Reflector

TM 11-2323

(14) Make sure that the retaining frame is firmly seated in the

projection stage and that it is centered between the four

holes used in mounting the plate glass cover.

(15) Turn the projection stage over.

(16) Reinstall the mounting clips, screws, and lockwashers (re-

moved in (3) above); loosely attach the assembled parts

with their associated nuts.

(17) Gently insert the plate glass cover under the four loose

mounting clips.

(18) Being careful not to crack or chip the plate glass cover, hold

the nuts under the projection stage with the fingers of we

hand and tighten each of the screws in the mounting clips

with a screwdriver.

(19) Place the projection stage on the housing; align the holes

on the rear of the projection stage with the holes on the rear

of the housing.

(20) Insert the projection-stage retaining screws through the

holes in the projection stage until they engage the threaded

bushings on the housing.

(21) Handtighten the projection-stage retaining screws to hold

the projection stage firmly in place.

c. Reflector. Open the rear door of the projector (fig. 7.1). Re-

move the upper left retaining screw from the reflector mounting plate.

Carefully hold the reflector with one hand and unscrew the lower

right retaining screw. Lift the reflector mounting plate out of the

housing. The reflector is not removable from the reflector mounting

plate because the reflector retaining clips are riveted to the reflector

mounting plate. To reassemble the reflector mounting plate, perfom

the above procedure in reverse order.

Note. Whenever the Reflector mounting plate has been removed and rein-

stalled, the reflector must be realinged (par. 59c ) .

d. Glass Condenser (fig. 32.2).

(1) Raise the projection stage all the way.

(2) Support the glass condenser lens with one hand and, with the

other hand, use a screwdriver to remove the four screws on

the retaining plate.

(3) Gently lift out the glass condenser lens and the retaining

plate.

Note. The glass condenser lens has a frosted spot in the center of the

convex side to promote better light distribution.

(4) Carefully separate the glass condenser lens from the retaining

plate.
