TESTING AND ADJUSTMENTS
METHODS FOR TESTING FOR LEAKAGES
INSIDE THE SWIVEL JOINT
3 - Disconnect from the relative actuators the tubes
that correspond to the lines adjacent to the one
being checked. Plug the disconnected tubes to
prevent entry of impurities.
H
To identify the lines adjacent to the line being
checked, please refer to Tables
A
and
B
.
4 - Wait a few minutes to give the oil in the tubes time
to drain out.
4. Preparation for testing the blade
1 - Release all residual hydraulic pressures.
(See «ELIMINATION OF THE RESIDUAL PRES-
SURES FROM THE CIRCUITS»).
2 - Disconnect from the blade cylinder (3) the tube (4)
corresponding to the line to be checked and seal
it. Also plug the holes in the actuators to prevent
entry of impurities.
3 - Disconnect from the relative actuators the tubes
that correspond to the lines adjacent to the one
being checked. Plug the disconnected tubes to
prevent entry of impurities.
H
To identify the lines adjacent to the line being
tested, please refer to Tables
A
and
B
.
4 - Wait a few minutes to give the oil in the tubes time
to drain out.
5. Checking the leaktightness
1 - Start the motor and bring it up to the testing speed
for each group of components.
2 - Pressurise the line to be tested.
3 - After 30 seconds, then for the next full minute
check to see if there are any leakages.
H
If oil leaks out of one of the two tubes of the
actuators (adjacent lines), it means that there
is a leakage of the intermediate gasket bet-
ween the high pressure line and the adjacent
line.
