SERVICE AND ADJUSTMENTS

BRUSH REPLACEMENT

NOTE: Brush replacement should be done one brush at

atime.

Remove the hopper bag from the sweeper.

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 figure 26.

Slide the brush out of the retainers, noting on which side of the brush the bristles overlap. See figure 26.

Install new brush, making sure the bristles overlap on the same side of the brush as before. See figure 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 sprockets are not interchangeable.) Make notes on the position of washers and snap rings during disassembly.

Remove only one wheel from the sweeper.

Remove the retaining rings and washers which hold the ratchet gear on the brush shaft.

Slide the gear off of the brush shaft. (Look for the drive pin, which may fall out of the brush shaft when the ratchet gear is removed.) See figure 27.

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.

Lightly grease the shaft and fill the ratchet gear with grease. Assemble the ratchet gear back onto the shaft.

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.

Remove the second wheel and repeat the procedure.
