Injector Benzine Ke-Jetronic – R107 C124 A124 W124 S124 R129 W126 C126 W463

Injectoren voor KE-Jetronic injectiesystemen zijn een belangrijk onderdeel van het mechanische injectiesysteem. Deze injectoren zijn technisch relatief eenvoudig opgebouwd, maar bevatten wél precisieonderdelen die na verloop van tijd slijten. Daarom zijn KE-Jetronic injectoren slijtageonderdelen die in bij oldtimers en klassiekers op tijd vervangen moeten worden.

Inside each injector is a small spring that ensures the injector opens and closes at the correct moment. Additionally, there is a small strainer inside designed to retain fine dirt. Because this strainer cannot be removed (without completely disassembling the injector) and because injectors cannot be cleaned against the flushing direction, these injectors are practically difficult to clean. Replacement is therefore usually the best and most reliable solution.

What to look out for when replacing injectors 

1. Always work cleanly and carefully

• Prevent dirt or dust from entering the injection system.
• Never overtighten pipes.

2. Always check the fuel tank for rust or contamination first.

• Rust particles or dirt in the fuel tank can immediately damage the new injectors; this is not covered by the product warranty.
• Therefore, always check the tank and the fuel lines for contamination and damage first, and clean or replace if necessary.

3. Always replace the fuel/petrol filter

• New injectors must never be installed behind an old or clogged filter.
• A clean filter prevents immediate contamination of the new injectors.

4. Always replace injector sleeves and/or mounting rubbers

• Bad or old sleeves and seals cause false air, leading to poor engine performance.
• See also the article on fuel distributors for more explanation about false air.

5. Check for leaks after installation

• Start the engine and check all connections for fuel leaks.
• Ensure that pipes seal correctly and without problems.
• controleer ook op vals lucht lekkages

New injectors can sometimes stick.

It sometimes happens that new injectors may stick slightly at first.

In practice, this problem usually resolves itself after short use.

Advice 

Our advice is to always test new injectors before installation. In our own Mercedes Classic Garage, we therefore always test the spray pattern of new injectors before installation.

Tip: For a small additional fee, we can pressure test the injectors for you before shipment, so you can be certain that they open and close correctly and have the correct flow rate.

Follow all prescribed procedures and have the work performed by a recognized specialist to ensure correct installation and, consequently, faultless operation of the high-quality replacement parts. Incorrect installation or minor contamination can immediately lead to malfunction of the injection system.
