Non-segmented energy transfer wheels include
the shaft and are secured to 2 wheel support beams by 2 flange
bearings with locking collars. See Fig. 31.
To remove the energy transfer wheel, follow Steps 1-4
below. Reverse procedure for wheel installation.
1. Pull the wheel with shaft straight out of the motor side
wheel support beam and bearing. Handle wheel with care
to prevent distorting of the wheel.
2. Remove the pulley side wheel support beam with bearing
by removing the 4 support beam screws.
3. Remove the belt from the pulley and position temporarily
around the wheel rim.
4. Loosen the 2 set screws on each of the 2 wheel bearings.

CAUTION
When replacing wheel, retighten the 4 bearing set screws.
Premature bearing failure could result.
WARNING
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
CAUTION
Weight of the installed segment will cause the wheel to
accelerate in rotation. Failure to maintain control of the
wheel rotation while installing all segments could cause
severe injury to fingers or hand caught between revolving
spokes and the bearing support beam. Handle of hammer,
or other stop, should be inserted through spokes and above
or below bearing support beams to limit rotation of unbal-
anced wheel. See Fig. 33.
