Tracks on CCKW

[Lang]

In my scrounging expeditions to old dumps in New Guinea I found many sets of double axle chains. These were not flat plates as in the above film clip but just looked like ordinary wheel chains but went right around all 4 tyres on the rear bogies.

There were so many of them I am inclined to think they may have been part of the standard equipment for GMC's in SWP area.

In 1965 at Monegeeta Army Proving Ground, we tried out the full track system on a US6 Studebaker. Great fun. Would go just about anywhere. The steering wasn't that heavy. I thought it would have been, but was pleasently surprised. The outer front wheels were fitted with a smaller size tyre. This was to aid steering on hard ground, as without the tracks, only the origional tyres on the front were making contact with the ground. Before fitting the tracks, we let the tyre pressures right down and after the tracks were fitted, the tyres were pumped up to tighten the tracks. This was not an official trial, just a "let's see what it's like" effort,one Saturday afternoon. Unfortunately we took no photos.

Two truck generations later, this is what a Jimmy could do:

Thanks for that link, Hanno. Those tracks in the photo are usually used on the front wheels, the rear was set up as a full track over both wheels. At Monegeeta, any and all combinations were tried with varying success. We spent many hours trying to break the prototype International Mk.5, 6 x 6's, once again with varying success.
