The GMC CCKW

It was found that there was a problem with the factory location of the reflector on the wood cargo body tailgate. Some of the reflectors were not installed in the approved location, and resulted in breakage when the tailgate is lowered.
The Ordnance Field Service Bulletin 10-1000-6 dated 10 March 1943 directs that the center of the two bolt holes of the reflector be located 5" up from the bottom edge of the tailgate.

Another quality tidbit from the great dufflebag of CCKW history resulting from wonderful time with good 'ol Uncle Sam 46 years ago. Seems like it was just yesterday.
Dufflebag? What a funny name.

It says to repeat the operation on the others side of the tailgate.

Vehicles affected are:
2 1/2 Ton 6X6 GMC STUDEBAKER
1 1/2 Ton 4X4 CHEVROLET
6 Ton 6X6 Corbett, White
4 Ton 6X6 DIAMOND T
4 Ton 6X6 Poonton, FWD IHC
7 1/2 Ton 6X6 MACK

It appears that the misslocation on any tailgate could result in breakage of the reflectors. These are words of wisdom to those that would buy a reproduction tailgate and install it on their truck.

The problem was with the wood bodied tailgates only, reflector location is not a problem on any of the metal tailgates used on the WWII Cargo Body.

Please explaine why? Did the wooden tail gate mount differently than the metal ones?

The Steel Tailgate is 12 Ga Steel, less than 1/8" thick, the wood tailgate is somewhere between 1" and 2" thick. The geometry of the hinge and extra thickness of the wood will cause the reflectors tocontact the #7 Cross Sill on the 1108" Cargo Body,and the #8 Cross sill on the 144" Cargo Body. This is stuff I learned back in the 50s-60s and have not forgotten. Some of the manufacturers of the Wood Body had installed the reflectors in the wrong location and they were being damaged with use. A Service Bulletin was issued to correct the problem. What is good about being in the hobby is being able to relate to the TMs and Army Bulletins in order to maintain my own CCKW. That's what Honor Grads are all about, and 46 years later I can still strut my stuff.

Ohhhh, I missed that part of the Honor grad. Sorry, and thanks for the information. I will keep it in mind. It is nice to be able to Strutt Your stuff.

I prefer "quicktime" @ 120 steps per minute, the same as the put,put,put of a well tuned 270 at the pace of a parade. My truck blows OD smoke rings and General Motors is my Chief of Staff. I have it made.
