c. Raise the dozer boom and apply a load on the
blade.
• If the machine drops while oil drains from the
cylinder’s piping, the cylinder is faulty.
If the machine drops even though no oil drains
out, the control valve or the swivel joint is faulty.
If the machine cannot be supported by the
blade, try replacing the port relief valve with a
normal one. If the blade can support the ma-
chine after this replacement, then the port relief
valve is faulty.
3. Inspect the swivel joint and the control valve.
Disconnect the hose connecting the swivel joint and
control valve from the control valve. Insert a plug into
the hose just disconnected.
Apply a load to the blade by following the steps 2 (a)
through (c) above.
If the machine drops, the swivel joint is faulty.
If the machine does not drop, there is a leak inside
the control valve.
