Failure in a final drive motor is always bad -- but a good understanding of basic metal failure can help understand what causes it and lead to a better understanding of metal behavior in general.

In this Shop Talk blog post, you'll learn about basic metal failure and the material properties that explain it. This includes an introduction to tensile testing, a discussion of key metal parameters, and an example of how these parameters can vary.

Of course, there are obvious signs of hose failure: fluid spewing from a crack, a hose split wide open, or a hose blown off a connector. However, there are several signs you can look for that tell you failure is imminent -- and that’s the blog post's topic.

You’re in the field working on a job with a tight deadline when the lifting arm on your skid steer or boom on your compact excavator suddenly loses power. You step out of the machine and see the cause: a leaking hydraulic hose. While you may not know what’s happening inside a hydraulic hose, some signs on the outside can serve as a red flag to replace (and maybe reroute) that hose. Here's a discussion on what to look for during your daily equipment walkaround.
