Warner Electric Gen 2 Ceramic Faced Clutch_Brake UniModule UM-50C, UM-180C - Manual (Page 7)

on the spline. If this occurs, a slight pry on the
armature usually gets it back into position.
The ceramic faced friction surfaces of these
UniModules are pre-burnished and performance
tested at the factory to ensure consistent “out of
box” performance. Therefore, no “wearing in,” or
burnishing, is required. Full rated performance
should be achieved after running for a few cycles,
usually fewer than 50.
Repair and Replacement
Ceramic UniModules will provide reliable and
consistent performance throughout the
exceptionally long life of the friction facings.
Their long life results from the exceptional wear
resistance of the ceramic material. The low wear
rate also results in a longer burnish time to “mate”
the friction surfaces. Alignment of the friction
surfaces of both clutch and brake are also very
critical. Therefore, these units are not field
serviceable. All repair work must be done by
the Factory where alignment and burnishing
can be closely monitored.
Please note that units with damage to the
non-wearing components, such as housings and
shafts, are not repairable. The factory will evaluate
returns and determine if they can be repaired.
The optional cover kit normally
available for the standard UniModule is not
recommended for use with the Ceramic
UniModule. The unauthorized use of this kit
with the Ceramic UniModule may void the
Warranty.
