SWIVEL JOINT 4O0AX00
Inspection after assembly
After assembly, perform an oil leak test on each circuit
using the apparatus shown in the figure.
1. Connect the pipe (3) from the hydraulic pump (2) to
the shaft (1) side port.
2. Connect the pressure gauge (5) to the hub (4) side.
• Increase the pressure gradually to 20.6 MPa (2900PSI)while
adjusting the relief valve (6). Perform the leak test
for one minute.
• Open the neighboring ports on both sides and vi-
sually check for leaks from the ports.
• Perform a color check to detect external leaks.
