Routine Maintenance
154 CLCH-SVX07K-EN
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.
To minimize air that bypasses the wheel the perimeter
seals should be adjusted such that air gaps are not visible
around the wheel. Do not over compress the seal against
the perimeter as this may cause the wheel not to turn or
overload the motor. To minimize air the leaks from one
side to the next the diameter seals should be adjusted to
come in full contact with the wheel face.
