When removing the bumpers, start at either the
front or rear of the kart. The front has a separate
bumper covering the outside of the side bumpers;
the rear has a separate part inside the side
bumpers. Hold the socket head from the outside
and undo the nut, making sure to catch the outer
d-rubber plate after removing the bolt. When the
front and rear sections are unbolted and the front
and rear bumpers are removed, undo the bolts
holding the bumper sides, working from one side
to the other. Carefully support the bumper as it is
being unbolted to prevent dropping it on yourself
or someone else. Note that any sections that have
overlapping bumpers have longer hardware.
NOTE:
Check the rail daily for any cracks; damaged
rails must be replaced. Replace any damaged
hardware; because the karts regularly bump into
each other, it is common for the hardware to get
damaged. Replace any hardware as necessary.
Bent D-rubber plates can be straightened and
reused, as long as the nut cannot pull through the
hole in the plate. Inspect D-rubber for cracks and
damage; replace as necessary.
To install the bumper, hold up the front section
of the side bumper (curve goes towards front of
kart) and match the
fi
rst one in the middle with
the
fi
rst D-rubber on the side of the kart. Put the
bolt through the bumper and D-rubber, then add
the D-rubber plate, followed by the nut. Working
towards the back, install the rest of the mounting
hardware
fi
nger tight. Repeat on both sides. Next,
either install the front or rear bumper. Start from
one side of the kart and work across. Use a punch
through the mounting holes to hold up and help
align the bumper with the corresponding holes
as you install the mounting hardware. Once all
hardware is installed, it is okay to begin tightening
the bolts. Do not over-tighten hardware. You want
the D-rubber to just start to bulge. Over-tightening
could cause the D-rubber to split. Note that
anywhere bumpers overlap each other, they take
longer mounting bolts.
NOTE:
Make sure proper-length bolts are used.
