Assemble lamp socket
Tools Required:
• Open-end adjustable wrench or a 7/16” socket
• Needle-nose pliers
• #2 Phillips screwdriver
10: Set the crossbar of the retainer clip (25) under the two hooks on the clip bracket as shown in
Figure 4 .
11: Place the Tinnerman clip (18) over the retainer clip crossbar between the two hooks and press it
down firmly until it snaps into place.
12: Insert the bolt (17) through the light baffle socket casting (2). See
Figure 5 .
13: Install the green ground wire assemblies (19 and 22) on the bolt (17) with the prongs on the
crimped connectors toward the casting. Run both wires through the indent in the lip around the
bolt hole. Secure with nut (10) and tighten securely (60 inch pounds).
14: Place the socket assembly (9) into the light baffle socket casting (2). Be sure it is well seated.
15: Install the lamp retainer spring (7). The lamp retainer spring secures the socket. Insert the spring
one end at a time, making sure the rectangular slot in each side of the spring seats on the
corresponding tab in the casting.
Note:
If the spring does not seat correctly, coax it into place with a screwdriver or needle-
nose pliers.

16: Install the bushing cup (5) into the housing socket casting (1) as shown in Figure 6 . The cup
should slide smoothly up and down, but not side to side.
17: Insert the threaded end of the index hub (6) through the holes in the bushing cup and the back
of the housing socket casting (1).
18: Slide the X-Y knob (3) over the exposed index hub bolt (6), then insert the wave washer (14) on
the bolt and secure with the 9/16 hex nut (13). Hand tighten the X-Y knob (3).
19: Insert the knurled head screw (11) through the housing socket casting (1) as shown in
Figure 7 .
20: Install the shorter green ground wire (22) onto the screw. The prongs on the crimped connector
should be toward the casting.
21: Install the ground spring (21) onto the screw and secure it with the Southco flat retaining ring
(12). Install the Southco ring with its prongs away from the casting.
22: Lay the leads in the bottom half of the cable clamp (located in the housing socket casting [1]),
making sure that the fiberglass sleeving extends slightly past the screw holes in the housing
socket casting. Install new sleeving if necessary. Then, route the wires as shown in
Figure 8 .
23: Install the top half of the cable clamp (15) and secure it with the two screws (16). Tighten the
screws alternately to ensure a solid connection.
Note:
Install the wave washer with the upward curve toward the hex nut.
Note:
Use pliers to straighten the Southco retaining ring (12) if it bends when you install it
on the bolt.
CAUTION:
You must follow the wire routing diagram to ensure that the socket leads do
not interfere with the lamp focus mechanism.

24: Using the four screws (24), attach the handle (23) to the lamp socket assembly. See Figure 3 .
25: Place the compression spring (8) on the protrusion on the inside of the index hub (6).
26: Insert bolt (17) through spring (8) and through the index hub (6) of the housing socket (1), joining
the two castings. Make sure wires are not pinched between the two pieces.
27: Before proceeding, check again to make sure the wires are still positioned as indicated in
Figure
6
. . Adjust if necessary.
28: Press the two castings together firmly so the bottom of the light baffle (2) sits on top of the cable
clamp (15), then install the X-Y lampset (3) and Z lamp knob (4). Hand tighten the knob all the
way to the right.
Note:
To ensure that the clamp holds the cable tightly, flatten the cable, then fold over the
sleeving before you install the top half of the clamp. Make sure the top edge of the
cable clamp is even with the edge of the socket to prevent interference with lamp
focus movement. Make sure sleeving is not pinched.
CAUTION:
You must install Z knob as described above to ensure proper lamp focus
travel.

Reflector Housing Assembly 9
Reflector Housing Assembly
Removing reflector
Tools Required:
• Minimally padded work surface (cardboard, carpet, or rubber mat recommended)
1: Place the reflector housing face down on your work surface so that the concave reflector surface
points downward.
2: Loosen the clutch and rotate the yoke so that it is perpendicular to the housing at roughly a 90°
angle. Tighten the clutch.

3: Using the yoke as your handle, raise the housing assembly off of the work surface a few inches
and then firmly tap the housing on the work surface. This should force the reflector out of its
clips.
4: Carefully lift the housing to see if the reflector is released. If it is not, repeat step 3 with slightly
more force.
Installing reflector
1: Place the reflector housing casting (1) on a flat work surface with the large opening facing up.
2: Install the reflector support spring (5) in the circular opening at the base of the casting.
3: Insert the reflector (6) at an angle, under any three adjacent legs of the reflector's clips.
4: Gently press down on the opposite side of the reflector until it snaps into place under the
remaining clips
.
Cleaning reflector
Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl alcohol, distilled
water or a 50%-50% mixture of each can be used to clean the glass surface.
Note:
The following assumes all four reflector retainer clips (2) have already been riveted to
the reflector housing casting (1) and the gate bushings (3) installed on the retainer
clips. See Figure 9.
Note:
If the reflector does not snap in, turn the casting over. Gently pull on the side of the
reflector that has not snapped in until the rest of the reflector slides into place.
WARNING: Do not use ammonia-based or other harsh commercial cleaners. Clean
reflector only as directed.
Commercially available glass cleaning agents should be avoided as they may
contain ammonia, other harsh chemical detergents or abrasive agents. These
cleaners may damage the glass surface and the Anti-Reflective coatings. Do
not immerse or soak the glass in any cleaning solution.

Assemble front barrel assembly
Tools Required:
• #2 Phillips head screwdriver
1: See
Figure 10 . Stand the top and bottom front barrel castings (1 and 2) upright with the shutter
end of the castings toward the bottom.
2: Slide the bottom divider plate (4) into its place in the bottom casting (2). The dimples on the
divider plate must point down.
3: With the bottom barrel casting (2) to your left, place one shutter blade (3) on top of dimpled
divider plate (4) handle facing outward, up and down. (See
Figure 11 ).
4: Place the middle gate plate (5) on top of the shutter blade.
5: Place another shutter blade (3) on top of the divider plate and then place the other divider plate
on top.
6: Place the two shutter blades on top of the divider. Pull the blade and plate assembly slightly
forward to allow the handle to slip through the slot in the bottom casting.
7: Place the top divider plate (6) on top of the two shutter blades.
8: With both front barrel castings still standing upright, join the two halves, sliding the handle of
the top shutter blade through the slot in the top front barrel casting (1).
9: Connect the halves of the gate assembly using two PHMS screws (8). Hand tighten only (25 inch
pounds).
WARNING: During assembly, the shutter springs can pop out of place. Always wear
protective eyewear during this procedure.
Note:
The top front barrel casting (1) contains the iris slot.
Note:
The bottom divider plate (4) has four dimples punched into the surface; the top plate
(6) has none. The middle divider plates (5) are noticeably thinner-gauge metal than
the other two.
The notches on the divider plates must fit against the flanges in the casting so the
plates do not move.
WARNING: Divider plate edges are sharp. Handle with caution.
Note:
Install shutter blades with the rounded side facing up toward the front of the casting.
Note:
Make sure no shutter assembly components are under the pattern holder guides.
Note:
The tops of the two front barrel castings must be even. Adjust as necessary before
completely tightening the screws. Failure to do this could interfere with the barrel
rotation.

Front Barrel Assembly 13
10: Turn the front barrel assembly over so that the narrower end is on your work surface.
11: Install the four shutter springs (7) between the four dimples in the shutter plate and the tabs in
the lip of the casting.
12: Place iris slot cover (9) over the iris slot. Use two screws (10) to secure the cover.
Note:
Install the springs at the joints in the castings on either of the tabs at the joint.
