Instruction Extract

Inspection

The center joint must be checked for any signs of external oil leakage every 2,000 operating hours. Leaking or faulty O-rings may indicate contamination inside the assembly that can lead to excessive wear or early failure. In such cases, thorough overhaul, repair, or replacement is recommended.

Testing

For pressure testing through the center joint, create a test kit using the following components:

• 700 bar (10,000 psi) pressure gauge
• Adapters, connectors, and flanges matching high-pressure piping of the excavator
• High-pressure relief valve set to 1.5 times the maximum system pressure
• Stop valve and manually operated changeover valve

Install the changeover valve upstream from a high-pressure port, connect the pressure gauge downstream from a body port, and set up the remaining components according to the block diagram workflow. This setup assists in pressurizing and testing the center joint for leakage.

Note: Similar setups can be devised for other components, including the drain port side.
