Oil seals are used on the final drive motor axle to keep the gear oil for the planetary gear set or bearings from mixing with hydraulic oil. These seals are vital to the operation and performance of your final drive motor -- and learning how they can fail is essential.

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
Crushing accidents don’t just happen when someone gets run over by equipment -- they can also occur when you’re working on your equipment and don’t take hazardous energy into account.
