Disassembly

1.

Start the disassembly by slightly loosening the screws (40). Not more than
one turn each. Continue with one turn of each screw around the cover until
the preload of the belleville springs (315)(cup springs) is zero. After that the
screws can be removed and the brake cover (314) lifted off.

2.

The brake piston (313) can be removed by installing 3 screws (M8) and be
lifted off by using the screws.

3.

Inner and outer discs (318, 320) can be removed and the spacer (308) in place
can be removed.

4.

Loosen the screws (43), and take off the seal retainer (25).

Assembly

1.

Oil the screws (43) and assemble with washers, torque 136 Nm (100 lb·ft).

2.

Place the correct spacer (3xx) inside the brake housing (305). See

3.

Mount the discs, start with an outer steel disc and alternate inner friction discs
with outer steel discs until the correct number of discs are reached for the
brake size. See

. Always end with an outer steel disc.

4.

Grease the piston seal and guide strip with multi-purpose grease without solid
additives. Mount the brake piston (313) in the brake housing (305), tap it in
place with a plastic hammer. Remove one of the plugs in B1-B2 connection to
evacuate the air during assembly.
