7 mm
7 mm
5.5 and 7, 7.5mm refer to the diameter of the plunger inside the element of the injection pump. There is one for each cylinder of the M.B. engine. Some other makes used different arrangements
If upgrading, this must be done by a Proper Injection-shop, Its not summit you can do yourself...
This is what an element looks like--

Allot of hp. Its not a science or a given number/formula of how much 10mm elements will yield hp. But It does yield a specific flow amount.
From there its all a matter of multiple parameters (turbo, motor, etc...)
(12-01-2010, 12:10 PM)AMG Thanks! But in what a difference between 7мм and 5.5мм?

For these plungers, if all 8mm stroke were used (it can't be) this is the plunger volume per bore size.
5.5mm=0.190ccm
6mm=0.226ccm
7mm=0.307ccm
10mm=0.628ccm
It has a bigger bore!

Stroke can't change without regrinding the cam or increasing injection duration.
These pumps use a constant start, variable end delivery method; The more fuel you inject the longer the effective stroke is. Thats why the 5.5mm pumps cause high EGTs when turned up far beyond stock.
Larger bore plungers bring the injection duration back into a safe time window. Or in the case of the non-turbo projects, inject the same amount of fuel sooner so the fuel has more time to burn.
10mm element can be used m but with p type you can use only 8mm,
but it s ok because those modern engin gan give a lot more power than those stone age iron engines with small turbos and 10mm elements
ОК... What to make 7мм it would be necessary to lift plunger? Then the chamber plunger will increase.... Or it absolutely other detail? I wish to make it itself, but I to understand that it can not is necessary to make with old ..... Means it is necessary to chisel a plunger to 0.307ccm and to replace the bucket on 7mm?
From what I gather, you want to 'make' these yourself...?
This is NOT Possible.....
Elements are Mega Precision Parts, with surface finish better than 0.1uM You Cant make them in your average well equipped Machine-shop, let alone your garden-shed!
You must Buy the required Size, Then they must be fitted--Which you also Cannot do unless you have PROPER facilities to do so.--Like a Diesel-Injection Test-Bench and or full injection shop....
So, You BUY the parts, and get Injection-place to fit and set them up in your pump....
Waste of your time to even try to make these yourself.....
(12-02-2010, 03:27 PM)AMG ok....BOSCH service can do ? Also what such ALDA? How it is deciphered on letters?

Just give diesel pump specialist do the job.
You can find those a lot in Europe. Best can find in Finland

Yes, Bosch agents can fit.
But They wont want to!( No Test-Plans for what you want, they cant set it--too much trouble for average place) There are guys that will do this though, not a real problem, send your pump to Germany, there is a guy who can do the whole job, supply and fit.
ALDA is device for increasing fuel delivery with rising turbo boost-pressure. Not all pumps have this, Only pumps from Turbo engines.
What Car and Engine do you have...?
What Pump have you got on it...?
What modifications have you done already....?

Hi. If there in Viro dont have pump shop who install bigger elements you should ask at Mynä-Diesel in Finland what it would cost and when they can do it.

Hey AMG, what transmission do you have with the 603 engine. I have a few questions for you and how you did that swap. I too have a 603 Turbo in my w201, and would like to get some information from you also??
George3soccer
usual automat with short shaft from 2.5 diesel w124, but it will be better to put in transmission (with short shaft) from 3.0 diesel, but then you need to shorten the cardan.
there is a link, about how was constructed my car, with photoreport. (sorry, there is everything on russian language) there is a link, about how was constructed my car, with photoreport. (sorry, there is everything on russian language)
Very nice swap, what kind of engine mounts are you using.

Then Dont Waste Your Money on a 7mm Pump modification for larger elements for This Engine....
Its NOT Worth It!
You Need Better (Turbo) Engine to make 7mm elements Work Properly....
IF you fit 7mm to your Non Turbo engine, All you'll make is--Lots Of SMOKE! and not much power
