ÈDOOR SEAL REPLACEMENT ON
RAPID LOAD MODELS
ÊDoor Seal Replacement
The seal components referred to herein are contained in kits K28 0005R (for 60" machines) or K36 0003R (for
72" machines).
1. Remove old seal from the door cavity and carefully pull air tubing out of inner door so as not to cut tubing.
2. Remove as much as possible of the old adhesive from the rubber filler strip inside door cavity.
3. Carefully remove old seal from the air tubing fittings and attach new seal.
4. Carefully stretch new seal around door and into cavity. Because the new seal is fabric reinforced it is slightly
narrower than the old style rubber seal; the wall is thinner and it does not stretch as easily. It will therefore
feel much tighter than the all rubber seal when stretching it over the edge of the door.
5. After new seal is fitted and aligned into the door cavity, close both doors and inflate. Check to see that seals
contact each other along the seam between the doors and that the seal contacts the shell front all around. To
check this, attempt to slide a piece of paper between these surfaces.
6. If the seal does not contact the shell at locations A or D (see FIGURE 1), open the doors and stretch the seal
toward these points.
7. If seals do not contact each other or the shell front in other areas, install rubber shims (part number 02
175267) between seal and filler strip as required to bring the seal further out from the door. Use adhesive
(part number 20C015A) to attach shims to filler strip.
8. If seals do not contact each other at locations A and B, (see FIGURE 1), then at these points, glue tapered
patches (part number 02 175134), as required, to the outside of seal (using adhesive 20C080C) to add thick-
ness.
9. After seal has been completely fitted, roll seal up on one side, and with a small brush, paint adhesive (part
number 20C015A) on filler strip to hold seal in place.

ÊDoor Seal—Preventive Maintenance
ËCheck Door Alignment About the Shell Opening—Each door must be centered in its respective
shell front opening. If the doors are not centered, the inflatable door seals will drag on the sealing edge of the shell
front as the doors are opened and closed. The doors can be moved in any direction for centering by loosening the
1/2" hex cap nuts which hold the door assembly to the hinge cross brace as shown below.
Location A—Seals must
contact each other and
shell front.
Location C—Seals must
not drag against shell
when door opens.
Location D—Seal must
contact shell front.
Location B—Seals must
contact each other and
shell front.
