The procedures contained herein are not exclusive. General Coach America, Inc. cannot

1. Remove the curbside section of aluminum angle from the step into the rear floor section.
Save it for use later in this procedure.

2. Use a knife to cut the rubber that was previously capped by the aluminum angle.
Remove this length of rubber. Save it for use later in this procedure.

3. Place the metal frame in position to assess its sizing. Due to slight variation between
buses, it may be necessary to use a saw to cut the frame to size. First, determine if it
needs to be trimmed front-to-back. The front face of the frame must not go past the front
face of the modesty panel. Trim the short leg if this is the case.

Front face must not go
past modesty panel

Do not go past this
modesty panel

4. For side-to-side sizing, the frame must be long enough so its short leg is nearly flush with
the center step tread. Trim the long leg as shown in step 5 to adjust this length.

with center step tread

5. Because the curbside edge of the frame must interface with coved flooring, any trims
made to alter its length must be cut to work with the cove.

Cut must be similar to red
line to meet coved floor.
6. With the frame set in place, mark its top surface on the metal of the original step-up
section. Take the 1.5”x1” aluminum angle and cut it to length so that it fits between the
new step frame and the wall.

Fit this angle between
wall and step frame.

Fit this angle between
wall and step frame.

7. Use the included pan-headed screws to mount the aluminum angle so that its top surface
is exactly even with the top surface of the new step frame. The 1” leg should be pointing
forward, and the 1.5” leg pointing down.

Make top surface of angle
flush with new step frame.

8. Secure the frame flat to the floor using pan-headed screws. Center the screws on the
accessible flange.

9. Due to slight variations in manufacturing, the rear floor section of the bus may be at
slightly different heights. Therefore, a sheet of plywood and luan are provided to provide
the subfloor for use atop the step frame. To make the subfloor of the step level with the
subfloor of the rear floor section (keeping in mind rubber will be added later), it may be
necessary to use luan only, plywood only, or a combination of each. Luan scraps are also
useful for making shims for fine tuning. Once the subfloor stack-up is selected, secure it
to the step frame using the counter-sunk screws included.
Use this screw if the stack-up
does not include plywood.

10. Next, lay the rubber step tread on top of the new step and original rear floor section.
Mark on the step tread where to make cuts for (a) the coved floor and (b) the seat track.
Remove the step tread and use a saw to make the cuts. Make the cut for the coved floor
at least 1.5” into the tread to ensure the tread will not be sitting on a curve.

(a) Coved floor cut-out,
1.5” inward to sit flat

(b) Seat track cut-out,

11. Lay the newly trimmed rubber on the step again. Mark the rubber on the rear floor
section that needs to be cut away for the step tread to sit flat at the rear. Place the tread
aside, and use a knife to cut out the section of rubber and save it for later use.

This section of rubber on rear floor
is cut out to let new tread sit flat.

12. Using the scraps of rubber created in steps 2 and 11, trim them to fit the front and side of
the new step assembly. Use 3M-90 spray adhesive to adhere the rubber to the step.
Follow the instructions on the spray can for proper results.

13. Place the rubber tread on the step assembly for the final time, ensuring it sits tight and all
gaps are to a minimum. Secure the tread to the step assembly using pan-headed screws.
Place the screws in the valleys of the treads to minimize their protrusion. Cut a section of
the aluminum angle from the piece saved in step 1, and use it to trim out the short leg of
the step assembly. Secure it with pan-headed screws.

Screw is in
valley.

14. Seal all gaps and intersections with gray sealant. The procedure is complete.
