Over time the Disc Assemblies on your Zodiac T5 Suction Pool Cleaner may wear or crack and will have to be replaced. Also the Foot Pads should be replaced when the depths of the channels between the treads are 1/16" or less. This guide shows you how to replace the two Discs, the two Foot Pads and the Skid Plate.
VIEW DISCS - Turn the Cleaner on its back. This picture shows the location of the 2 Discs, the Skid Plate, and 2 Foot Pads that you will be replacing. The 2 Discs are secured onto the Zodiac X7 Cleaner with the two Foot Pads. The Foot Pads are released by sliding them out the front side of the Cleaner.
INSTALL FOOT PAD (1) - Place the arrow end of the new Foot Pad into the first slot of the new Front Disc. Then work the first slot over the front knob of the Foot Pad. You may have to use a flat headed screwdriver to pry this slot over the first know. The shiny side of the Front Disc should be down.
