4. Check the supply pressure of the control valve.
Disconnect one of the hoses connected to the con-
trol valve housing block (blade). Fit the pressure
gauge to the hose just disconnected. Operate the le-
ver (blade) and check the supply pressure of the
valve.
• If the value indicated is not as below, the housing
block is faulty.
Supply pressure: 20.0 MPa (2900 PSI)
When only “Dozer Blade Lower” is impossible
• Replace the port relief valve in question with a
port relief valve used for a normal arm. If the dozer
blade cylinder operates normally with the re-
placement valve, the port relief valve used on the
dozer blade side is faulty.
5. Check the swivel joint.
a. nspect the spool stroke “A” of the selector on the
swivel joint, and check if the spool is correctly
switched to the blade side.
• Spool stroke “A”......6 mm (0.2 in.)
b. Disconnect the hose between the swivel joint and
the blade cylinder from the cylinder side. Install a
pressure gauge on the hose just disconnected
and operate the lever (blade).
• If the value indicated is different from the value
given below, the swivel joint is faulty.
Supply pressure: 20.0 MPa (2900 PSI)
