Seems like the 7060 carried on the # between the maroon/black belly, were there other models that did? What made ALLIS dump the 7050/7030 for the 7045 ? Thanks

The 7030/7050 were the first of the new generation 7000 series in Jan 1973. In the Fall of 1974 the 7040 replaced the 7030. The 7060 replaced the 7050. Each new tractor had 5 more HP and would eventually have the Power Shift transmission. At the same time the 40/60 were released, the 7080 was also introduced, as the largest 2WD tractor built at the time. The 7045 didn't come along until the Fall of 1977.

I believe the 7000 was both maroon and black belly, depending on the year.

Heres a link to this topic being discussed in March of 2020. Don’t forget about the 7580 & 8550 4wd models.

No, there was a black chassis 7000 for a little over a year, then the 7010 replaced it. Early 7580 were maroon, later were black, and all production 8550 were black.

Quick run down, all 7030, 7040 & 7050 were maroon chassis only.

All 7010, 7020, 7045, & 8550 were black chassis only.

7000, 7060, 7080, 7580 could be either.

Any idea of what JD 2WD of the 7080 era came close ??

Thanks for the info !!

Allis-Chalmers "improved/refined" the initial 1973 7030/7050 models and the 7000 series line continued growth. PRIOR TO 1973, AC invested in a NEW "high quality/cost-cutting efficiency computer controlled flexible machining center" mostly quoted from Norm's 1914-1985 Allis-Chalmers book. I think these machining centers basically allowed better consistency of tooling(milling/thread cutting/etc)of the rear drivetrain components (clutch/trans housings, rear-end housings, & rear axle housings)of the 7000 series tractors. These trans/rear-end/axle housings consist of a large cast-iron components which could be fixed into a movable jig cart that allowed them to become aligned/stationary once inside the machining center, yet movable on their cart's caster wheels. That was a big leap. And to add to that, some of the other NEW features for the 7000 series were their 20 speed PD transmission, torque limiter, variable hydraulic system, 426 piston oil cooling, Acousta Cab, removeable hood side panels, etc.. And then in 1974, the 12 speed power shift transmission after the initially planned Allison Automatic Transmission realized to be infeasible.

Here's some older AC forum posts inwhich Tbran discusses in length about some it.

There is a post in the classifieds for a 7060, this machine has "spin-out-power-adjust" wheels Confused

. Why did ALLIS drop them after the XT era and then bring them back? Or did this machine in the add have some type of aftermarket rim/wheel set-up ?

You are a little confused. The power shift rear wheel was introduced in 1948 on the WD tractor. It continued thru the 175/185 tractors until 1981, nearly 33 years as standard equipment. The 6060-70-80 tractors also still had them. Why is that ?? Because there was no other way to adjust the rear wheel tread !! None of those tractors had a "bar type" rear axle. The D-19 and D-21 had bar axles and the power shift wheel then became an OPTION as it was more expensive than the two position rear wheel clamping method. The feature was never dropped. It became an option. Also, since the maybe early 70's farmers didn't need to change rear wheel settings like they used to, so why even have the power shift wheel on larger models ?? EDIT: All 4-pinion 7000/8000 series had to have power shift wheels to achieve 60-63 inch rear wheel tread. This was because engineers had moved the outer axle bearing farther out for strength/reliability. 7045's and up. 8050's and up.

Not confused, just didn't realize it was still an "option" on the larger units .I saw the pic on the classified section and was surprised to see that set-up AND the axle hub assembly tread adjustment. Thanks for the clarification .
