BUCKET
3. Inspect movement of the spool.
a. Disconnect one of the hoses connected to the
bucket section of the control valve.
b. Fit a pressure gauge to the bucket section.
c. Engage the lever to operate the bucket cylin-
ders and measure the pressure.
• The spool is working properly if the pressure
is within the specified values.
4. Perform replacement test for the port relief
valves.
Replace the port relief valve for the lift arms
with a working one and see if the bucket cylin-
ders then operates properly. If they do, the port
relief valve for the bucket may be judged to be
at fault.
5. Inspect the bucket cylinders.
a. Disconnect the hoses connected to the bucket
section of the control valve.
b. Connect the hoses to the auxiliary section.
c. Try moving the bucket cylinders. The cyl-
inders may be assumed to be not working if
they fail to move here.
Always be sure to lower the lift arms and
bring the bucket down and into contact
with the ground before beginning the above
procedure.
