Teflon(R) Combustion Chamber Seal

Teflon(R) Combustion Chamber Seal

Special tools, testers and auxiliary items required

• Puller (T10133/2A)

• Hammer (T10133/3)

• Nylon Brush (T10133/4)

• Assembly Cone (T10133/5)

• Guide Sleeve (T10133/6)

• Calibration Sleeve (T10133/7)

• Calibration Sleeve (T10133/8)

• Always replace the combustion chamber seal before installing a fuel injector.

Replacing

- Remove the fuel injector. Refer to => [ Fuel Injectors ] Fuel Injectors.

- Carefully remove the old combustion chamber seal with the appropriate tool (for example cut the seal open with a razor blade, spread it outward with a small screwdriver and remove it forward). When doing this, make sure not to damage the groove and circumferential rib in the groove base.

• If the groove is damage, the fuel injector must be replaced.

- Clean off any combustion residue on the seal groove and on the shaft of the fuel injector with a clean cloth before installing the new combustion chamber seal.

- Place the (T10133/5) with the new combustion chamber seal - 1 - onto the fuel injector - 2 -.






- Slide the combustion chamber seal further onto the (T10133/5) using (T10133/6) until the combustion chamber seal locks into the groove in the seal. When doing this, do not use any lubricants.






• When pushing the combustion chamber seal onto the fuel injector, the combustion chamber seal spreads open. Therefore after pushing it on, it must be tightened again in 2 steps, as follows.

- Press the (T10133/7) with a gentle turning movement (approximately 180°) all the way onto the fuel injector.






- Turn the (T10133/7) in the opposite direction and remove it.

- Press the (T10133/8) with a gentle turning movement (approximately 180°) all the way onto the fuel injector.






- Turn the (T10133/8) in the opposite direction and remove it.

- Replace the O-ring on the fuel injector. Coat the O-ring with clean engine oil before installing it.

• When installing the injector valve, make sure there is no cleaning product or oil in the holes in the cylinder head.

- Using the included (T10133/4) thoroughly clean the high-pressure fuel injector bores in the cylinder head before installing the fuel injectors.






- Press the fuel injector by hand into the bore in the cylinder head (free of oil and grease) until it stops. Make sure the fuel injectors are positioned correctly in cylinder head.

• The fuel injector must not be difficult to install. If necessary, wait as the combustion chamber seal continues to pull itself together.

• Check fuel injectors for correct seating and installation position in cylinder head.

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






- Further installation is in the reverse sequence to removal.

Important: Always observe the following points.

• Coat the O-rings for the fuel injectors with clean engine oil so they are easier to guide into the fuel rail.

• Replace all seals.

• The fuel rail should be placed on the fuel injectors and pressed on evenly.

• Install intake manifold with fuel rail. Refer to => [ Intake Manifold ] Intake Manifold.
