BRUSH REPLACEMENT

NOTE: Brush replacement should be done one brush at

a time.

1. Remove the hopper bag from the sweeper.

2. 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 26.

3. Slide the brush out of the retainers, noting on which

side of the brush the bristles overlap. See ﬁ gure 26.

4. Install new brush, making sure the bristles overlap on

the same side of the brush as before. See ﬁ gure 26.

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 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 pawl, which may fall out of the brush shaft when

the ratchet gear is removed.) See ﬁ gure 27.

4. To reassemble, insert the pawl through the rectangular

hole in the brush shaft. Make sure the pawl is turned so

that the ﬂ at side of the pawl will press against the ﬂ at

side of the internal teeth in the ratchet gear.

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 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 pawl is assembled incorrectly and must
