What happens here
The critical issue is revealed: the magnets inside the motor casing have come loose due to degraded adhesive and rust, which is preventing the motor from operating correctly. The presenter outlines the repair strategy as reattaching these magnets rather than buying an expensive new pump. He thoroughly cleans the inside of the motor casing by scraping off old glue and rust with a flat-head screwdriver, followed by using a wire brush attachment on a drill to ensure a clean surface. He also cleans the commutator on the armature with fine sandpaper and uses a specialized file tool to clean the grooves between the commutator segments, ensuring good electrical contact for the brushes. Finally, he cleans all parts with brake cleaner.
Goal: This step involves repairing the motor by reattaching loose magnets and meticulously cleaning all internal motor components to restore proper function.
