Gear, Drive & Ep oils perform several crucial tasks, they provide
the required lubrication and heat transfer in the compartments to
achieve optimum performance. The following Gear, Drive & EP
schedules have been derived. Scheduled oil analysis is the best way to
maintain the balance between the premature and reactive maintenance.
Testing Levels
|
| Level 1 |
Used
when there is no apparent concern due to contamination or wear. A basic
analysis that serves as a useful tool to obtain an overall veiw of the
compartment.
|
Level 2
|
When issues arise with the performance of the compartment and the oil.
|
Level 3
|
This
level of testing gives you key performance indicators of the oil and
the compartment. Best suited for warranty purposes. This level of
testing will comply above and beyond any OEM's requirements.
