3.
Remove the linings (Z50353/Z50355/Z50354) from the brake by pulling the lining base
outward; remember that considerable force will be necessary to overcome the resistance
due to the attraction of the magnet (C62333) incorporated in the thruster (D71313).
4.
Remove any oil or grease from the surface of the disc using a non-pollutant detergent
product.
5.
If the linings are contaminated, even if only on the surface, it is a good idea to clean them
using fine emery paper. If the contamination is deep replace the linings with new ones.
6.
Put back the lining pads re-attaching them to the magnet (C62333)
incorporated in the
piston (D71313).
7.
Align the holes of the brake body (E80886) and the backing plate in which the guide pins
will be inserted. Re-insert the guide pins (C62328) in their housings and anchor the plates
(C62329) to the body using the screws (C61431) previously removed.
(If the brake has been removed from the machine skip this point and follow the
instructions in section 9.3.7)
9.3.
Changing the sealing rings
1.
Cut off the hydraulic oil pressure, disconnect the power line and remove the brake from the
machine.
2.
Remove the linings (Z50353/Z50355/Z50354) from the brake by pulling the lining base
outward; remember that considerable force will be necessary to overcome the resistance
due to the attraction of the magnet (C62333) incorporated in the thruster (D71313).
3.
Remove the anchoring screws (C61458), the washers (C61343) and cover (D71312). Insert an
M16 screw in the relative threaded hole of the piston (D71313) and remove the piston by
pulling on the screw.
4.
Remove the gaskets and the damaged sealing rings and replace them. It is advisable to
replace the complete kit supplied by COREMO OCMEA, consisting of 2 g 2 scraper
rings + 2 guide rings + 2 o-rings, to avoid further possible downtime.
5.
Put back the piston (D71313) with the utmost care and attention then put back the cover
(D71312) on the brake body (E80886) using the screws (C61458) and the washers (C61343)
following a diagonal sequence. The tightening torque of the M16 class 12.9 screws (C61458)
is 341 Nm.
6.
Put back the lining pads re-attaching them to the magnet (C62333)
incorporated in the
piston (D71313).
7.
Put the brake back on the machine and reconnect the power pipe; power up the brake and
bleed air from the circuit as described in point 2 of section 7.
9.4.
Changing the springs
1.
Cut off the hydraulic oil pressure, disconnect the power line and remove the brake from the
machine.
