Can You Clean a Starter Motor to Make It Work Again?

Understanding Starter Motor Issues

Starter motors can often develop problems due to accumulated dirt, grime, and wear over time. Before rushing to replace your starter, it’s worth considering a thorough cleaning and inspection. This process can potentially restore functionality and save you money on unnecessary replacements.

Steps to Clean Your Starter Motor

1. Safety first: Disconnect the battery before removing the starter motor.

2. Remove the starter: Locate and remove the mounting bolts, then carefully detach the starter from the engine.

3. Disassemble the starter: Take apart the main components, including the solenoid, end caps, and brush assembly.

4. Clean thoroughly: Use electrical contact cleaner or a degreaser to remove dirt and buildup from all parts.

5. Inspect components: Check brushes, commutator, and bearings for wear or damage.

6. Lubricate moving parts: Apply a thin layer of silicone lubricant to necessary areas.

7. Reassemble carefully: Ensure all parts are correctly aligned and secured.

Benefits of Cleaning Your Starter Motor

When to Consider Replacement

While cleaning can often revive a starter motor, sometimes replacement is necessary. Consider replacing if you notice:
