Fuel Injectors

Fuel Injectors

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.

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

Special tools, testers and auxiliary items required

• Round File Approximately 6 mm

- File the semicircle as shown in the illustration. The semicircle 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 (Old Version)





1 Combustion chamber seal ring (Teflon seal), replace, the ring must not be greased or handled with any other lubricants when installing.
2 The support ring is being replaced by an intermediate ring. See fuel injector (new version).
3 Fuel injector
4 Spacer ring, replace if damaged
5 O-ring (replace, lubricate lightly with clean engine oil when installing)
6 Support ring (via this support ring, fuel rail utilizes the force to hold the fuel injector in place in the cylinder head).

Removing

- Remove the intake manifold with the fuel rail. Refer to => [ Intake Manifold with Fuel Rail ] Intake Manifold with Fuel Rail.

• Remove the fuel injectors if they remain attached in the fuel rail.

- Cover the intake passages with a clean cloth.

- 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 bolt - 1 - and remove the fuel injector.

• Pay attention to the intermediate rings.

• The Teflon seal must always be replaced before installing the fuel injector. Refer to => [ Fuel Injector Teflon Seal ] Fuel Injector Teflon Seal.

Installing

• The Teflon seal for the fuel injector may not be oiled or greased.

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

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






- Teflon seal removing and installing. Refer to => [ Fuel Injector Teflon Seal ] Fuel Injector Teflon Seal.

- Assemble the fuel injector with the parts from the repair kit.

- Press the fuel injector by hand into the cylinder head (free of oil and grease) as far as the stop. Make sure the fuel injectors are positioned - arrow - correctly inside the cylinder head.






• If it is difficult to install the fuel injector by hand use the puller (T10133/2A) - 2 - with the hammer (T10133/3).






- Install the support ring onto the fuel injector.

- Lightly coat the O-rings for the fuel injector with clean engine oil before installing

- Install the intake manifold with the fuel rail. Refer to => [ Intake Manifold with Fuel Rail ] Intake Manifold with Fuel Rail.
