Put together truck?

Bob · Post by **Bob** » October 5th, 2007, 5:57 pm

I have a AA truck with a cab date of 2/14/29, frame # 1C74517*, engine
#*A4067453 and a worm drive rear end with TT marked on both sides of the differential. Is this a "put together" truck? In other words are these parts and pieces of several trucks? Any help anyone has would be greatly appreciated.

The first AA worm drive rear axles have TT markings on them. I am not sure when this was changed.

A4067453 is an A engine number. So, the engine is not original. But, this is not uncommon. When an AA engine was changed, an A engine was usually used.

I don't know what "1C74517" is. For the US the frame number should be AAnnnnnnn (where n is a number). There is a star on each end. This is the original engine number.

Is there such a thing as a "cab card" like modern day trucks? Also, I have located a worm drive rear end that has a 2 gear spider rarher than 4 gear and has tapered "timkin" style axle bearings at the differential rather than ball bearings like the TT has. Is there anywhere I can read up on which trucks were made of what components or when different changes were made. I appreciate your response Neil--Thank you.

I have not heard of a "cab card" for the AA's. I have not heard of the axle which you reference. Maybe someone has some information.
