Removing and Installing Non-Segmented
Wheel for Cleaning (62M075, 120 Units) —
Non-segmented energy transfer wheels include the shaft and
are secured to two wheel support beams by two flange bearings
with locking collars. See Fig. 85.
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 two set screws on each of the two wheel
bearings. See Fig. 85.
Installing Wheel Segments (62M170-950
Units)
NOTE: Both installation and removal procedures must be per-
formed from the pulley side of the cassette.
NOTE: The 62M040-120 units contain non-segmented wheels
which must be completely removed to be cleaned.
1. Begin by positioning one segment opening at the top of
the cassette. Unlock and open the segment retaining
brackets on both sides of the selected segment opening.
2. Holding the segment as vertical as possible and
centered between spokes, insert nose of segment down-
ward between the hub plates. See Fig. 87.
NOTE: The face of the segment, with the imbedded
stiffener (vertical support between nose and rim end of
segment) must face the motor side of the cassette. See
Fig. 88.
3. Ease the segment downward until its outer rim clears the
inside of the wheel rim. Then press the segment inward
against the spoke flanges.
4. Close and latch segment retaining brackets to the position
shown in Fig. 89. Make certain the retaining bracket is
fully engaged under the catch.
5. Slowly rotate, by hand, the first installed segment to the
bottom of the cassette, then install the second segment
opposite the first. Repeat this sequence with the two
installed segments rotated to the horizontal position to
balance the weight of installed segments. Continue this
sequence with the remaining segments.
When replacing wheel, retighten the 4 bearing set screws.
Premature bearing failure could result.
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
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. 86.
