FAQs
What specific engine types does this adaptor work with?
The Laser 7855 adaptor is designed for 1.3 Common Rail Diesel (JTD) engines equipped with paired Bosch solenoid type injectors.
Do I need any other tools besides the adaptor?
Yes, you will need Laser Part No. 4761 to remove the solenoid internals before attaching this adaptor. You will also need a compatible Air Hammer Extractor (Laser Part No. 6092) or Slider Hammer (Laser Part Nos. 5850 or 4811).
Which vehicle models are covered by this adaptor?
It covers various Alfa Romeo, Fiat, Ford, and Lancia models. Specific examples include Alfa Romeo Mito, Fiat 500, Doblo, Fiorino, Punto, Idea, Panda, Quobo, Tipo, Uno; Ford Ka; and Opel/Vauxhall Agila, Astra, Combo, Corsa, Meriva, Tigra & Zafira.
Can this adaptor be used on gasoline engines?
No, this adaptor is specifically designed for diesel fuel injectors, not gasoline (petrol) injectors.
What is the primary benefit of using this tool?
The primary benefit is enabling a safe and efficient removal of seized or stubborn Bosch solenoid type diesel injectors from the specified 1.3 JTD engines, reducing the risk of damage and saving mechanic time.
How should I clean and store the adaptor?
Clean the adaptor with a degreaser and a clean cloth after each use. Store it in a dry place to prevent rust and corrosion.
What should I do if the injector is very difficult to remove?
Ensure the solenoid internals are fully removed and that the adaptor is seated correctly. Apply force steadily. If still stuck, consider using a penetrating oil around the injector base and allowing it time to work before attempting removal again. Always use controlled force to avoid damage.
Troubleshooting
Adaptor does not fit injector
Verify that you are working on a 1.3 JTD engine with Bosch solenoid type injectors. Ensure the solenoid internals have been completely removed using the correct tool (Laser Part No. 4761).
Injector does not budge after applying force
Ensure the extraction tool is securely attached to the adaptor. Apply force smoothly and steadily. If the injector remains stuck, re-evaluate for carbon buildup or corrosion and consider using a penetrating lubricant. Ensure no part of the injector is still mechanically attached.
Damage to injector or cylinder head
This typically occurs from uneven or excessive force. Ensure you are using controlled movements with the slider or air hammer. If damage has occurred, stop immediately and assess the extent of the damage.
