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.

Mechanical stress is behind any of the failures we encounter when inspecting a final drive motor. Sheared fasteners, bent gear teeth, dented roller bearings, and broken races are examples of where stresses have gotten high enough to do permanent damage. To help you learn more about the mechanisms behind this and other types of failure, we'd like to introduce you to a new blog series entitled Dr. Mac's Notebook.

Simple Forces

There are three basic types of forces:

  • Compressive, which pushes things together
  • Tensile, which pulls things apart
  • Shear, which causes things to slide apart

When we hear the word “leak” or “leakage” in reference to a final drive motor, our knee-jerk reaction is to assume it's something bad. In a hydraulic system, though, internal leakage is good -- up to a certain point.
