Injector removal

thankyou i already have one of those manuals but unfortunately they arnt exactly comprehensive .. the fully comprehensive manuals avalable from Phil hunt at Tamworth are over $700 :-X

Sounds like it is similar to Bosch MAN and Mercedes injectors. The threaded hole for the injector has what looks like a half drilled hole slightly off set from the centreline of the head.

The Germans did this to allow all the dirt and water to get in behind the retaining nut and sieze the injector real well in the head!

However the hole acts as a locator for the injector, which has a little dick on the injector body to make sure the nozzle aligns properly and sits in the right spot to dump the fuel all over the piston and make the fire in there real hot.

Shove some rust loosening stuff or diesel down around the injector and use a slide hammer (if you have the room above it) Make a fitting for your slide hammer out of an injector nut and a couple of good hits will see it sailing through the air before crashing on the ground beside the engine.

A less spectacular way is to use an appropriate spanner over the flats on the top of the injector to try, twist and turn (albeit a miniscule amount because it has the dick on it) to loosen it. This will keep you busy for hours of fun , so invite some friends around for an injector loosening party, they'll talk about this one for years.

yes that does make sense ..with the locator dick ..(which at the moment is a real dick!) i mite give the engine a 5 second startup tomorrow to see if it dislodges if not a slide hammer as you recommended might see the injector airborne

If you are going to fire her up to loosen em make sure you keep the retaining nuts on em but a couple of threads loose, so they don't send themselves like german hand grenades through the air seeking anything with glass in it.
Stops the injector lines being bent and then only useful for gate post twitchin or lynch pin replacement too.
