Title: Identify the cause of incorrect actuator movement and leakage (i.e., internal/external).
Course: Diesel Equipment Technology III (20107-III) > Section: Hydraulics: Servicing Actuators

Identification should include

- performing a visual check and operational test to isolate actuator leakage problems
- determining any needed action.

Process/Skill Questions:

- What would cause an actuator to move down when the control lever is in the hold position?
- What is the major cause for internal seal wear?
