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 only one wheel from the sweeper.
2. Remove the retaining rings and washers which hold the
ratchet gear onto the brush shaft.
3. (Figure 26) 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 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 to clean and lubricate the
drive pin and the ratchet gear.
BRUSH REPLACEMENT
NOTE: Brush replacement should be done one brush at
a time.
1. Remove the hopper bag from the sweeper.
2. (Figure 25) 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.
3. (Figure 25) Slide the brush out of the retainers, noting
on which side of the brush the bristles overlap.
4. (Figure 25) Install new brush, making sure the bristles
overlap on the same side of the brush as before.
1. Brushes set too low.
2. Brushes are jammed.
3. Wheels are jammed.
Wheels skid when sweeping. 1. Adjust height till brushes are 1/2" down into grass.
2. Stop sweeper. Remove obstruction.
3. Remove one wheel at a time to check for obstruction or
damage. Refer to Service and Adjustments section.
