Re: CCKW REALITY CHECK

Many of the CCKWs, no matter when delivered were found with Die Cast Carburetors installed as their years in the Army rolled by. All that is necessary for switching carburetor styles is to use a matching air cleaner for the type.
During the 60s Zenith manufactured a Die Cast Adaptor with square flange that clamps to the CCKW Die Cast Carburetor and allowed use of the late style air cleaner associated with the Cast Iron Carburetor. Many of the European returns are thus set up.
The Die Cast Carburetor is the way to go and NOS are available in limited quantities.
ACTUALLY the die cast carb adapter for late model air cleaners was available in 1944. There is a GM SB that clearly shows it and also gives the PNs.
The die cast carb and top heavy air cleaner were very prone to falling off and even when the mod to add the block to air cleaner support was added it was known that even this was a poor patch. The new support not only fully supported the carb, but the new air cleaner bolted to it.
Please reference GMC Bulletin G-98 for the pictures.. I'll post them when I get them scanned in.
Zenith model 28AV11 PN 9778 are not hard to find. NOS is fake term.... used to try and separate people from their money.
I would also like to know how CCKWs were equipped with superseded parts. Why were trucks in 1945 still not using Series I hydrovacs? Because they were superseded by the Series II and III.
