8070 experimental

I bailed out the end of 1984 and understood that was stopped by Deutz before it was prototyped.

Head scratcher for sure. I have never seen an 8000 series with factory 42 inch wheels, so those cast rears may be right? The serial number and age of the tractor don't make it a late production tractor and yet it looks like it has the wide planetary gears plus the fill tube for the rear end is moved. I don't see any advantage to that? The front axle is certainly different, Hyd. cylinder with a tapered ball joint,they needed that, king pin caps, they needed that also,and even the tie rod is different,upside down. Another minor thing is that the fuel tank breather hose clamps are a worm gear design, I don't think that is correct. I will say that it does have the late Allis frame ty paint job. That was embarrassing back in the day.

Ihave a neighbor with 8070 with 42 in duals I believe are factory original.

I have a 8070 with 42" cast centers. The wide planataries would match a 1600 serial number

Aren't the wide planetaries only used on the early 8070 two wheel drives?

Yes.The FWA's used the 8050 rears and ser#2662 they went to narrow (8050) rears on 2WD 8070's. Mines 30XX 2WD with narrow finals.Norm's book says testing proved they didn't need the wide ones but maybe the truth is they used up all the leftover 7080 finals?

Putting either tranny in front of the other would have killed the 2nd tranny due to the large increase in torque being delivered.

That would depend on engineering to work out.......right?

I've posted this before, but as a reminder for what an 8095/9025 really looked like:






Those are 20.8-42 rear tires.  The test people referred to the tractor as Big Foot!!.

Isn't he dead?   If he ain't dead he certainly doesn't answer his phone or return calls.

It's something they put together. Check out machinery pete on you tune allis collection. The hire man talks about most of the pieces

The hire man talks about most of the pieces Yeah, I watched the video, and 'Ol Pete, kinda acts like a used car salesman during that specific conversation.  He keeps repeating the "experimental" when the farm manager clearly states its just a Hodge Podge of parts they had around, or bought from Allis.  Nothing truly experimental about it.  Never assembled by Allis, never tested by Allis, never known to Allis per se.  Maybe it has one of the 8095 rear ends in it, maybe it doesn't.   Heck, we have hundreds of 70xx series pieces laying around, maybe I could "Put one together" and call it an experimental also, and stir up a big internet buzz!!

The front axle and the back wheels is the experimental parts from the 8095 and maybe the rear differential but rest is pieces put together.

my post didn't come out right, I meant Joe mentioned putting a PD two speed clutch and reduction gear set as a 'splitter' input to the power shift.  Not the whole tranny.  Enough room w/o much stretch.

Everett Huntley would be the one to clear up what's what . If I remember correctly the 8095 rear end is the 8070 2wd rear end big axles coupled to the power director of one of the big 4wds ( maybe the 4w305). The frame on the 8095 is longer and there is an extra sheet metal piece in front of the cab to account for this. I'm not sure on the front axle but it sounds as if you could build the 8095 drive train from existing parts.

Sige is a very common fwd axle over the pond and no they didn't just make a axle for Allis Chalmers.. Allis bought the axles from them over seas for the 8000 series.. It is avalible for 2800 euro.. Used. My guess is they found a axle and got it to fit.. The other 8095 hunnly bros have is totally different yet then this one on the auction. I just hope some one doesn't pay big money for what in my eyes is a replica!! If they do I will have to ship over a few axles and get building.. Lol just my 2 cents

I wouldn't call it a replica either. A replica would be a totally made up machine. This does have the serial number. Not waying that makes it worth more. Watch the Machinery Pete video, the guy says it basically came in pile and they put it together with what they had. He also mentions moving the front axle ahead. People are going to pay what they want to pay. Remember that "model H" a few years ago? Case and point.
