Detecting cylinder internal leaks
If the packer cylinders are bypassing, the seal inside the cylinders may need to be replaced. If an
internal leak is suspected, apply the following procedure.
To detect internal leaks in packer cylinders:
1. Apply all safety measures and set the parking brake.
2. Pull on the red emergency STOP button.
3. Start the engine and engage the hydraulic pump.
4. Fully extend the packer cylinders, then disengage the hydraulic pump.
5. Disconnect the packer extend proximity switch.
This prevents the packer from returning to its initial position.
6. Disconnect and plug hose “A” (see Figure 5-29).
7. Engage the hydraulic pump.
