TM Question

[Vapor Trail]

I was trying to figure out the TM situation in the thread above but they closed it for comment. I went to a different forum here that said I have insufficient credentials so here we go.

I bought the printed version of these three for my 2004 M1123 but found that the information I was looking for was not in them.

TM 9-2320-280-20-3
TM 9-2320-280-24P2
TM 9-2320-280-24P1

I'm looking for what the military uses to actually do the maintenance procedures with. Would that be

TM 9-2320-387-24-1
TM 9-2320-387-24-2

This is the site I go to for most TMs. The ones you're looking for might be in the left column, the 3rd-5th items.

HMMWV - High-Mobility Military Wheeled Vehicle (HUMVEE)

The HMMWV is a 4x4 All-Terrain Military Vehicle introduced by the US Army in 1984 also know as Humvee. With over 300,000 units produced and in active service with 70+ countries as well as in civilian use.

OK, I think I got it figured out, Thank you. I needed two more for the complete set I think and I got them from Amazon too. The 387 ones were for a different model

TM 9-2320-280-20-1
TM 9-2320-280-20-2

So the last few digits are what separate them.
the -10 is operator manual
the -20 are maintenance manuals. For the M1123 there are three manuals total, so will end in 020-1,-20-2, -20-3
The -24P are parts manuals
The -30 is depot level maintenance, so not what you would normally see done by the regular mechanics

Yup, the 387 is for the newer ECV/REV trucks. Some info is the same, but some of the specifics are different.

The "Closed For Comments" in the TM Section is just to cut down on opinions about the Technical Manuals. Once posted here and the upload is "Closed" that confirms that we have a known good book. AND that it is confirmed to be Approved for public release (distribution).


Lifted from Mike:

Well, some others have delved into this subject before, so we probably ought to look at what they have to say. First the current Army numbering scheme can be found at https://radionerds.com/index.php/TM_Numbering_Specification and a writeup I found elsewhere says "

Early TM’s have numbers like “TM 9-2300”. The first number being the subject or branch of the Army. Number “9” means that it is an Ordnance Branch manual. The second series of numbers referring to the particular manual.

The many later TM’s, concerned with single pieces of equipment, especially Ordnance equipment, were numbered like “TM 9-1005-223-12”. The first number refers to the branch. The number “9” means that it is an Ordnance branch document. The second series of numbers refer to the subject type. The third series refers to the particular piece of equipment or subject.

The four series on numbers refer to the level of maintenance which the manual is concerned with. With “10-12” being operator and organizational maintenance level, and with higher numbers concerned with a higher level, 20’s being direct support, 30’s being general support. ".

Other four digits are the Federal Supply Code, which can be found at http://everyspec.com/FSC-CODE/ which are further broken down for some categories (usually designated by having a dash and a number for the sub-categories).

Like I said, it's all above my pay grade!

Thank you, that's good to know. Maybe I do need the 30's because my vehicle is completely stripped to frame right now. I was looking for all the technical info about hub rebuilds and brake caliper rebuilds and such
