wheeL Gears/Drive Pin 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.
See Figure 14.
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 fill 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. Disassemble, clean, and lubricate the drive pin
and ratchet gear and then reassemble wheel.
7. Remove the other wheel and repeat steps 1-6.

Brush replacement should be done one brush at
a time.
See Figure 15.
1. Remove the hopper bag from the lawn sweeper.
2. Tip the sweeper forward on the sweeper housing
for ease of brush replacement. Do not remove the
hex bolt from the double brush retainers through the
brush shaft.
3. Loosen the hex bolts and hex lock nuts from the
single brush retainers. Slide the brush out of the
retainers. Ensure you do not of overlap the position of
the bristles.
4. Install the new brush, making sure the over-lap
bristles are positioned the same as before and as
shown.
