A.
Problem
- Cylinder rod seal
leaking
If when operated, cylinder loses fluid around rod, rod
seal is leaking.
Solution for Faulty Cylinder Rod Seal
Replace cylinder rod seal, using kit available from
your RAYCO distributor.
B.
Problem
- Cylinder piston seals
leaking
To determine if cylinder piston seals are leaking,
perform a hydraulic pressure check of the cylin-
ders circuit.
Please take note of danger of fluid penetra-
tion given in the Safety / General Hazard In-
formation section. Improperly tightened fit-
tings can result in dangerous leaks.
Whenever changing fittings, the engine must
be turned OFF and the internal pressures
relieved, to avoid dangerous high pressure
leaks at loosened fittings.
A liquid filled pressure gauge capable of withstanding
up to 3000 PSI should be installed by inserting a T-
fitting into the high pressure port (see above) of the
hydraulic cylinders pump. Insert the gauge into one
opening of the T-fitting and reconnect the high pressure
hose to the other opening.
With the pressure gauge installed, the engine running
at full throttle, and the cutting boom LEFT/RIGHT
motion speed control valve fully closed, perform the
following checks:
Hydraulic System Pressure Checks
ACTION
GAUGE READING
Fully swing cutting
wheel to RIGHT
1500 to 1800 PSI
Fully swing cutting
wheel to LEFT
1500 to 1800 PSI
Fully extend cutting
wheel OUT
1500 to 1800 PSI
Fully retract cutting
wheel IN
1500 to 1800 PSI
Fully depress
cutting wheel
DOWN
1500 to 1800 PSI
Fully raise cutting
wheel UP
1500 to 1800 PSI
These checks are an aid to verifying the integrity of the
hydraulic cylinder seals, and the control valves. If
all
of the checks result in lower than proper gauge
readings, the control valve bank integral pressure
relief valve may be out of adjustment or dirty.
