CDQ Seal Adjustment
Neoprene brush seals are located on both sides of the
cassette around the wheel perimeter and the center
diameter posts. The seals are designed to come in contact
with the wheel and require no maintenance other than
adjustment. The seals consist of a metal and neoprene clip
that grips to the metal posts or panels. These clips can be
manually adjusted.
