the gaskets to avoid further down time of the machine. Before placing the new gaskets in
their seats, lubricate with lithium soap grease, mineral oil and solid lubricants. Grease the
thruster stem too before remounting the internal thruster / plate unit.
5.
Put back the cover and secure the unit by tightening the anchor screws.
6.
Put the thruster back on the brake anchoring it with the two ring nuts. Reconnect the
flexible hose.
7.
Apply the brake a number of times to ensure that the internal thruster slides perfectly and
check for any air leaks (for pneumatic thrusters) or oil (for hydraulic thrusters).

Changing the brake shoe alignment springs
1.
Cut off pressure to the thruster.
2.
Remove the seeger C61275, then pull out the pin C61110 and remove the brake shoe
Z50263.
3.
Remove the shoe alignment spring C61968 from its seat and replace it with a new one,
positioning it as shown in Figure 2.
4.
Remount the brake shoe following the procedure in point 2 in reverse.
5.
Readjust the play between the disc and the lining as described in Chapter 9.1.
9.7.
Periodic maintenance
All inspections must be done with the machine switched off.
Although the intervals between these inspections depend on the frequency of use of the
brake, they should be done every 3 months in any case so as not to compromise all
aspects of safety.
1.
Check that the play between each lining pad and the friction disc does not exceed 1
mm. If the play is too large adjust it to the initial value as described in Chapter 9.1.
When the wear of each lining reaches 6 mm replace it as described in Chapter 9.2.
2.
Check that the surfaces of the linings and the disc are not contaminated with grease, oil
or similar substances as these prevent the brake from working effectively.
3.
Check that the anchoring screws of the brake and the brake units are correctly
tightened.
4.
Check the condition of the flexible hoses.
5.
Apply the brake a number of times to check the condition of the gaskets, the operation
of the springs and correct sliding of the stem.
