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.
