Tools Required:

• Open-end adjustable wrench or a 7/16” socket

• Needle-nose pliers

• #2 Phillips screwdriver

Step 10: Set the crossbar of the retainer clip (25) under the two hooks on the clip bracket

as shown in Figure 4.

Step 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.

Step 12: Insert the bolt (17) through the light baffle socket casting (2). See Figure 5.

Step 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).

Step 14: Place the socket assembly (9) into the light baffle socket casting (2). Be sure it is

well seated.

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:

Note:

If the spring does not seat correctly, coax it into place with a screwdriver or needle­nose pliers.

Step 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.

Step 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).

Step 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).

Install the wave washer with the upward curve toward the hex nut.

Step 19: Insert the knurled head screw (11) through the housing socket casting (1) as

shown in Figure 7.

Note:

Use pliers to straighten the Southco retaining ring (12) if it bends when you install
it on the bolt.

Step 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.

CAUTION:

Step 23: Install the top half of the cable clamp (15) and secure it with the two screws (16).

Note:

Step 24: Using the four screws (24), attach the handle (23) to the lamp socket assembly.

You must follow the wire routing diagram to ensure that the socket leads do not
interfere with the lamp focus mechanism.

Tighten the screws alternately to ensure a solid connection.

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.

Removing reflector

Tools Required:

WARNING:

• Minimally padded work surface (cardboard, carpet, or rubber mat recommended)

This procedure may crack or break the reflector. Always wear gloves, safety
glasses, and a dust mask when performing this procedure.

Step 1: Place the reflector housing face down on your work surface so that the concave

reflector surface points downward.

at roughly a 90° angle. Tighten the clutch.

Step 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.

Step 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

Note:

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.

Step 1: Place the reflector housing casting (1) on a flat work surface with the large

opening facing up.

Step 2: Install the reflector support spring (5) in the circular opening at the base of the

casting.

Step 3: Insert the reflector (6) at an angle, under any three adjacent legs of the reflector's

clips.

Step 4: Gently press down on the opposite side of the reflector until it snaps into place

under the remaining clips.

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.

Cleaning reflector

WARNING:

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.

8 Source Four Zoom Assembly Guide

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

WARNING:

Step 1: See Figure 10. Stand the top and bottom front barrel castings (1 and 2) upright

Note:

Step 2: Slide the bottom divider plate (4) into its place in the bottom casting (2). The

The top front barrel casting (1) contains the iris slot.

dimples on the divider plate must point down.

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.

Divider plate edges are sharp. Handle with caution.

of dimpled divider plate (4) handle facing outward, up and down. (See Figure 11).

Note:

Note:

Note:

Install shutter blades with the rounded side facing up toward the front of the
casting.

Step 4: Place the middle gate plate (5) on top of the shutter blade.

Step 5: Place another shutter blade (3) on top of the divider plate and then place the

other divider plate on top.

Step 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.

Step 7: Place the top divider plate (6) on top of the two shutter blades.

Make sure no shutter assembly components are under the pattern holder guides.

Step 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).

Step 9: Connect the halves of the gate assembly using two PHMS screws (8). Hand

tighten only (25 inch pounds).

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.

10 Source Four Zoom Assembly Guide

Step 10: Turn the front barrel assembly over so that the narrower end is on your work

surface.

Step 11: Install the four shutter springs (7) between the four dimples in the shutter plate

and the tabs in the lip of the casting.

Note:

Install the springs at the joints in the castings on either of the tabs at the joint.

Step 12: Place iris slot cover (9) over the iris slot. Use two screws (10) to secure the cover.
