2. check the pilot valve
Disconnect the hose connecting the pilot valve and the
control valve (slew block) from the control valve. Fit the
pressure gauge to the hose just disconnected.
• Insert a plug into the control valve port.
• Operate the lever (slew) and measure the pressure.
• If the pressure is between 0 and 3.4 MPa (0 to 493
PSI) depending on the lever angle, the pilot valve is
normal.
3. check the spool operation
Disconnect the hose connecting the control valve (slew
block) and the slew motor from the control valve. Fit
the pressure gauge to the discharge port on the con
-
trol valve.
• Operate the lever (slew) and measure the pressure.
• If the measured value is as below, the spool is nor
-
mal.
Supply pressure: 20.0 MPa (2901 PSI)
4. check the slew pressure
Measure the pressure at the right and left slew relief
valves.
• If the measured value is within specifications, the
slew pressure is normal.
“2. Service data, Performance criteria”
if the pressure adjustment is possible, the adjustment
of the slew relief valve is faulty. if the pressure adjust-
ment is not possible, the slew relief valve is faulty.
5. check the slew motor
Separate the slew motor (1) from the turntable (2), and
then try turning the turntable (2).
• Does not turn.....The slew bearing (3) is faulty.
• Turns
..................
The slew motor (1) is faulty.
