Disassemble, Clean and Replace Brushes

What happens here

After applying penetrating oil, the creator disassembles the motor further, revealing heavy rust and water damage inside the motor housing and on the armature. He uses a sanding sponge to clean the commutator (rotating part) and a wire brush (attached to a Milwaukee drill) to clean the internal casing where the magnets are located. He then replaces the old, corroded carbon brushes with new ones from the brush kit, ensuring they slide freely into their slots.

Goal: Clean internal motor components and install new brushes
