Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure you have a clean workspace and safety gear (gloves, goggles).

2. Remove Starter

Locate the starter on the engine; it is typically mounted on the lower side of the engine block.
Remove the heat shield (if applicable) using a socket set.
Disconnect the electrical connectors from the starter, noting their positions.
Unbolt the starter using the appropriate socket size and remove it from the engine.

3. Disassemble Starter

Use a torque wrench to carefully remove the end cap of the starter.
Extract the armature and field coils from the starter housing.
Inspect brushes for wear; they should not be shorter than the specified length (check service manual for specifics).
Remove and clean the commutator with a fine-grit sandpaper, ensuring it is smooth and free from grooves.

4. Replace Components

If brushes are worn, replace them with new ones, ensuring they fit securely.
Inspect and replace any damaged or corroded wiring.
Reassemble the starter by reversing the disassembly steps, ensuring all parts are seated correctly.

5. Reinstall Starter

Position the rebuilt starter back onto the engine block.
Secure it with bolts to the manufacturer’s torque specifications.
Reconnect the electrical connectors in their original positions.
Reinstall the heat shield if it was removed.

6. Final Checks

Reconnect the negative battery terminal.
Test the starter by turning the ignition key to the "start" position.
