Removing fuel injectors, in the event that they are stuck in the cylinder head

Special tools, testers and auxiliary items required

• Tool Set (T10133)

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

Modify puller (T10133/2) to create puller (T10133/2-A).

Special tools, testers and auxiliary items required

• Round file approximately 6 mm

- File 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.

The illustration shows the fuel injector.





1 Radial compensation, replace if damaged
2 Combustion chamber sealing ring (Teflon sealing ring), replaced ring must not be greased or handled with any other lubricants when installing.
3 Groove on fuel injector
4 Spacer ring, replace if damaged
5 O-ring (replace, coat lightly with clean engine oil when installing)
6 Support ring (via this support ring, the fuel rail utilizes the force to hold the fuel injector in place in the cylinder head).

• With fuel injector installed, the radial adjustment - 1 - is clipped into the support ring - 6 -. To remove the fuel injector, the support ring must be separated from the fuel injector in order to install the puller (T10133/2) into the indentation on the fuel injector - 3 -.





- Cover open intake channels with a clean rag.

- Disconnect electrical harness connector at fuel injector that is to be removed.

- Bend retaining tabs of radial compensation to the side using a screwdriver and pull off support ring from fuel injector.





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





- Then position trim removal wedge (T10133/16) and remove fuel injector by loosening bolt - 1 -.

• The combustion chamber seal must always be replaced before re-installing the fuel injector. Refer to => [ Teflon Combustion Chamber Seal, Replacing ] Teflon Combustion Chamber Seal, Replacing.
