To fill and calibrate the horizontally mounted hydromechanic coupling, observe
the following steps:
6.3.1 TRANSMISSION OIL FILLING
CAUTION
Before the hydromechanic coupling is filled and/or calibrated,
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 underway,
D- Wait for cooling, if needed (max 40°C)
6.3.1a
Open the accident-prevention guard of the operating area to access the coupling.
6.3.1b
Turn the coupling until the oil screw plug is accessible on the pre-established
angular position with respect to the vertical axis (see section TABLES FOR
COUPLING FILLING).
NOTE
In plants, where the couplings outer shell cannot freely rotated to adequately
position the oil screw plug, a CL device may be installed (see section 6.2 OIL
LEVEL CHECK AND TOP-UP and 7.2.4 COUPLINGS EQUIPPED WITH CL
DEVICE).
6.3.1c
Remove the plug (or the device) to fill the coupling with oil.
6.3 FILLING AND CALIBRATION OF HORIZONTALLY MOUNTED COUPLINGS
54
P o w e r T r a n s m i s s i o n
This section shows the tables with the filling quantity (in litres) for the coupling, according to a specific
angular location of the lubricant oil screw plug with respect to the vertical axis of the hydromechanic coupling
horizontally mounted.
For different filling angles (reported on the first line above) of hydromechanic coupling size (as pointed out
on the first column left) you may read the correct angular position of the horizontally mounted coupling and
the height of the plug with respect to the lowest point of the external diameter of the coupling.
CAUTION
The hydromechanic coupling must be filled in compliance with the type of expected start-up.
Do not fill the coupling with a too small or a too large amount of fluid. DANGER OF OVERHEATING
AND BEARING SEIZURE AND DANGER OF OIL LEAKAGE DUE TO INTERNAL OVERPRESSURE
AND POSSIBLE STRUCTURAL FAILURE.
