TRACK BELT RECONDITIONING - CONTINUED
5 . Using a sanding block with 50 Grit sandpaper,
sand both wear surfaces on the outside edges of
each belt . The purpose is to roughen the surface
of the belt just enough to remove the shiny spots
caused by normal wear . Do not over sand the belts .
WARNING
Do not sand the track teeth . Deformation of the teeth can
cause unpredictable chair performance resulting in injury to the
operators and/or passenger .
6 . Remove all sanding debris from the belts and the track
frame .
7 . Turn both belts back over so the large teeth are on the
outside .
8 . Replace the hex head bolt, hex nut, two washers,
spacer and wheel on both sides of the track frame .
9 . Use two 7/16" wrenches to apply the desired tension to
each belt and tighten securely .
Note: To check the tension, pull up on the center of the belt
until it is taut . The gap between the belt and the track frame
should measure between 3/8" and 1" as shown in Figure 48 .
10 . Spin the belts to verify they roll freely .
