The LO I have in my TM clearly shows the 6V batter on the inner frame rail, just to the right of the tranny (P. 0-106). The battery tray also looks *very* civilian (P. 2-1).

The 'later' outside the frame rail, 3 part battery box is on page 12-1.

How late into 42 was the early type battery tray used?

Paul,

There is a very good posting on G503 forums on the differences between Y, Z and N series trucks. http://g503.com/forums/viewtopic.php?f=25&t=214745

The change you mention (battery inside the frame rails, to outside) is just one of a number of changes that seem to have occurred when the military issued a new contract of the N series of trucks. The early maintenance manuals that I have seem to be a product of General Motors, not US Army Ordnance, and also have no TM number or publication date. The only reference I found in the manual that helps to pin point its publication date is an update sticker, replacing part of the text under the "Aux. Equipment" section of the manual. The text originally said to contact Gar-Wood Industries in Detroit, MI, but the sticker says to source parts as indicated in the G-4112 parts manual. The G-4112 trucks were limited to 'Y' series trucks, and one N series (NZ, which was a "Crash" truck, built on a 'ZH' dumper chassis).

The copy of the TM10-1127 (a 1942 manual) does not mention the Army at all (unless I am missing the cover page?) And I did get a copy of the post war GM post war maint manual.

Thanks for the link.

Paul,

The cover (which you mentioned you're missing) says "Built for UNITED STATES ARMY" on the outside front, and on the front inside cover, there is a large text box which begins:

TM 10-1127
Change No.1

WAR DEPARTMENT
...

and ends with:

"By order of the Secretary of War:
G.C. MARSHALL
Chief of Staff"

Of course there should also be an illustration of the Serial Number and Load Data plate, which mentions the QUARTERMASTER CORPS. and the model is listed as G 7116. The lube chart still shows the battery inboard, while the cabs shots show the military style gauges.

Now that I think about it, my earliest manuals show a similar Serial number and Load Data plate, with the model noted as G 4112. The cab shots show civilian style gauges.

Interestingly, both cab shots show a similar arrangement of data plates with two on the glove box door, and the rest on the windshield header panel. They both also show keyed ignition switches.

By Dec 1943, the TM 9-805 shows all of the data plates on the header panel, and the ignition switch is a toggle switch, not keyed.

The TM10-1501 (1941) covering CCKWs had much more specific information regarding its Army contract information. Again, unless I am simply missing those pages. Frame SNs, Registration No's, Contract No's, Qty per order, etc.

Since there were so many Chevy models, were the manuals kept 'Generic'?

The manual I have starts as the page with 'FOREWARD' in the middle, centered, with two paragraphs under it.

Most of my manuals fit that description. The March 1, 1942 TM 10-1127 (Change No.1) cover lists a number of models (8 or more) and 5 contracts covered by the manual.

Which model number is shown on the Serial number and Load Dataplate in your manual?

Here's the data plate from page O-4

I am pretty sure that the manual you have is this one...
