There's a ton of stuff to absorb when you first get involved with these trucks and probably something that gets overlooked quite often is the TMs. The TMs have a wide range of information in them from troubleshooting to theory of operation to maintenance proceedures to parts lists and all of it will serve you well if you take the time to get familiar with them. The lowest level manual is the basic Operators Manual, TM 9 2320-280-10.
TM 9 designates it as a technical manual and the 9 generally means motor vehicle related. The 2320 is the stock class meaning truck and the 280 designates it as a HMMWV manual. Any time you see a manual with a TM 9 2320-280-xx it's directly related to the HMMWV.
The suffix tells you purpose of the manual and it's skill level. A -20 manual is the manual for troubleshooting and basic basic reapirs at the unit level. This means it can be done at the local level. The addition of suffic - numbers will indicate the volume of the manual, so a TM 9 2320-20-2 would be the second manual in the Direct Support series. Typical suffix's seen are -10, -20, -20-1, -20-2, -20-3, -24, -24P, -30, -30-1, -30-2, and if you see -40 manual usually this is a depot level manual that goes into some real depth of repair. The "P" on the end of a manual usually designates that it's a parts manual.
In the front of the manual on pages 1-5 there's a description of how to read and understand these manuals and that's where your going to find your Used On Code, (UOC). This tells you which vehicles the particular part number is applicable to. See the chart below for HMMWV UOCs
Keep in mind that there are TMs for almost every part of the HMMWV that will have slightly different numbers. For instance a TM 9 2320-237-20 manual is for the engines. There are manuals for the Transmissions, Brakes, Differentials, Maintenance Work Orders, Alternators, and anything else that can take some time to learn but keep trying and it'll come eventually.
BTW: Here's where you can get them for free: https://www.nsncenter.com/library/hmmwv
Hope this helps at least a little bit.
