G'mornin',
I must apologize if you thought that I meant that this little book had vacuum diagrams.......it dosen't.......it has tables that tell you what the color code of the vacuum hoses is.....

example.....
Central Locking System
Color Code of Vacuum Lines
Model................................................107 3rd Version
123 2nd Version
Suction line from engine
to 1st destributor grey

Suction line from destributor
to vacuum storage tank yellow-grey

and so forth.......................

This little book has a wealth of info, but few illustrations, and no pictures!! Just text.....
some of the few illustrations are related to engine v-belt routings, torque sequence diagrams, axel position and frame measurements, and air gaps of various body panels

It can be ordered online from http://www.mbusa.com/heritage/index.do
just mouse over the "Classic Center" tab....and select "Technical Literature"
You will get a page where you can identify your year and model of car, chassis designation, engine designation, and it will turn up all the literature that MB offers for that particular model........

I have also purchased the "Model 123 Service Library" offered only on CD....
it contains.....Literature pertaining to the following Models from '77-'85
230, 240D, 280E, 280CE, 300D, 300CD, 300TD, 300D-T, 300CD-T, 300TD-T

For an '85 300D-T...the only section that I have opened......
Engine Manual
Electrical Troubleshooting Manual
Maintenance Manual
Owners Manual
Climate Control Manual
Chassis and Body Manual

it appears that these are the complete manuals that sell for BIG$$$$$ on e-Bay....but in .pdf format.....

UNFORTUNATELY it is unsearchable.......you have to go to each individual manual, read the index and page thru as you would in a book......in order to locate whatever info you desire......if MB printed it, it's in here someplace!!!

This little book that I refer to in this thread is...as I've stated before....a Service Tech's Toolbox Reference Book......supplimentary information, for the person who is actually turning the wrenches......like the Vacuum Line Color Codes......or Hydropneumatic Suspension Testing Values.....

I apologize if I have peaked anyones hopes on an easy to find list of diagrams, however as I am a retired Engineer, I find the little "Technical Data Passenger Cars" book to be very informative, and quite interesting.......if you are considering purchasing parts to transplant a 5 speed manual transmission into a 300D-T......it lists the correct part numbers for which flywheels fit which engines, and which pressure plates fit which flywheels.....and which clutch friction discs fit which transmission spline.......and so forth.....

Whew...that kinda got a bit long winded.....
