4. Repeat step 3 to remove the support side tip wipe assembly.
5. Clean and inspect the surface around the locating pins. Make sure that the tip wipe assemblies
can sit flush on the surface.
6. Inspect the flicker portion of the tip wipe assemblies. The top edge of the flicker should be
straight and must not contain excessive notching/wear.
7. Inspect the brush portion of the tip wipe assemblies. Brush bristles must not show evidence of
wear (i.e. no notches in bristle pattern) and should not contain significant bristle clumping. Frayed
bristles are acceptable as long as the top edge is even across all of the bristles.
8. Replace one or both of the tip wipe assemblies if excessive wear is present. See Table 7-2 for
information on ordering replacement assemblies.
• The components of the assembly cannot be replaced individually. The entire tip wipe assembly must
be replaced if excessive wear is present on the flicker or the brush.
