Repairing a Stripped Spark Plug Head
Materials:
- Spark plug extractor kit
- Pliers
- Thread repair kit (optional)
Instructions:
1. Gather Your Tools: Make sure you have all the necessary tools before starting the repair.
2. Remove the Spark Plug Wire: Disconnect the spark plug wire from the spark plug.
3. Insert the Extractor: Select the appropriate extractor size for the spark plug and insert it into the stripped head.
4. Turn the Extractor: Using pliers, gently turn the extractor counterclockwise to loosen the spark plug. Avoid using excessive force.
5. Remove the Spark Plug: Once the spark plug is loose, carefully remove it from the cylinder head.
6. Inspect the Thread: Examine the threads in the cylinder head for any damage. If the threads are badly damaged, you may need to use a thread repair kit to restore them.
7. Install a New Spark Plug: Install a new spark plug with the correct torque specifications.
Using a Thread Repair Kit
If the threads in the cylinder head are damaged beyond repair, you can use a thread repair kit to restore them.
Materials:
- Thread repair kit
- Drill
- Tap
Instructions:
1. Drill the Hole: Use the drill bit provided in the kit to drill out the damaged threads.
2. Tap the Hole: Use the tap to cut new threads into the hole.
3. Insert the Insert: Screw the thread insert into the tapped hole.
4. Install a New Spark Plug: Install a new spark plug with the correct torque specifications.
When Replacement Is Necessary
In some cases, the damage to the spark plug head or threads may be too severe to repair. If you encounter any of the following situations, replacement is the best option:
- The extractor cannot grip the stripped head.
- The threads in the cylinder head are severely damaged.
- You are unable to remove the stripped spark plug after using an extractor.
