Anybody taken MAN injectors out? Most people are talking about collars with retaining bolts into the block that you remove after the fuel lines come off. These look more like a collar ring around the injector that threads into the block that needs a spanner of some sort.

Could be a bolt down clamp or collar. Usually it's a hex, but knowing the Germans it could require a special tool. Post a pic and I'm sure we can figure it out.
MAN injectors are frequently frozen in the head because their owners are proud and wash the engines. No kidding. That's caused more heartburn than you can imagine.
It appears that the injector is held down to the head with a threaded collar ring that looks like a castle nut on top. So I would think that a special socket with spanner nubs slides over the injector to engage the retaining ring and unscrews it while you hold the injector body in place at the top with a wrench on the two flats just under the fuel line threads. Simple enough, but then I read the instructions in the service manual and it sounds more complicated than that:
Remove pressure screw from the fuel injector using a pin spanner
For this purpose use a ring spanner with a fixing screw
Where injection nozzles are more accessible, screw inertia extractor on to nozzle holder and knock out nozzle holder
Take out injector and injector seal.
What does all this sound like to you? Whats going on with that two wrench set up?
Thanks,
George

I have ordered this specialty tool set that I hope is the correct "socket" for injector removal.
