I have a 10mm TDI pump and an AAZ pump and a GTD pump.
Is it worth fitting the 10mm head to either? And if so which one?
I would need to have two useable pumps at the end.

No, unless you use an AAZ camplate and fabricate a custom internal throttle lever system.

you can fit the head without any modifications if you don't put the tdi camplate.
Also, only the AAZ pump from 1995 and over will have camplate that fit 10mm tdi head.
It is worth it... more power for sure!

Good info guys - thanks!

It's a 95 pump - is there anyway I can tell from it's part number if it is compatible?

Yes, those # will work
0 460 494 362
0 460 494 373
there might be other #, give me your pump # and I'll check if it is not one of the above.

I thought the fuel quantity slot on the plunger is located/shaped differently between the tdi and idi?

Will the fuel control collar on a GTD or AAZ pump fit over a TDI 10mm pump? If not, you have a problem, since that collar controls when the injection stops.

everything will fit if you don't use the tdi camplate. If you use the camplate, then u need to modify the levers inside the pump.
You can the K and KF settings if you use another head.
I've run an AAZ with a tdi 10mm head for 2 years!

So to summarize this you would need;
tdi collar
tdi plunger
tdi head
tdi return springs?
And it will fit in the aaz pump no problem, as easy as that?

yes.... you can use 1.9td spring and shims.
use:
hydraulic head... that's it. The head is only complete if you use the collar, plunger and head. You can't mix the pieces. Even between to 10mm head, you can't interchange the collar or plunger.
You might want to install a 1.6td regulator and adjust it so that timing advance will be ok for all RPM.

Why cant you interchange between 2 10mm plungers and collars?
Are they produced in such a way that they are matched to each other?
What might happen if you used a collar from one 10mm pump and the plunger from another 10mm pump?

They are matched pairs. It's something like a 2 micron difference between the 3 pieces. You might get lucky, but more often it will sieze, or not produce enough pressure.

So I could slap a 10mm TDI head on to a 1.6TD pump? Should I use the 1.6 camplate or an AAZ camplate? So why are people so hung up on trying to find elusive puegeot/4BT heads when they can just put a big tdi head on?
