AC Running Gear

Does any one here know why the AC 7 ton running gear has 2 different models? Model 700 and a Model 701. I would assume they were both made by Electric Wheel Co. Different style boxes used on either or hoist/ no hoist?

Does anyone know where to find tie rods for an AC running gear?

The 4xx/5xx/600/700/1000 are of the same concept...The 3xx is of a different design.  I am quite sure that the early 700 is different than the later 701 because you should find that the 701 was sorta beefed up for the chopper boxes.  Thus having a 72 inch wheel tread...I believe that the gear ranges were from 66 inches to 72...I think that is how I remember it....HTH...Dale

Original AC dealership sales literature offers good insights to AC wagon running gears. One insight & subject in question, “which years were specific models produced?” can be answered using this literature. Usually most AC sales brochures have a date on their back cover near the bottom. For instance, the AC sales brochure for the 300, 405, 500, 505, 701, & 1000 is labeled FE-379/668, on it's back cover page. I assume FE-379/668 to mean Field Equipment 379, printed 1966, August. This makes sense, since these running gears all contain the newer 1965 triangle AC logo decal & a white background ALLIS-CHALMERS rear frame decal.

I don’t have any of the older(pre-1966) AC running gear brochures, but have seen page copies on this forum that other forum members have shared. But a back cover page (the dated page) is not shared because the item of interest is usually on the inside pages. Anyone what to share photo copies of their older running gear brochure’s back covers??

I do own each of the models 605, 700, & 701 though. So I’ll share what I know from my  studying them.
The 605 & 700 models both have the older WD45 styled, ALLIS-CHALMERS decal with no background - naked lettering stuck over the running gears rear frame’s orange paint. So, I’m assuming these models to have been produced prior to the 1965-1966 era??
Another specific about these 3 gears are their ID tag’s information as follows:
The 605’s ID cat.no. is 2013776 & serial no. 6 2281.
The 700’s ID cat.no. Is 2013847 & serial no. 7 6443.
The 701’s ID cat.no. Is 2013920 & serial no. 7 14402.

The AC running gear’s ID cat.no. NEVER CHANGES per MODEL. So if your running gear is missing a stenciled “700” marking on it’s side frame, but it’s ID tag cat.no. is 2013847, then it is in fact a model 700... 
The serial number’s first number denotes "tonnage" which is then followed by a sequential production number. These sequential production numbers per a model or more importantly "tonnage model" (605 (6 1/2 ton) probably became the 700 (7 ton), which later became the 701(7 ton)) were just continuation numbers within a specific tonnage. So you'll probably never see a 2013847's 7 2280, because that serial number probably belongs to a 2013776's 6 2280.

If I can remember which two I was working on I will check again. I recall they were 68 inches and 72 inches.  sure it was a 700 and 701 and remember possibly that was of some significance of the 701 designation...Think it is only the axle stub that is longer and has the reinforcement cap on it...The pic is of the early gear I found....Dale
