Center Joint (Swivel)
TROUBLESHOOTING, TESTING AND ADJUSTMENT
INSPECTION
The center joint should be checked for evidence of external oil leakage every 2,000 hour of operation.
Leaking or defective O-rings 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 change-
over valve.
Install the change over 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
change-over 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).
