E) Installation instructions
The brake lining must contact the brake drum over its full surface.
The corners of the brake lining must not be broken and the lining
must not be cracked at the rivets.
Required riveting force: 25,000 N
Read off the required working pressure on the setting plate of the
rivetter and set the pressure at the pressure gauge.
Observe the rivetting sequence 1 - 8 for each brake lining half.
Brake drum
Brake drum diameter.
Permissible wear limits, see table in chapter “Maintenance instruc-
tions”.
Brake drum cleaning:
The brake drum may only be cleaned using a dry cleaning material.
Liquid cleansers, high-pressure cleaners or machine cleaning are not
permitted. With this type of cleaning there is a danger of cleansing
fluid entering the wheel bearing with a consequent failure of the
wheel bearing lubrication.
Inspecting the brake drum
Removing and installing the brake drum
Inspect the brake surface of the brake drum closely for further
serviceability.
Brake drums with fine hairline cracks in the contact surface can con-
tinue to be used. If the contact surfaces of the brake drums exhibit
deep scoring, the drums must be turned down. If cracks are still
visible after turning down, replace the brake drums.
Measure the brake drum diameter and turn down to the next repair
stage, if necessary. When the maximum permissible brake drum inside
diameter is reached, the brake drums must be replaced.
Permissible wear limits, see table in chapter “Maintenance instruc-
tions”.
