Door Assembly (cont).
If there is resistance to the withdrawal at all of the test points, sufficient seal
pressure exists on the silicone weather gasket, and adjustments are not neces-
Adjust. (Figure 3-18) Adjustment to increase the seal pressure on the silicone
weather gasket can be made on the hinged side of the door and on the roller latch side of the
door, as described in the following paragraphs:
Weather Gasket Pressure Adjustment (Hinge Side). To increase the weather
gasket pressure on the hinged side of the door, proceed as follows:
Open the door and remove and retain three bolts (1), flat washers (2),
and self-locking nuts (3) attaching the hinge to the door.
Insert shim (4), approximately 0.032 inches thick and matching the
hinge body in size, between the hinge body and the door.
Secure the hinge body to the door using three bolts (1), flat washers (2),
and self-locking nuts (3).
Repeat the test procedures of paragraph 3-17.b. and repeat this
adjustment procedure as necessary.
Weather Gasket Pressure Adjustment (Latch Side). To increase the weather
gasket pressure on the roller latch side of the door, proceed as follows:
Open the door and remove and retain the hex head screws (5 and 6) and
lock washers (7) from the top and bottom hole attaching the keeper (8)
to the wall, and remove keeper and shim (9). Remove detent pin (10)
from center keeper.
If more than one shim is required, additional shims may be added,
up to a maximum thickness of 0.096 inches.
If the seals are not tight after the maximum allowable thickness is
obtained, the seal should be replaced as the material has likely
Add a 0.032 inch shim between the keeper (8) and the shelter.
Repeat the seal pressure test of paragraph 3-17.b. If the seal pressure
remains insufficient, add another 0.032 inch shim.
Repeat this process until sufficient seal pressure is developed or until
the maximum allowable thickness is obtained.
