With time and use the Drive Belts may become stretched, or worn to the point where the Cleaner starts operation erratically. It may move sporadically, or not climb the wall, or not clean the entire pool floor. This guide shows you how to locate and replace the Aquabot Classic Robotic Pool Cleaner Drive Belts. Note, the Drive Belts are different from the Drive Tracks. The Drive Tracks move the Cleaner along the pool floor, The Drive Belts are internal and connect the Drive Pulley off the motor shaft to the Wheel Tubes that drive the Drive Tracks.
BUY PARTS - If you need to replace one Drive Belt, you should replace the pair of belts. Order them ahead of time so you have them on hand when you take the cleaner apart.
REMOVE DRIVE TRACKS - See our guide on "How to Replace an Aquabot Classic Robotic Pool Cleaner Drive Track". You only have to remove the Drive Track on the side where the power cord enters the cleaner.
INSTALL NEW REAR DRIVE BELT - Place the new rear Drive Belt around the back gears of the Wheel Tube and the Drive Pulley. Note: There is no difference between the rear and front Drive Belts. Make sure the teeth of the belt are pointing in so they engage with the gears. Check that the plastic washers are in front of both the Wheel Tube and the Drive Pulley.
PREP SIDE PLATE - Make sure the thicker end of each Stepped Sleeve Rollers is placed as shown so that the thicker end of the Roller will press down on each belt when reassembled. There are three Bushings, one on each end and one in the middle. The end Bushings are inserted from the bottom., the middle Bushing is inserted from the top as shown.
ATTACH SIDE PLATE - Place the Side Plate in position. Make sure three bushings haven't dropped out and the plastic washers are in place. Also, ensure that the Stepped Sleeve Rollers are placed outside the belt loops so that they press down on the belts when assembled. You may need an extra set of hands on this step to keep all the pieces in place.
