Out of curiosity : can't one just fit the complete head with springs and camplate into any mTDI pump ?

Also, 1.9td regulator wont work with 11mm pump!!

 
Tell me why?
Did the pressure in the pump is too low in low rpms?
I have 1.9td regulator and at cold engine i have wite smoke and i looks like pressure was to low. when engine was warm the smoke disappear.

That's what I'd do for a 5-cyl mTDI.  I've never taken apart a 5 cyl pump, but I imagine that you'd also need to use the roller cage and rollers (are there 5 rollers?).  That might cause some added complication as the electronic pumps don't have the cutout in the roller cage to accommodate the governor.  Some machine work there would likely be in order.

only 3 rollers in a 5 cyl Audi pump..

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

I am using 1.9td regulator and advance pistons with stock shims with 11mm pump and am quite happy with it.  I wish I hadn't deleted the cold start lever though.

by this day i think 1.9td regultor won;t work with 11mm. I must say that i think pressure in the pump is to low and car have white smoke on cold engine.
410 have that regulator and he is happy, but i try everything and white smoke don;t dissapear( this is a lot of smoke). But something about 3,5 bar white smoke is weakness and i put one pad into regulator, there is ok but timing don;t go to the end of regulator. rpm' goes something about 500 lower than before but engine works queitly.

Nice to see you still check the site Hey.  My pump is still going strong too with over 40,000km on it.

I build a 2.5 TDI in my Audi 100 from 1977 and I also had the issue with the rollers and I solved it like this:




Original 2.5TDI pump


Comparison between the roller houses



New one with 4 rollers instead of 3.


New pumphouse.

I've been driving for a good 10.000km with this pump and a friend of mine is driving a NK offroad car (paris dakar type of vehicle) and we also build in a 2.5 R5 TDI engine with the same pump. With DSS ultime nozzles a VNT22 he has got more than 300HP and almost 650Nm on all 4 the wheels. When I get the dyno sheet I will post it.

I just picked up an aaz pump with an adjustable pulley thinking that it might have a 20mm shaft.  Sadly it is only a 17mm shaft.
