Timken diffs were manufactured by Timken Bearings.
the Australian and Canadian service bulletins do have some information on the differentials.
it is not correct that all timken diffs were open tail shafts.
the differentials from late 1930 till end of production were in fact closed.
the easiest way to tell is if it has a torque arm coming of the diff housing. the later differentials had radius rods like the car and US AA's.
there were numerous wheel from discs, wooden and dual spiders used on AAC trucks.
if you need more assistance please contact me and i will be glad to assist.
I found the timken diff set-up procedure in my old Dykes manual, also I ordered a copy of the AA truck supplement by Jim Schild and "the restorer" with the section on trucks, so I have some reading to do.
I got her all home, an inventory shows lots of the little stuff is gone or wrong (bolts, screws, some trim, pop out ect.) but I'll track down what I need.
I'll post updates on how she progresses if anyone is interested. Hope everyone has a great weekend
