Disassemble Starter and Diagnose Internal Issues

Willys Jeep Rescue...starter problems!! 30 years of grime!
What happens here
The starter is placed on a workbench for further inspection and disassembly. The brush compartment cover is unscrewed (using pre-Phillips head screws), revealing accumulated dirt and debris. Further disassembly involves removing more screws to separate the starter casing and access the internal components. Inside, significant grime, bugs, and other nasty material are found. The commutator, where the brushes make contact, shows wear, and the brushes themselves are heavily worn and appear 'roached out.' An incorrect brush rebuild kit was obtained, and evidence of previous makeshift repairs (electrical tape) on the internal windings is observed. Due to these findings, a decision is made to have the starter professionally rebuilt rather than attempting a DIY repair.
Goal: Identify the specific internal failures of the starter motor.
Tools and materials
- Brush Rebuild Kit — Intended for replacing worn brushes (found to be incorrect)
- Pliers — Manipulating small springs and stuck components
- Sandpaper — Cleaning the commutator surface (though not used for final rebuild)
- Screwdriver — Removing retaining screws
- Starter Motor — The component being disassembled and inspected
