Fuel Injectors, Removing and Installing

Fuel Injectors, Removing and Installing

Special tools, testers and auxiliary items required

• Tool set (T10133)





• The puller (T10133/2) was changed. It is now called the puller (T10133/2A). If the new tool is not available, the old one can be modified.

Remover (T10133/2) has been changed to Remover (T10133/2A)

Special tools, testers and auxiliary items required

• Round file approximately 6mm

- File the semi-circle as shown in the illustration. The semi-circle allows the tool to slide farther onto the fuel injector, thus providing the tool with a larger contact surface.





- Mark the modified tool with an "A" at the end of the tool number.

Fuel injector, individual parts





1. Combustion chamber sealing ring (Teflon sealing ring), replace, the ring must not be greased or handled with any other lubricants when installing.

2. Intermediate ring

3. Fuel injector

4. Support ring

5. O-ring (replace, coat lightly with clean engine oil when installing)

6. Support element (the fuel rail wields force via the support element to hold the fuel injector tightly in the cylinder head)

Removing

- Remove the intake manifold with the fuel rail => [ Intake Manifold with Fuel Rail, Removing and Installing ] Intake Manifold With Fuel Rail, Removing and Installing.

• If the injector valves remain attached in the fuel rail, then pull them out.

- Cover the intake channels with a clean rag.

- Remove the support element - A - downward and disconnect the connector - arrows - from the fuel injectors.





- Position the puller (T10133/2A) in the groove on the fuel injector.





- Mount the removal tool (T10133/16), turn the screw - 1 - and remove the fuel injector.

• Pay attention to the intermediate rings.

• The combustion chamber seal must always be replaced before re-installing the fuel injector => [ Teflon Seal on Fuel Injector, Replacing ] Teflon Seal on Fuel Injector, Replacing.

Installing

• The Teflon sealing ring of fuel injector may not be oiled or greased.

• Possibly an opened intake valve hinders the cleaning. In this case, engine must be turned further by hand using a screw wrench on the crankshaft.

- Thoroughly clean bores for high pressure fuel injectors in cylinder head using nylon brush (T10133/4).





- Replace O-ring and Teflon sealing ring of fuel injector => [ Teflon Seal on Fuel Injector, Replacing ] Teflon Seal on Fuel Injector, Replacing.

- Install the fuel injection with the intermediate ring again - 2 -.





- Use the Remover (T10133/2A) - 2 - to push the fuel injector all the way into the hole in the cylinder head.





- Make sure fuel injectors are positioned correctly in cylinder head.





- Install the intake manifold with the fuel rail => [ Intake Manifold with Fuel Rail, Removing and Installing ] Intake Manifold With Fuel Rail, Removing and Installing.
