engages the notch at the end of the shaft when reinstalling the wheel.

4.Pull the wheel straight off the shaft. Handle wheel with care to prevent distorting of the wheel.

Removing and Installing Non-Segmented

Wheel for Cleaning (62ECC and 62E2C Units) — 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. See Fig. 31.

CAUTION

When replacing wheel, retighten the 4 bearing set screws. Premature bearing failure could result.

Removing Wheel Segments for Cleaning (62ECD, 62ED-EU, 62E2D, and 62E3-E6 Units)

1.Unlock and open the segment retaining brackets on both sides of the selected segment opening. Refer to Fig. 32.

2.Gently lift segment outward.

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.
