Course: Diesel Equipment Technology III (20107-III) > Section: Hydraulics: Servicing Filtration/Reservoirs (Tanks)

Identification should include

- determining whether the main oil filter is located on the pressure side of the pump or the return side
- checking for the type of filter used
- verifying the application of the filter
- determining the flow direction.

Process/Skill Questions:

- Why do some hydraulic systems have a paper filter and a metal screen in a separate filter base?
- When should a hydraulic oil filter be changed?
- Why are some oil filters placed on the pressure side of the pump while others are placed in the hydraulic tank on the return side?
