GEAR AND PAWL REPLACEMENT (Figure 30)
IMPORTANT: Do not remove both wheels at the same time. (The right and left gears are not
interchangeable.) Note the position of washers and snap rings during disassembly.
• Remove only one wheel at a time from the sweeper.
• Remove the retaining rings and washers which hold the gear on the brush shaft.
• Remove the gear and drive pin. (The drive pin may fall out of the brush shaft when the gear is removed.)
• To reassemble, insert the drive pin through the hole in the brush shaft. Make sure the pin slides
back and forth easily in the shaft.
• Lightly grease the brush shaft and fill the gear with grease. Assemble the gear back onto the shaft.
• Lightly grease the axle and the gear teeth on the wheel, and then reassemble the wheel. Rotate
the wheel in both directions. 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 gear. Disassemble to clean and lubricate the drive pin and the gear.
• Remove the second wheel and repeat the procedure.
