This link is to all of the manuals.
The main things to remember when looking through the manuals are that the M1123 is an "A2" truck. It's equivalent to an M998A2 with a few modifications that the Marine Corps wanted, and thus got it's own designation.
example, see the header:
Another thing to remember is when going through the parts manual (the TMs with "-P" at the end of it) is that the UOC (Use On Code) for the M1123 is "NNN"
This means when you are looking at parts, and find the correct diagram, then part number and description, if it's specific to a certain model or models, there will be a UOC
Example, look at the red circles:
If there is no UOC listed, then the part is universal to every model of HMMWV
And yet another thing to pay attention to is that there are two different serpentine belt configurations, usually listed as "before Litens" and "after Litens" for parts. In the manuals it's also commonly listed as "pre 196900 serial number" and "post 196900 serial number" or similar description. Then to make it worse is sometimes a post 196900 serial number engine gets put in a truck with the pre 196900 serial number truck. Easiest way to tell is if the power steering pump reservoir is built into the pump assembly, or if the reservoir is remote. Extremely easy to tell them apart if you know what either of the power steering pump reservoirs looks like. The first example above is power steering pump with built in reservoir, and the example below is the one with remote reservoir.
