7.2 OIL LEVEL CHECK AND TOP-UP
The oil level check must be performed periodically every 2000 operating hours,
after the onset of any start-up abnormalities or in consequence of overheating
of the hydromechanic coupling and if an oil leakage from the hydromechanic
coupling is detected. To carry out this check, please follow the described pro-
cedure:
CAUTION
Before transmission oil replacement, observe the following steps:
A- stop the motor and wait for the rotation components to stop,
B- cut out power supply and apply a safety padlock,
C- signal the operation under way,
D- wait for the cooling, if needed (max 40°C).
7.2.1
Open the accident-prevention guard of the operating area to access the coupling.
7.2.2 HORIZONTALLY MOUNTED COUPLINGS
Check the oil level in the coupling (see identification plate and TECHNICAL
DATA SHEET OF THE COUPLING).
7.2.2a
Manually turn the coupling until the oil screw plug reaches the angle inclination
determined through the pre-established calibration.
NOTE
In case the couplings are equipped with plug and level indicator, it is
sufficient to position the coupling in the pre-established filling position and check
the oil level.
7.2.2b
Remove the plug or the device mounted in the oil filling hole and check the
oil level; as an alternative, it is necessary to make up the oil as described in
section 6.3 FILLING AND CALIBRATION OF HORIZONTALLY MOUNTED
COUPLINGS.
7.2.3 VERTICALLY MOUNTED COUPLINGS
The couplings designed for vertical installation (C manufacture) are not equipped
with level check points; therefore this control must be carried out depleting and
filling the coupling again according to the final calibration values as pointed out
in the TECHNICAL DATA SHEET OF THE COUPLING.
7.2.3 a
To empty and store the coupling, observe what set out in section 6.6. TRANS-
MISSION OIL REPLACEMENT IN VERTICALLY MOUNTED COUPLING.
The level check of the hydromechanic coupling has thus ended
