I finally got this machine out of the corner to further investigate. After setting it on stands, I was able to get the wheels to turn. I found there was something loose and rolling around in the axle housing. It would jam the carrier housing locking up the rearend. I've been busy working on it and pics will follow soon. Some upgrades are in order.

It going to seem like I'm going fast with these build posts. That's only because I'm farther into this than what I'm posting. So here goes......

After jacking the 140 up and finding a busted diff, I was thinking of what to do. Some time back, I had gotten a collection of parts that came from a Duetz 1920 ultima. Pretty large machine. 400 series big. Anyways, with this package i got a good Peerless 2600-001. That's the same rear in the 420, 2 range and locking diff. I think you know what happens from here....

This was the initial tear down and mock up. As you can see, it longer and taller. Everything else though, seems to look good. To be continued......

If you weren't so far away, I have a 140 rear end! Don't have enough parts to build the tractor.

I've had access to a couple of them. I've been waiting for an excuse to use this rearend for a while. Appreciate it though!!

Once I mocked things up and realized this is more than doable, it was time to tackle this nastiness. The Sunstrand 15U has a splined input shaft unlike the roll pins style on the original. Clearly the driveshaft and clutch have to come out. I unbolted the driveshaft from the disc and proceeded to remove the engine and all. After wrestling with the clutch it was finally removed.
20170310_220708.jpg
I have 2 driveshafts to choose from. One from the 1920 Ultima and one from a Deutz 1916. After some measuring, k went with the 1920. It was without the cooling fan and shorter. There's no room for a shaft mounted fan and the 1916 shaft was too long.
20170130_211104.jpg
I also had to swap the flywheel on the engine. The Deere bolt hole spread was too small. Luckily I had one on the shelf. After all that, I ended up with this.

And this
20170312_183241.jpg
Much better.
20170313_225759.jpg
And another mock up. It's looking much better.
Enough typing for tonight. Continued tomorrow....

Interesting shaft swap.  I have a 312 that I am working on and the driveshafts are problematic.  The universal joint has potential to solve problems but the space in the closed frame 300 tractors is limited.  Thanks for the inspiration to rethink my project.

Well...since the driveshaft is in its position. It's time to move on to mounting the rear axle. After some measurements, I cut and drilled some angle iron.20170325_162226.jpg
That makes my axle mount. I also have something planned for the extra out back.
20170326_215355.jpg
And the axle bolts in. Fits pretty nice. I ended up adding another 1/4" plate to raise the frame up a little bit. The drive shaft clears but was a little too close. Looks good now.
20170326_215409.jpg
Swapped the fittings from the old pump onto the replacement. Now I have hydraulics. Pretty nice for if you ask me. So, my ride height is pretty close to stock. It did extend the wheel base from 46" to 48".

Plenty of room for the linkage to take advantage of the 2 speed and locking diff. Right now my plan is to install the diff like the 420. I haven't sorted out how I'm going to add the range selector. Thought about a lever in the wheel well kinda hidden. That depends on how the 26 12 tires on waiting to add fit in there. At this point, I'm going to have to remove around an inch or so from the hydro linkage. I swapped the original pivots and adjuster from the original 140 pump. Having a real neutral is pretty nice too!

Also on the agenda is a 3 point. We all know the closed frame 3 points are pricey and tough to find. Well, now my 140 is an open frame tractor. Kinda changes the game a bit. I haven't gotten that far yet but will be soon. Plus, this machine will now accept the 2000 rpm rear pto. It would be a bolt in upgrade.

This is the actual point I'm at now. Everything from here on out is "real time". I still need to source a set of 12x10.5 wheels for the rear. I already have a set of tires. In order for the ground speeds to be good, I think the 26" tires will help. I'll update once I get to working on it again.

I missed the two-speed swap portion of the threat.  This is a great swap for a worker and gets around some of the challenges with closed-frame machines like my 312.  Do you have any pics of the mount plates by themselves?

There's nothing real wild. The 2 pieces of angle unpainted you see in these 2 pictures. Drilled 4 holes, 2 for axle, 2 for the frame. One thing to note here, I've kept everything bolt on. If I decided to change back to stock, I could in a few hours.
Oh and don't forget there's now differential lock with this rear end. This upgrade also enables me to still use the belly and front attachments that the 140 had. Mower decks and all. Horsepower will be it's only limitations. Which really has not been an issue. Although a 16 would complement it nicely

My kind of swap!!!!  My 120 is filled with many little improvements that are easily removed.  I think the K341 is a "must have" on your list!

This really has me rethinking my 312 project since an Onan 316 showed up cheap locally...

Well here goes the first start..
https://youtu.be/dL5dYQ2_Mmc
Once it started, I was happy to see everything spinning good and not hitting. Seems a tad bit smoother in the driveline department.
Notes as follow
1. Operates backwards. Push lever forward it goes reverse with speed and power. Pull lever backwards, it goes forwards with reverse speed and power.
2. No lift. I think the backwards has a lot to do with it.
IIRC, I can flip the charge pump on the front and solve both these issues. I hope at least. I think the Sunstrands have this capability, go from CCW to CW and vice versa. Anyone's input is appreciated.

So I've been thinking......
Really just wrapping my brain around why I ended up backwards considering both the 140 and donor tractors are Kohler powered. Both of which are also driven off the flywheel. Why still are things backwards? A light just came on!! It's in the rear axle. The main driven gear in the rear is being driven from opposite sides. Which in turn means, the factory 140 output must spin one direction. Where, the donor (duetz 1920) must spin the opposite. That explains the differences in the 2 different charge pump orientations. There's only so many variations in these pumps. Realizing how many manufacturers used similar parts in their engines and drives systems really lays things out to understand. At least to me. That's what ventured to me in this project in realizing what parts will better match this setup. Hence, sourcing from a Kohler powered Duetz (Simplicity) They're closer cousins to the Deere 300/400 series than most people think. Sorry, thinking out loud and this is good info if someone was to search this subject.

The lowly tear streaming down my cheek isn't about the stupid deere, it's over the Ultima!
