Figure 7-1. LI-3100C with front plate removed. (A) Fluorescent tube power connector, (B)
pulley support brackets, (C) upper belt rocking idler, (D) lower belt idler, (E) proper loc-
ation of pulley peripheral end grooves, lower belt idler peripheral end groove, and the end

Remove the hexagonal socket screws (7 total) which are directly contacting the instrument plate.
Other similar screws are visible on the front of the instrument which fasten the pul-
ley support brackets. Do not loosen those screws.
7 Remove the front plate slowly, keeping it parallel to prevent binding on the shafts.
Be certain that all pulleys and idlers remain in place, resting on the support brackets.
This is accomplished by repeatedly pressing the pulleys and idlers back into their
rear plate bearings.
Caution: Do not allow the upper belt rocking idler or the lower belt idler to drop
onto the mirror located directly beneath these components.
8 Draw the upper belt rocking idler and the lower idler outward to remove them.
9
Slide the belts outward to remove them.
