d. Outlet Port (Front Plate) Maintenance
1 Remove the four ½-13 x 1½ inch long hex head bolts (BLT015) and the one 5/16 x 1½ long
security screw (SCR154) that attach the outlet port to the (empty) projector body.
2 Disassemble the front plate (outlet port mechanism) by first removing the set screw (SCR251)
from the outlet port cover (knob). Discard the used set screw.
3 Unscrew the two socket head cap screws (SCR160) from the pivot disk.
4 Remove and discard the two compression springs (SPR033) from the outlet port mechanism.
5 Clean all parts in solvent using a brush to dislodge all dust and dirt. Dry all components
thoroughly. Do not lubricate, leave all components completely dry.
6 Inspect the bronze rotor shaft (86037) with spring roll-pin attached to ensure the shaft is not
damaged, bent, or worn, and the spring roll-pin (PIN058) is not cracked, broken or loose in the
bronze rotor shaft. Replace the rotor shaft with spring roll-pin attached if necessary.
7 Inspect the brass slider (86035) and rotor surfaces (86032) for wear and burrs.
8 Verify the tungsten port shield (86034) is not loose within the rotor. If the port shield is loose,
replace the rotor.
9 Inspect the entire outlet port for wear and burrs especially in areas where the source guide tube
bayonet fitting engages.
10 Install new compression springs (SPR033) and re-assemble the outlet port mechanism. Apply
low strength Loctite
TM
thread lock (GLU018) to the socket head cap screw threads before
tightening.
11 Apply low strength Loctite
TM
thread lock (GLU002) to the threads of a new set screw (SCR251).
12 Install the new set screw into the outlet port cover (knob) (88033) and through the bronze shaft.
See reference drawing with part numbers in Figure 14.
e. Outlet Port Functional Safety Check
1 After reassembly of the front plate, perform the following safety function tests using a bayonet
source guide tube fitting.
2 Pull the outlet port cover and rotate clockwise 90 degrees. Movement should be smooth and
limited to a clockwise 90 degree turn.
3 Insert a bayonet fitting into the outlet port and rotate 90 degrees in a counter-clockwise direction.
Insertion and rotation of the bayonet fitting should be smooth and without snags.
4 Rotate the outlet port cover from a 3 o’clock position to a 5 o’clock position. This operation
moves the rotor from the port shield position to a pass through section of the rotor.
5 Reverse the operation to disengage the bayonet fitting.
6 Repeat the function test three times to ensure smooth operation.
