BRUSH REPLACEMENT
NOTE: Replace brushes one brush at a time.
1. Remove the hopper bag from the sweeper.
2. Loosen hex bolts and lock nuts on two single brush
retainers which clamp one brush to the double brush
retainers. DO NOT loosen or remove bolts which
fasten double brush retainers to brush shaft.
3. Slide the brush out of the retainers, noting on which
side of the brush the bristles overlap.
4. Install new brush, making sure the bristles overlap on
the same side of the brush as before.
SERVICE AND ADJUSTMENTS
GEAR AND DRIVE PIN SERVICE
IMPORTANT: Do Not remove both wheels at the same
time to avoid mixing of parts. (The pinion gears are not
interchangeable. The ratchet end of the gears is marked
"R" or "L".) Make notes on the position of all parts before
removing them.
• Remove the hub cap to expose the head of the bolt.
• Remove the bolt, washer, nut and step spacer.
• Remove the wheel and washer from the axle.
• To remove the larger 27 tooth gear, remove the
retaining ring and then remove the gear and washers.
• To remove the smaller pinion gear, remove the
retaining ring and then remove the gear, the drive
pin (located in the brush shaft), the washers and the
spacer.Seegure22.
• Clean all parts and replace worn parts.
• Lightly grease the shafts and the axle.
• Lightly grease the drive pin and the ratchet teeth
inside the pinion gear. Reassemble the drive pin,
pinion gear, the 27 tooth gear and the washers onto
the shafts. Lightly grease the teeth of both gears.
• Lightly grease the gear teeth on the wheel and then
reassemble the wheel, bolt and washers. Assemble

the nut securely.
• Repeat on the other end of the sweeper.
• Check that the brushes rotate only during forward
motion of the sweeper. If the brushes are driven in
both forward and reverse, the drive pin is jamming.
If the brushes are driven only in reverse, the pinion
gears have been switched.
