MAINTENANCE

WHEEL GEARS/PAWL SERVICE

IMPORTANT: Do not remove both wheels at the same
time to avoid mixing 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.

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.

5. Lightly grease the shaft and fi ll the ratchet gear with

grease. Assemble the ratchet gear back onto the shaft.

6. Lightly grease the axle and the gear teeth on the

wheel and then reassemble the wheel. The brushes
should rotate only during forward movement. If the
brushes rotate by both forward and reverse movement,
the drive pin is jamming in the ratchet gear. Dissamble,
clean and lubricate the drive pin and ratchet gear and
then reassmble wheel.

7. Remove opposite wheel and repeat steps 1-6 for that

wheel.

The bearings in the sweeper have been prelubricated at
the factory. It is recommended that a few drops of light
oil be added to the brush shaft bearings twice a year.
The wheels should be removed to clean gears every two
years. After cleaning, apply an even coat of light grease.
See fi gures 11 and 12.

NOTE:

To remove the wheel, pop off hub cap with a screw
driver and remove retaining "E" ring and fl at washer.

BRUSH REPLACEMENT

brush retainers through brush shaft.

4. Loosen hex bolts and hex lock nuts from single brush

retainers. See fi gure 12. Slide brush out of retainers,
making not of over-lap bristles position.
