NOTE: The 62EBA, 62EBC, 62ECC, 62E7A, 62E7C, and 62E2C 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. 34.

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. 36. 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 2 in- stalled segments rotated to the horizontal position to bal- ance the weight of installed segments. Continue this se- quence with the remaining segments.

Wheel Drive Motor and Pulley Replacement (62EC-EU and 62E2-E6 Units)

1.Disconnect power to wheel drive motor.

2.Remove belt from pulley and position temporarily around wheel rim.

3.Loosen setscrew in wheel drive pulley using Allen wrench and remove pulley from motor drive shaft.

4.While supporting weight of drive motor in one hand, loosen and remove 4 mounting bolts.

5.Install replacement motor with hardware kit supplied.

6.Install pulley to dimension shown in Fig. 37 and secure setscrew to drive shaft.

7.Stretch belt over pulley and engage in groove.

Belt Replacement

1.Obtain access to the pulley side bearing access plate. Remove 2 bearing access plate retaining screws and the access plate.

2.Using hexagonal wrench, loosen setscrew in bearing locking collar. Using light hammer and drift (in drift pin hole) tap collar in the direction of wheel rotation to unlock collar. Remove collar.

3.Using socket wrench with extension, remove 2 nuts which secure bearing housing to the bearing support beam. Slide bearing from shaft.

NOTE: Slight hand pressure against wheel rim will lift weight of wheel from inner race of bearing to assist bearing removal and installation. If not removable by hand, use bearing puller.

CAUTION

Protect hands and belt from possible sharp edges of hole in bearing support beam.

4.Using a wrench, remove diameter seal retaining screws or hub seal retaining screws. Remove diameter seals or hub seal from bearing beam. See Fig. 38.

5.Form a small loop of belt and pass it through the hole in the bearing support beam. Grasp the belt at the wheel hub and pull the entire belt down. Loop the trailing end of the belt over the shaft (Fig. 38 shows belt partially through the opening).
