Caterpillar D3b Proto-typ

Hi Team,
from my dealings with Antarctic Traverse Machines it looks like a 3208 powered modified D3B for just such use.
At The Dealer here in Australia we used to modify machines for The ANARE (Australian National Antarctic Research Expeditions).
Back in Operation Deep Freeze the USA had D2's with D4 Engines and other weird set ups.
Of note is the swinging powered draw bar on this unit, one of the Deep Freeze D8's had such a thing. This enables the load pull center to be shifted which has the effect of steering the machine in a large radius without having to use the steering clutches and brakes. This is very usefull to make slight direction changes when traversing over long distances.
An article I have in an old Dealer Magazine tells of the "tail steering the dog" When I have time I will try and find it.
Hope this helps.
Cheers,
Eddie B.

Wouldn't something like that that was going to get used in subzero conditions have a little better cab?

I would think it would be more for muckland farming, it also has self cleaning shoes.

The D3s are made in Japan so I,d be afraid to operate it for fear the throttle would stick wide open and you couldn,t shut it down and you,d run over somebody or something. Be careful if you do operate one, HA HA.I don,t think you have to worry about a D3 but boy this car problem has really turned into a mess hasn,t it.
