196Service Manual – SC5000 34 - Scrub System, Cylindrical
Brush Drive Belt
Brush Motor
The initial procedure for removing the brush motor is the same as replacing the drive belt. Lowering the
scrub deck is optional for replacing the belt, but it is required for removing the motor.
1. Although not required for belt removal, you may choose
to lower the scrub deck to provide better visibility of the
belt drive system and access to the motor.
a. Press the scrub button to lower the scrub deck.
b. When the deck is lowered, press the E-stop button to
disable all motors.
c. Disconnect the main battery connector under the
seat.
2. Press down on the latch release (A), and open the side
squeegee (B).
3. Remove the 9 screws (C) that secure the belt
cover (D) to the drive housing, and remove
the cover.
The drive belt is removed with a method
frequently referred to as “Walking” the belt off.
To get this process started, a shop towel is used
to ex the belt away from the pulley.
4. Loop a shop towel around the drive belt
above the lower pulley.
5. Using a 3/8” ratchet, turn the pulley
counterclockwise, while simultaneously
pulling back on the towel.
6. Continue turning the pulley while the towel
follows the belt around the pulley, and exes
the trailing end of the belt off of the pulley.
