7.1.2 Adjusting the Air Gap

Use a feeler gauge to test the air gap at several points around the brake's

circumference.

Remove the armature and hub (if included) by reversing the installation steps for the

armature assembly.

Adjust the air gap to width X.

When adjustment is complete, fasten the armature assembly and hub (if included) to

the shaft or mounting surface.

Use a feeler gauge to test the air gap to ensure the adjustment was performed

correctly. Repeat steps 2-4 if the air gap is not at width X.

NOTICE

The COMBINORM brake should be cleaned prior to installation as well as periodically

during regular maintenance. The brake should be disassembled prior to cleaning. Clean

the armature and friction lining with an alcohol based brake cleaner.

If the air gap is larger than X

For flange-mounted brakes with hubs, adjust the hub position on the shaft until

the air gap is at width X.

For flange-mounted brakes without hubs, adjust customer provided hub until the

air gap is at width X. Adjusting shim washers between the armature (6) and the

mounting surface (7) can be used until the air gap is at width X (see Fig 9).

 Shaft-mounted brakes are shipped with a factory set air gap which

cannot be adjusted. Shaft-mounted brakes require replacement if the

air gap grows beyond the maximum X

 The friction surfaces must be thoroughly cleaned and dried prior to

returning the brake to operation.

 Any remaining cleaning liquid or other foreign contaminants on the

friction surface may result in a loss of braking torque.

the air gap needs to be adjusted.
