noise or vibration in that area. Making a mistake and leaving the problem unnoticed can cost you a few thousand dollars (cost of a new motor). Along with that, comes the wearing of gears and related bearings as the second most common problem – after years of use gear teeth will be worn out and you should replace it before any further problem occurs. Let’s not forget that upper and lower shafts, along with seals that are leaking are pretty common and something that you should check on a regular basis.

As soon as you hear that your machine is producing more noise than it was before while being less effective it is time to take a look at your motor and see what can be done to save it.

Few Prevention Tips
