Doosan DX210W Manual Instruction Extract:

Inspection
The center joint should be checked for evidence of external oil leakage every 2,000 operating hours. Leaking or defective Orings are an indication that dirt and other contaminants could be getting inside the assembly, which will promote accelerated, abnormal wear and may cause early failure of the assembly.
If internal seals or other sliding surface components are worn and there is internal fluid leakage, complete overhaul and repair or replacement of the center joint may be required.

Testing
To check pressure through the center joint, make up a test kit from the following equipment list:
• 700 bar (10,000 psi) pressure gauge.
• Adapters, connectors, piping and flange block-off plates conforming to those used in high-pressure piping connections of the excavator.
• A high-pressure relief valve with a setting pressure 1.5 times maximum system pressure.
• A stop valve.
• A manually operated, in-line changeover valve.

Install the changeover valve upstream from one of the stem high-pressure ports. Connect the pressure gauge downstream from one of the body ports. Install the stop valve between the changeover valve and the stem of the center joint. Other components should be installed according to the layout in the block diagram. The test kit is used to pressurize the center swivel above normal working pressure and lock in the higher pressure (as the stop valve is closed manually) for a leak down test.

NOTE: The same type of kit can also be made up for the drain port (return line) side of the center joint. Use appropriate piping, connectors, test gauges, etc., and follow the same block diagram general layout (Figure 2).
