SERVICE AND ADJUSTMENTS
BRUSH REPLACEMENT
NOTE: Brush replacement should be done one brush at
a time.
1. Remove the hopper bag from the sweeper.
2. Loosen only the two hex bolts and lock nuts which clamp
one brush in a brush retainer. Do not loosen or remove
the bolts which fasten the brush retainers to the brush
shaft. See figure 25.
3. Lift the brush out of the retainers, noting on which side
of the brush the bristles overlap. See figure 25.
4. Install new brush, making sure the bristles overlap on
the same side of the brush as before. See figure 25.
5. Tighten the two hex bolts and lock nuts to clamp the
new brush in place before removing the next brush.

WHEEL GEAR AND PAWL SERVICE
IMPORTANT: Do not remove both wheels at the same time
to avoid mixing of parts. (The R.H. and L.H. ratchet gears are
not interchangeable.) Make notes on the position of washers
and snap rings during disassembly.
1. Remove only one wheel from the sweeper.
2. Remove the retaining rings and washers which hold
the ratchet gear onto the brush shaft.
3. Remove the gear by sliding it off the brush shaft. (Look
for the drive pin, which may fall out of the brush shaft
when the ratchet gear is removed.) See figure 26.
4. To reassemble, insert the drive pin through the hole
near the end of the brush shaft. Make sure the pin
slides back and forth easily in the shaft. See figure 26.
5. Lightly grease the shaft and fill the ratchet gear with
grease. Assemble the ratchet gear back onto the shaft.
See figure 26.
6. Lightly grease the axle and the gear teeth on the
wheel, and then reassemble the wheel. The brushes
should rotate only during forward rotation of the wheel.
If the brushes are driven (rotated) by both forward and
reverse rotation of the wheel, the drive pin is jamming
in the ratchet gear. Disassemble to clean and lubricate
the drive pin and the ratchet gear. See figure 26.
7. Remove the second wheel and repeat the procedure.
