Caution: Do not exert excessive upward pressure on the drive pulleys as the belts
are removed. This will bend the gear shaft which extends through the rear plate
bearing
Alternative belt removal technique
Follow steps in Changing the transparent belts on page 7-1 and then proceed with the
following two steps.
1
After the upper belt rocking idler and lower belt idler are removed, then the upper and lower pul-
leys near the sample tray can be removed (do not remove the drive pulleys).
Grasp each pulley near each end when they are being removed because they are
heavy. Dropping one end may cause severe damage.
2 After the belts are placed over the drive pulleys, slide the upper and lower pulleys through the
belts and insert the pulley shaft into the rear plate bearing.
Be sure that the peripheral end groove is toward the front and that it rests in the pul-
ley support bracket.
Replacing the transparent belts
1
Slide the lower belt onto the pulleys.
This requires repeated manipulation at the support brackets because these brackets
partially obstruct installation. Then slide the upper belt onto the upper pulleys.
2 Replace the lower belt idler.
Be certain that the peripheral end groove is toward the front and rests on the idler
support bracket.
3 Replace the upper belt rocking idler.
Be certain that the notch on the idler end plate rests on the rocking idler support
post.
4
Connect the fluorescent tube power connector if it was separated when the belts were removed.
5 Replace the front plate.
This requires repeated manipulation at the pulley and idler shafts to insure proper
alignment into the front plate bearings.
6
Replace all front plate screws.
