BRUSH REPLACEMENT
NOTE: Brush replacement should be done one brush
at a time.
•
Remove the hopper bag from the sweeper.
•
Loosen the hex bolts and lock nuts on two single
brush retainers which clamp one brush to the double
brush retainers. Do Not loosen or remove the bolts
which fasten the double brush retainers to the brush
shaft. See fi gure 25.
•
Slide the brush out of the retainers, noting on which
side of the brush the bristles overlap. See fi gure 25.
•
Install new brush, making sure the bristles overlap on
the same side of the brush as before. See fi gure 25.

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.
•
Remove one wheel from the sweeper.
•
Remove the retaining rings and washers which hold
the ratchet gear onto the brush shaft.
•
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 fi gure
26.
•
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.
•
Lightly grease the shaft and fi ll the ratchet gear with
grease. Assemble the ratchet gear back onto the
shaft.
•
Lightly grease the axle and the wheel's gear teeth
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.
