Danish Army
Specific: The GMC CCKW-353 was
delivered as a part of the American aid program (MDAP) between 1951 - 1955. Typical role
for the GMC was transportation of cargo and personnel,
and workshop- or spare parts-van. Also used as a fuel
truck.
Delivered with short wheel base (GMC
CCKW-352 (85
kb)) as artillery-tractor for a 105 mm howitzer.
Historical: In 1939 the US Quartermaster Corps
invited a number of American truck manufacturers to
submit a bid for a 2 ½ ton 6 x 6 cargo vehicle. Of the
submissions the GMC ACKWX-353 was selected for production
and during 1940 2.466 trucks were made. The ACKWX-353
evolved from the commercial ACX-353 truck, with military
requirements like brush-guards and towing eyes added.
In February 1941, supplies of the Timken Wisconsin
split-type rear axles was supplemented by the stronger
GMC banjo-type axles, which meant re-designing most of
the rear drive-line. Trucks continued to be produced with
both types of rear axles throughout the rest of the
production period, in more-or-less equal quantities.
The vacuum-boosted brakes were replaced by the Bendix
"Hydro Vac" in early 1942. In May same year the
electrical system was upgraded from 25-amp positive
ground to 40-amp negative ground.
From April 1943 onwards all cargo trucks had an all wood
cargo body instead of the previous used steel type.
More than half a million "deuce-and-a-half"
were produced between 1941 and August 1945 by the Yellow
Truck & Coach Mfg Co. (from September 1943 General
Motors Truck & Coach Division) and the St. Louis plant of Chevrolet Division
of General Motors Corp (1942 onwards).
Majority were cargo trucks, but numerous other body-types
like compressor truck, petrol tanker and water tanker
were made. Also supplied from the factory as chassis-cab
for use by specialist body builders. They were supplied
with civilian style closed cap until August 1942 - then
with the standardised open military cab.
The CCKW-353 in the US Army was replaced by the M35
starting around 1950/51.
