Major components
Sorry about that -- all the 300 series machines we had were 12V71's up front and rear. Some of the older units (333F's) started life as 12V71N's and later were "upgraded" to turbo units. The description of the gearbox/rear driveline/diff is is indeed similar to that of most scrapers as you describe though I don't recall the number of gears in the unit (insert 10 year memory fade). I was always under the impression this was an in-house WABCO design as well as their touted "traction sensing" differential.
As we were seeking spare parts (in the later years) some of the smaller components were available direct from the OEM manufacturer as well as WABCO but the major components (front drop box, PTO box, rear drop, F&R diff, planetaries) were only available through donor machines or a machine shop we had building new gear sets. We never found an original manufacturer of Eaton, Rockwell or other brand that was a compatible replacement.

mmourer ,
V12 direct coupled to 5965 allision with a 3 gear dropbox ?? back to diff via a short tailshaft , diff being a ( eaton 500 ) ???
did all models have the same power unit or where they the V8`s with smaller g/box`s and diffs ??
