    Posted: 21 Nov 2023 at 6:16am
This is the 8010 I've posted about in the past. It was sold here new, ultimately traded back in for another new tractor, resold again eventually being repowered with the Cummins engine. It was then brought in for some type of hydraulic problem that was impact related with a tree stump IIRC. A lot of money was expended repairing this damage including a new main pump and used set of hardlines/pipes which were bent up and unable to seal. The owner a couple of years later traded it back in for a new Massey-Ferguson tractor, and this one set to an implement dealer 175 miles or so distant on a dealer trade.

I was surprised the tractor is back. Nothing wrong with it; just in for routine service and it runs very well. Turns out the owner's neighbor wanted to purchase the tractor but didn't decide quick enough he wanted it. The current owner purchased it and traded in an older Ford tractor at this distant implement dealer so it is back in this area.

Thanks for sharing it's storyline. It is still looking good & earning its keep. When you say cummins, I'm guessing a 5.9 12v rotory or P-pump? If so, whats it's hp setting? Did you do the cummins repower?

The Cummins 5.9/12Valve that we put in my brothers 7020 had the "VE" pump on it. With the high idle at 2500 RPM, pulled down to 2300 rated speed for the 7020 chassis, we had 135 HP. Perfect. When I pulled it on down to 2000 RPM, I got 180 HP  !!!  Tremendous torque build up  !! A really nice 450 bushel corn hauler in 6th gear PST any hill we have and no need to ever downshift.

I did nothing to or with the tractor at all. I think one of the prior owner's did the repower but I will attempt to find out it's current settings as know the original owner's and second owner's families well.

Thanks DrAllis for sharing about your brother's 7020 recent 5.9 upgrade features/figures. Also enjoyed watching your progress thru it's engine swap. Yes, the 5.9 cummins is a remarkable workhorse. Not to bash the AC 301 or 426, but IMO the 5.9 cummins in the AC 7010-8070 units should have comparable torque at improved fuel efficency.  I realize the AC 4.9 301 is not an exact comparison to the 5.9 cummins. And the AC engines are 28-40 years older.  You mention your brothers 5.9 7020" improved torque, but what have you noticed of it's fuel economy versus the AC 4.9 301?

Brother is very happy with everything about the Cummins 5.9 engine performance. Starting in cold temps is the first thing one notices....it just starts as soon as you hit the push button. Power and torque are in the 426 performance area. Fuel economy he doesn't really keep track of, but I'm going to say pulling his 12-row White planter, it uses no more fuel than the 7020/301-TI did because it probably doesn't hardly use 100 HP even on our worst hills and the more modern engine is more fuel efficient to begin with. No regrets.

This tractor is back in with a destroyed transmission. Several gears are missing teeth as a bearing came apart and apparently rode around for a spell. Tractor is split and mechanics are tearing into it now but it's pretty much carnage in places, and untouched in others. Front driving gear and it's corresponding countershaft gear each have teeth knocked out so must have been violent. 

Really don't know much more than that but going to tear it apart fully, price parts and labor, then compare to used replacement, or reman exchange.

The 8010 Power Shift tranny has one planetary that was cheapened up compared to the 8030 and up models. They felt it was more than adequate for 110 HP . The Cummins has probably overpowered that area and she ate her pigs !!

Hope to know more in the upcoming week. So far, it looks bad however. Never been into a tractor transmission myself but have rebuilt several light and heavy duty manuals over the years. They have the books and were ascertaining how it comes apart when I left. 

One of the guys bumped a set of snap ring pliers setting on the case and they disappeared between the countershaft and gear case. My arms are small enough to get inside there and man is there a lot metal pieces where they shouldn't be..... 

That Cummins engine was originally a low power variant from an FL-60 Freightliner truck. The tag has 152hp stamped into it, but it's been "turned up" in power I'm told. I still see the original owner every now and then and will ask where it's calibrated at now.

The correct service manual and the special power shift tools will make the job easier. There should be a decent supply of used parts available, and the heavier pieces should work.
