Many thanks to OM616 for putting his time and effort into putting together 99%+ of the information in this document.
Nice.....
But, Not enough about the 'M' pump specifically, for me!
We dont have the MW here at all as far as I know--Never seen one on M.B anyway!
Well, the basics should swap over since it's mostly the governor in the doc right now.
If anyone wants to add to the doc, let me know and I'll add you to the edit list.

That is a great explanation of how the pump internals work! Turns out I was right, I didn't know crap about the guts of a pump. LOL I had gotten lucky when I pulled the rack limiter out of my MW and felt an increase. Also explains why some folks here didn't feel anything. Thank you for your effort on this!!
Excellent document. Thank you very much OM616.
It's all in there.
Start with a known working pump, document what you do, and follow the guidelines.

I'll have to read it a few more times then.
Edit: on further thought and reading, what i gather is that several adjustments are interdependent.
That would worry me if I were to start messing with any of the settings.
So I would think there's a specific or recommended order to adjustment.
Should I assume that that procedure is covered in the official Bosch manual and this doc is supplemental to the official manual?
It's perfectly fair if this is the case but it should probably be stated explicitly -- something like a "how to use this doc" statement. Especially since the instructions we had a while back for RL removal were sort of a f*** the manual kind of deal.
Overall I'm pretty stoked on the information there.

since a lot of this revolves around the "rack" can anyone post a pic of one? ive searched a while on google and not had good luck.
i may have seen it but not known what it was since this is my first time playing with IP's. but im tryin!!! lol.
The actual rack is hard to see without taking the ip apart. Thermo king diesels(made by izusu) Have a cover plate that you can see the rack itself. It looks like rack and pinion steering gears. What you most likely want to see is the rack limiter, and it adjustment. There is a good picture of it in one of the recent posts on this forum.
That is an awesome Read OM616. THANK YOU. It makes perfect sense.
One of the important things that stood out to me is that it seem thats TC and Max rpm should be, I would say, adjusted equally. Return to Idle seems easy enough to achieve
.... Now to put the rack limiter back in ....
Oh! Speaking of that, You had mentioned briefly on possibility of a SLIGHT rack limiter adjustment being made, but I did not see anything about it later. Is it something that will be added later?
Please understand I do not mean to push you here, Just trying to ask some intelligent questions. Give me some time, I will explore myself on my virgin (Rack limiter less) pump
Don't yell at me!
In this case, "slight adjustment" means you can adjust it to let the rack travel slightly further, and it should work.
We also need some back cover and side cover shots if anyone has their IP apart.
Give me a couple days, I will post some

(08-27-2011, 10:01 PM)Captain America Why cant his pic be up? "permission is granted to copy and/or distribute as long as this picture is not altered"Because I don't want any more headaches. Yours is going into the IP thread

Can someone please tell me how they broke the locking ring loose on the torque control? Last time i unsuccesfully tried, it was i giant PIA, and i gave up and everything back together because i had to have the car the next day
(09-01-2011, 01:25 PM)winmutt IIRC I ground a socket down to fit.

Thanks for the info OM616
Do you approve of the labeling on the pump picture?
thank you very much om616. I appreciate the document you typed up and all the information you provide. I dont think i would even come close to understanding a mw pump without your MW Theory [/i]

I just went to check this out and it seems to require a Google account which I don't have...
Works for me without logging in
Do you have G-mail or any google related sign-in's? Maybe my youtube log in would work...
I do but not logged into it when I load the page. PM me your email address
For grins, I just typed in my usual forum password and it let me in. I must have set something up with Google in the past. Got the document now, thanks to OM616 for the time and effort put into this!
HELP / INFO please
Will a pump from a 300GD work on the OM 617.952 engine. Also, I was told by the seller that the "M" Pump did not have an ALDA. Is that true. Below is the pump's info. Will this work for my 1985 300D Turbo ?
Please let me know. I am getting ready to buy myself an "M" pump finally.
Thanks in advance.

300GD is almost certainly going to be om617.91x and would not have an alda. I would also imagine that the GD is tuned for torque. If you are planning on upgrading(rebuild and elements) this then you are gtg, otherwise pass.
Do you need a new pump?
Hey,
I am looking for a "M" Pump for a rebuild ... SUPER PERFORMANCE BUT also OK for everyday driver. So is this OK ? No ALDA ? So I guess I will be getting rid of some vacuum elements and lines. New Pump ? You have one for sale ? Thanks
awesome write up om616
, ill be re-reading it a few times . if i get most of the fine balance act of tuning it ill be happy .it seems like for every turn in or out you make you have to mirror/negative the adjustment on the other end of the spring , is the ALDA and shutoff valve the only pressure actuated fuel delivery function on these pumps? i have an auto so i have the trans functions . having trouble finding a good vacume thread on here, for tuning my tranny , before i start tinkering with pump etc ?
