Oil Change; Unscheduled Maintenance; Maintenance Of Auxiliaries (Brakes - Clutches- Etc.); Procedure To Replace Disks Or Seals For Multi Disc Brake - brevini ED2090MR20FL350B3 Manual De Instalación Y Mantenimiento

- Subsequent oil changes will be made every 200-2500 hours of
operation or, in any case, each year.
- Do not mix different types of oil.
- Periodically check the levels (about once a month) ant top up
if necessary.
ATTENTION: when checking the oil levels in gear units equipped
with a multi-disk brake or hydraulic motor or both, if the levels
have risen, this means that oil is penetrating either from the
brake seals or from the motor rotary seal. Contract the "Brevini
Service Department".
- For each unit it is recommended to keep a chart that will be
duly filled out and updated each time maintenance in performed.

9.2 Oil Change

- Use the diagrams on paragraph 2.2 "configuration" to identify
the oil plug according to the gear unit configuration and always
paragraph 2.2 for the multi-disk brake configuration.
Unscrew the drain plug and the filler plug to help drain the oil
from the gear unit. Once the oil has been emptied, replace the
drain plug. If the gear unit is equipped with a multi-disk brake,
repeat the same operation with the multi-disk brake.
- In the MDU series, starting with size "550", a pipe is supplied
to empty the oil in the gear unit, therefore it must be emptied
using a suction pump, removing the plug from the emptying pipe
located on the flange attaching the gear unit and fitting to it.
- Wash the interior of the gear unit with a suitable cleaning
liquid that is recommended by the lubricant manufacturer. If the
gear unit is equipped with a multi-disk brake, repeat the same
operation with the multi-disk brake, as follows:
Put liquid into the gear unit and the multi-disk brake (if any), hen
replace the filter plugs; run the device for a few minutes at a high
speed, then remove the cleaning liquid again from the gear unit
and the multi-disk brake. (if any).
- See paragraph 7 Lubrication for filling instructions.

9.3 Unscheduled maintenance

BREVINI POWER TRANSMISSION S.p.A. prohibits the
gear unit to be opened to carry out any operation that is not
included in routine maintenance procedures. BREVINI POWER
TRANSMISSION S.p.A. do not undertake any liability for all
those operations out of routine maintenance which may have
caused damages to people or things. When the need arises,
contact the nearest Brevini Service Centres as listed on page
117.

10. MAINTENANCE OF AUXILIARIES (BRAKES - CLUTCHES- ETC.):

10.1 Procedure to replace disks or seals for multi disk brakes
"BREVINI POWER TRANSMISSION S.p.A." prohibits this
operation to be performed on its units, therefore if braking action
becomes inefficient contact the nearest Brevini Service Centres
as listed on page 117.
10.2 Procedure to replace pads
for disk brakes
- Use a screwdriver or similar
tool to pry between the disk and
the pad to make the position of
the brake clamp retract up to the
start of the stroke. Carry out this
operation first on one side and
then on the other for both pistons.
- Use a pin remover and hammer
to remove one of the two pins "A"
from its seat (see fig. 4), remove
the two springs "B", then remove
the other pin.
- With a mechanical clamp pull
Fig. n. 4
To force
A
B
out the two worn pads, use compressed air to clean away any
dust from the pad seats in the brake clamp, then insert the new
pads.
- Mount one of the pins "A" in its seat, place the two springs "B"
in their position, put them under tension, them mount the other
pin in its seat.
- Activate the brake a few times to re-position the pistons of the
brake clamp with the new pads.
- Brake a few times to check if bleeding is required.
10.3 Maint. proc. for hydr. power pack on gear unit-coupler
assembly with active clutch safety system
- The power pack "B" has an inspectable 100 µ bronze filter,
upstream of the
pressure relief valve.
- With each routine
maintenance job (oil
change) on the gear
unit-coupler assembly
you are advised
A
either to change the
power pack filter, by
unscrewing the cap "A",
or at least to regenerate
it by washing thoroughly
with solvent and blow-
cleaning inside the filter
with air.
- If the power pack
"B" has to be replaced:
empty the lubricant oil out of the assembly, cut off the current to
the solenoid valve, disconnect the oil delivery tube, unscrew and
remove the 4 bolts pos. "C" and then withdraw the power pack
for replacement.
- To reassemble, go through the above steps in reverse order;
see par. 6.3 for resetting the power pack.

11. SCRAP DISPOSAL:

11.1 Machine demolition
If the machine must be scrapped, it, should become non-
operational:
- Disassemble the various parts.
- Disconnect any motor unit.
But first after having completely emptied all the oil from gear unit.
11.2 Ecology information
The disposal of gear unit packaging materials, replaced parts,
components or the gear unit and lubricants must comply with
environmental restrictions, without polluting the soil, water or air.
The party receiving the materials is responsible for carrying out
the operation in conformity with the current standards in force in
the country in which the machine is used.
Instructions for suitable waste treatment
- Iron, aluminium, copper materials: these are recyclable
materials which must be sent a to a special authorized collection
center.
- Plastic and rubber materials: these materials must be delivered
to a dump or to special recycling centers.
- Used oils: deliver to a special C.Di.R.A. (in Italy the Consorzio
Obbligatorio Oli Esausti).
