where can i get an injector socket 1.9AAZ

[James8485]

i have a set of 1.6 injectors with the merc nozzles in them and am getting itchy to swap out those old 1.9AAZ injectors as they're starting to stick alittle and have over 340 000 on them.

now that its getting alittle warmer out there im ready to tackle the project.

i know i need a 26 mm socket but i cant find one anywhere. well i can find them but there not deep enough. princess auto had one but it was like 1/2 short.

where can i get a socket thats going to work anyone got one i could borrow (ill pay shipping) or buy for that matter?
kinda wanted to do this ASAP!!!!!!!

have heard this should put alittle more boost in my aaz! i am running a K24 turbo on it so should be able to handle the extra fuel!

please let me know

i was told on here to use 1-1/16, it worked beautifully, go grab one from canadian tire $9.99 for 1/2 inch drive deep socket, the points are rounded to fit the barbs on the injectors.

i took a normal shallow socket and cut it in half, then i welded a piece of pipe in between the two. so its about 4" long. its changed so many injectors and never let me down.

Exactly what I did. Works great!

sears.. they have a socket their.. the nipples for the return need to be pinched up abit

Two hints:

- the AAZ injectors are wider still than the 1.6 injectors so be careful when test-fitting sockets... breaking off the barbs is a 1-way trip.

- the AAZ injectors are taller than the 1.6 injectors, so you're in for some bending of your hard lines if you try to retrofit 1.6 injectors

OK, 1 more thought:

- if you do some reading on Mercs injectors you'll find that some like 'em and some think they're a bad idea because they're not designed for the shape of the VW pre-combustion chamber.  You should be able to find a thread where Giles specifically does NOT recommend them, for instance, and several others that discuss the probability that the stock nozzles are fine for lots more power than stock.

I mention this only so that you're clear in your own mind you want to run 'em before you go bending your hard lines up.

i know i need a 26 mm socket

 :? er, I thought they were 27mm? or is senility claiming my memory?
It will fit the nut that holds the oil cooler to the oil filter flange when the inevitable happens, so that will be a bonus. :wink:

True, and true... good catches !!

As Vince noted, the AAZ injectors are wider than the 1.6, so any old        1 1/16" or 27 mm (same size) socket won't work...the return barbs get in the way.  The socket will seem too shallow simply because the barbs are hitting the thicker upper portion of it.  I purchased a 27 mm deep chrome Craftsman socket.  I then took my die grinder with an extension on it and carbide bit and ground out the upper portion of the socket to accomodate the barbs.  I like the idea of cutting the socket and welding a piece of pipe in the middle...that would work too as long as the inner diameter of the pipe cleared the barbs.

it clears the 1.6 barbs by a mile, so i bet AAZ injectors would not be a problem. its kinda funny, all my "special vw tools" are just adaptations of other tools, or some i fab up from scratch. hell with paying 3 prices for vw tools.

all my reading on this forum has lead me to believe that mercedes nozzles hurt performance more than help it.

[blackdogvan]

FWIW I saw in some guys sig on a mercedes diesel forum braggin he had AAZ injectors... The grass is always greener.

I use a Wright socket , the flutes inside the socket go all the way down to accomodate  the return nipples. bought it at KMS tools for 6.99 a while ago. Cheers Dan

I have a 'Craftsman' 27mm deep socket, #V44449, purchased about 30 years ago, to work on my M-B 220D, that must have been made for the purpose. It is 12 point, and the broaching runs full depth (2-1/2").

[Hey]

Go to sears, buy a 27mm long box (stainless steal looking one)

Also buy a tungstene base metal bit for a dremel since you will need to make the tool a little bit "longer"... you will see when you try an injector.
