Introduction to Line Setting Ticket decoding.

This short primer will reveal the deep dark secrets of the decoding of the infamous Line Setting Ticket. It is not
very difficult to do it, but when you see that build sheet with all those confusing numbers, well, need I say more?
Let's get to it...

The whole build system is arranged in parts groups which is the highest level in the hierarchy. Actually this is
a smart system, much better than arranging parts lists after model and year as many other manufacturers do.
The parts groups are:

The code numbers on the LST (Line Setting Ticket) consist of nine digits. There are some exceptions to this
like if the truck was ordered with special equipment, and if that is the case the code numbers will be preceeded
with "SN", "SE", or "SA". In some cases there are more than nine digits, but the general system is based on nine
digits.

Finding part numbers.

So, what do these nine digits tell you? They tell a lot, in fact, they tell the whole story. Let's take an example to
make things a little clearer on the subject.
Let's assume you need a left rear spring mounting bracket for your 1100A. You look at your LST and find out
that the code for the rear spring is 03205.0001. This is a typical nine digit code number and it is interpreted like this:

Now you pick up your Master Parts Catalog for your truck, in this case it would be the MT-118, and turn to
the index of group 03, Chassie and Springs. Here you find a listing for a 1100A truck, and a little further
down you find a listing for "rear", with two entries, standard and with auxillary spring along with the code
03205. Follow that line to the right and you see that you should go look at figure 03-7. Looking at this
figure you'll see that the bracket you want has key number 1, and in the parts list you get the assigned
part number. In this case the part number is 236 584 R1.
That wasn't very hard, was it?

Miscellaneous.

There are a couple of quirks here and there in the parts books though, some parts are available in a kit,
some parts are chassie number dependent, and some parts are shown in a different figure in special
cases like Right Hand Drive vehicles, or exported vehicles.

Another place where it gets a bit complicated is group 06, Propeller Shafts. Here you can read the
placement and length of the drive shaft, as well as manufacturer and yoke type and placement from
the code number. Each shaft on a particular vehicle has a location number and a 10 digit production number.
In the case of your C1100 4X2 which only has 2 shafts, location 1 is the shaft off the back of the
transmission which has the center bearing on it and location 2 is the shaft to the rear axle. If you have
your 10 digit shaft production numbers, you can determine all the components in them and their lengths.
Here is a basic breakdown of IH 10 digit shaft code:

Sadly I don't have the charts needed to decode this stuff handy, and they are not present in the MT
parts catalogs, so this info will have to wait until I can get them.
