Troubleshooting, Testing, and Adjustment

Inspection

Inspect the center joint every 2,000 operating hours for external oil leakage, indicative of potential contamination and accelerated wear. Address any leakage by repairing or replacing worn components.

Testing

To test the pressure through the center joint, assemble a test kit using:

• 700 bar (10,000 psi) pressure gauge.
• Adapters, connectors, and piping conforming to high-pressure connections.
• A high-pressure relief valve with a setting 1.5 times the system’s maximum pressure.
• Stop and changeover valves for manipulating the testing flow.

Use this kit to pressurize the joint above normal working conditions and perform a leak down test by manually securing the stop valve.

NOTE: You can also configure a similar test kit for the drain port side of the center joint using suitable piping and connectors.
