How do I prevent the injector from breaking during removal?
Always ensure the extractor is perfectly aligned and that the engine is at the correct working temperature if specified by the manufacturer.
Troubleshooting
Injector remains stuck after applying force
Apply a high-quality penetrating oil around the base of the injector and allow it to soak for at least 30 minutes before attempting extraction again.
Extraction tool slipping from the injector body
Verify that you are using the correct size adapter for the specific engine displacement and that the tool is seated flush against the injector shoulder.

Maintenance Tips:
- Cleaning: After every use, wipe all adapters and pullers with a clean shop rag to remove residual fuel and grime.
- Lubrication: Apply a light coat of machine oil to the threads of the slide hammer and extraction tools to prevent oxidation.
- Inspection: Regularly check the teeth and engagement edges of the extractors for wear or rounding; worn tools can slip and damage the injector housing.
- Storage: Keep the kit in a dry, low-humidity environment to prevent corrosion of the hardened steel components.
