Expansion Tank; Brake Lubrication - brevini ED2090MR20FL350B3 Manual De Instalación Y Mantenimiento

Checking the oil with non-forced lubrication
If the gear unit is fitted horizontally, the oil level should be at the
centre if proper lubrication is to be guaranteed (see fig. 7).
Fig. 7
For applications with a very low output rotation speed (n 2 ≤ 5
rpm) it is advisable to fix the level at a value higher than 50-100
mm (see fig. 8).
To check the oil level, simply use a transparent tube, positioning
it as shown in fig. 8.
If the output speed is extremely low (n 2 ≤ 1 rpm), or if long gear
unit downtimes are foreseen, it is advisable to fill the entire
casing. In this case, a special "expansion tank" must be fitted.
Fig. 8
If a gauge is fitted for checking the level visually (or by means of
an electrical signal), this must be fitted as shown in the diagram
in fig. 9. Position the breather cap above the level indicator,
using a tube of the right length, connecting the upper (empty)
part of the gear unit to just below the breather. This will prevent
oil from spilling out.

Filing and level
- The gear units are equipped with oil level, breather, filer
and drain plugs and their position changes according to the
installation configuration.
- Check the exact position of the plugs using the diagrams on
paragraph 2.2 "configuration".
- Unscrew the level-filler plugs, put oil into the Gear unit and
when this oil flows out of the level hole, replace the plugs.
- In the RPR or MDU series, one of the support bearings must be
lubricated with grease, using the grease gun located above the
gear unit attachment flange, and using a generic type of grease
with the features indicated in paragraph 7.3.

- The lubricant oil used in the gear unit-coupler assembly with
active clutch safety system is the same as the oil used in the
clutch pump.
- Turn the gear unit a few times to eliminate any air pockets and
then check the various levels.

7.2 Expansion tank

ATTENTION: make sure the expansion tank is installed higher
than the top part of the gear unit.
For applications with an expansion tank, do the following: (see
figure 3).
- Remove the plug "A"
- To enhance gear unit ventilation
(only during the filling phase) it is also
possible to remove one of the top of
the gear unit.
- As the oil rises to the top of the open
plug in the top part of the gear unit,
replace the plug.
- Continue filling until the oil reaches
the min. visual level plug on the tank
which should not to be exceeded to
provide space for the volume of the
hot oil to expand.
- Replace the plug.
- With the gear unit running under
steady-state thermal conditions, and
the oil at its maximum expansion
temperature, never exceed the max.
level.
- Run the gear unit for a few minutes
to eliminate any air pockets, then check the various levels.

7.3 Brake lubrication

Multi-disk brake
- The Brevini multi-disk brakes are supplied without oil.
- The user must select the lubricant features.
- To lubricate the multi-disk brake unit, BREVINI POWER
TRANSMISSION S.p.A. recommends using mineral oils with
