The four basic manuals are:
ORD 9 SNL G-741
List of All Service Parts of Truck, Cargo, 3/4-Ton, 4x4, M37, et al
TM 9-8031-2
Power Train, Body, and Frame for 3/4-Ton 4x4 Cargo Truck M37, et al
TM 9-1840A
Ordnance Maintenance Engine Dodge Model T245 and Clutch Borg and Beck Model 11828
TM 9-8030
Operation and Organizational Maintenance 3/4-Ton 4x4 Cargo Truck M37, et al
I much prefer the paper versions over the CD ones, as the CD scans are missing or have garbled text. For the paper copies, I like the ones sold by Canham & Sons Books (
http://www.themanualguys.com): he prints them on standard 8-1/2 x 11 paper, and then will either three-hole punch or comb bind them. Both work well for use out in the shop.
Other manuals of interest:
TM 9-1826A
Ordnance Maintenance Carter Carburetors (includes the ETW1 and the governor)
TM 9-2520-232-35
New Process NP420 Transmission (If you have a truck with the later NP420 transmission)
Dodge Service, Power Wagon Advertiser,

There are lots of other publications that will have info relevant to the G-741 series, depending on what your interests, problems, or needs are. Some of them are listed here:

This forum is one of the best sources of info. Using the search function (and being creative with the search terms) will unearth a great deal of knowledge and experience, especially from some of the professionals who post here. I've been doing that since I joined, saving and printing out the applicable topics that apply to whatever I'm working on, and now have six large binders full of information to supplement (or substitute for) the original military manuals.
