The Maytronics Dolphin Nautilus Tracks are the belts that connect the gear on the motor shaft to the drive gears on each end of the Brushes. There are two tracks, One on each side. Over time these tracks wear and stretch to the point where they have to be replaced. This guide shows you the steps required to replace these tracks.
UNSCREW LEFT SIDE PANEL - To access the Tracks, you will need to remove the outside shell of the Cleaner. Turn the Cleaner on its side and remove the 4 screws that hold the blue panel to the left side of the cleaner. Use a Phillips head screwdriver to manually remove the screws. You risk the chance of stripping the plastic screw sockets if you use a power drill.
REPLACE LEFT SIDE WHEELS AND PULLEY - Replace the two Guide Wheels and Drive Pulley on the left side using the same procedure listed above for the right side. The procedure is the same except there is no Hexagon Adapter. The motor only drives the right side.
REPLACE LEFT SIDE PANEL - Place the Left Side Panel over the posts of the Drive Pulley and the 2 Guide Wheels. The Drive Pulley will be cocked at an angle because of the tension of the Track. You may have to use a flat screwdriver to pull the edge of the Drive Pulley down in order to fit the Side Panel over its post.
