Step 10.
At electronics chassis, pull yoke cables, high-votage lamp wires
and ground wire through yoke. Wiring may remain attached
within electronics chassis.
Step 11.
Using 5/32 inch Allen wrench, loosen hex screw on yoke collar
and remove from yoke tube.
Step 12.
Loosen pan belt tension to free belt from pulley.
Step 13.
Using, 7/64 inch T-handle Allen wrench, loosen four 4-
40x7/16”SCB screws on pan driven pulley. Use hole in pan/fan
housing to reach screws (turn yoke as necessary).
Note: On some older models, pan/fan housing may not have access hole.
Access hole may be created by replacing yoke collar and drilling
approximately 1/4 to 3/8 inch hole in pan/fan housing next to outer edge of
yoke collar location.
Step 14.
Slide yoke assembly free of electronics chassis.
Step 15.
Temporarily slide pan pulley onto tube of replacement yoke to
verify proper fit. Remove pan pulley. Repeat with yoke collar.
Remove.
Step 16.
Slide pan tube of replacement yoke through first bearing and
into electronics chassis. Install pan pulley and belt and slide
yoke pan tube into second bearing.
Step 17.
While placing pressure on yoke from below, install pan shaft
collar. Make sure yoke pan tube is completely inserted in
electronics chassis and tube extends past pan shaft collar
slightly. Tighten pan shaft collar with 5/32 inch Allen wrench.
Ensure hub clamp of pan shaft collar is firmly set against
bearing and there is no vertical movement of yoke pan tube.
Step 18.
Place 0.06 inch spacers between pulley and chassis lid. If
spacers are not available, two medium size tie wraps can be
placed flat on both sides of the pulley (one on each side) to act
as temporary spacers.
