What Does This Operating Rod / Joystick Do?
The pilot pressure control assembly that translates operator lever movements into proportional hydraulic pilot signals. These signals are sent to the main control valve spool to direct boom, arm, bucket, and attachment movement with precision.
Possible Operating Rod / Joystick Problem Symptoms
If your machine is showing any of the following, a faulty operating rod / joystick may be the cause:
- Boom, arm, or bucket moving only in one direction despite full lever travel
- Jerky or non-proportional movement response to lever input
- Pilot oil leaking from the joystick assembly body or fittings
- Hydraulic function running at full speed regardless of how gently the lever is moved
