Dave,

I sorted out the difference for Chevs the other day, see http://www.mapleleafup.net/forums/sh...184#post202184

20 hundredweight (cwt) is one ton.
30 cwt=1.5 ton..............................

16 oz =1 pound (2.2 to the kilo)
112 pounds = 1 cwt. ( and so, 20 cwt to the ton)
1 ton= 2240 pounds.

BTW. there are 63,360 inches in a mile and 240 pennies in the other kind of pound

Need I go on................Old people know this stuff..............It clogs up their memory banks. 56 pounds in a bushell. 9 gallons of beer in a firkin.......

Alright alright!................ I know!

Thanks, I think I got it now. One more thing off the curiosity list of CMPs.

One more thing to add is that the C30 (30-cwt payload) only came in 134" wheelbase. This was later upgraded as per specs above to the C60S (60-cwt payload) with the same wheelbase.
The long 158" wheelbase only came in C60L (60-cwt payload) form.

See http://www.mapleleafup.net/vehicles/.../chevspec.html

And of course, the same applied with F30, F60S and F60L Fords too.

There is always a "but".
There were 158" trucks, Ambulance and some Canadian made Australian? contract vehicles, that had features of lighter trucks (small steering joints and 16" tires). I believe they were listed as 3 ton but a casual observer might think they were either 30 cwt or a mix of "incorrect" parts.

There were some ambulances that were 4x2 vehicles in longer wheelbases. I have a front axle ( Ford?) and it fits right into a standard CMP 13 cab chassis as it has a hollow tube with no gears and is not a drop type axle that many standard trucks of the era would use. The ends are not drive types but have kingpins, and one version (that is now found a new home) actualy had an extended kingpin with extra support underneath the axle to provide additional support. Going down the road such a vehicle would appear to be a 30 or 60cwt depending on wheel sizes used. It is an oddball!

[Keith Webb]

The Australian Ambulance was on the 134" chassis and the Ford version was listed on the data plate as F60S although it has 16" wheels and 4 7/8" steering ends (the aforementioned 'small balls').

And to further cloud the waters the gun tractors were classed as a 3-ton chassis although they were on the 101" planform. Earlier ones (until 1942) had the 'small balls' because the larger 6" steering ends were not introduced until 1944.

Correct - these were usually fitted with an Ambulance body and other "large volume & low weight" applications.

See the thread Late 1945 Ford F60L with 16" wheels.
