Thread: Adjusting TD5 injectors

Is it so that i a have to turn the engine so that an injector is fully open and then schrew the adjustment screw in untill it not goes further and then one turn back? Yes this is correct The cam lobe should be at full lift. i.e plunger fully depressed.

Please could someone help me out.
Thanks a lot in advance

Cheers

correct your setting the bump clearance.

this stops the mechanical action of the cam trying to compress metal through metal which doesnt happen and when it tries to happen very very bad things take place.

Thanks a lot four your great help

One more thing.

Do i need to remove the diesel fuel from the cilinders after taking an injector out? (the diesel from the common rail runs into the cilinder after removing the inj.)

depeindin on how much got in there yes other wise you'll contaminate the oil when it leaks down at best or hydraulic the engine when it tries to start at worst.

YES!!!!

Remove the fuel pump fuse and crank the engine without the injectors in BRIEFLY to pump out the diesel .
As Dave said, hydraulic lock WILL happen even with a small amount of diesel in the cylinders

Job finished.
Engine runs fine and does start very good.

Thanks for all the info which helped me a lot.

Bad news,
Still leaking diesel in the sump.
Can injectors leak between the solenoid and the injector. The connection with the two allen bolts.

What is the torque for the two bolts on the injector.

One last question: Is there a link where the working of the injector is explained well?

Yes they can leak, BUT also there can be a fissure in the well where the injectors are sitting, you may have to remove them again and take a careful look at the sides of the well for cracks.
