BRUSH REPLACEMENT
SPROCKET, CHAIN AND PAWL SERVICE
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.

iMPORTANT: Do Not remove both wheels at the same
time to avoid mixing of parts. (The R.H. and L.H. ratchet
sprockets are not interchangeable.) Make notes on the
position of all parts before removing them.
• Remove hub cap, nylock nut and washer on outside
of wheel and then remove wheel.
Remove the dust cover by removing the two #12
screws which fasten it to the wheel housing. (It is not
necessary to remove the dust cover if you are only
cleaning and lubricating the chain and sprockets.)
Remove the retaining rings and washers which hold
the sprockets onto the shafts.
Remove the chain and both sprockets, holding them
in position and sliding them off both of the shafts.
(Look for the drive pin, which may fall out of the brush
shaft when the ratchet sprocket is removed.) See
figure 22.
To reassemble, insert the drive pin through the hole
at the end of the brush shaft. Make sure the pin slides
back and forth easily in the shaft.
Lightly grease both shafts and the chain, and fill the
ratchet sprocket with grease. Assemble the chain with
both sprockets back onto the shafts.
Lightly grease the axle 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 and clean and lubricate the drive pin
and ratchet gear.
