Hi Geoff, the 1410,12 has the same box as a 1394/1494 but the diff and rear axle housings and reductions are 15/16 size. 7/43 diff ratios are in the 1494 and down and the 8/41 are for 1410 up.

1294 4wd

Changing the 1594 6-cylinder engine to a 1494 4-cylindrer engine will completely destroy the usability and value of the tractor.

Who said anything about changing the 6 cylinder to a 4? Not me ! I loves my 6 cylinder!
I will find a 4wd 1594 and just make a swap of the cab and other necessary bits to make mine fwd. And keep the other as an open station rig.
If I were desperate I might consider shoe horning in the 6 cylinder into the 1494 running gear but I am not, so the hunt is on for a 1594 fwd or a 51/5230 or 40 . These were also awesome tractors and had a real nice 6 cylinder Cummins diesel.

Well, who wrote this then: "Will, say a 1494 nose and axle fit the 1594 frame/ engine housing"? And one more thing, the engine in a Maxxum (51-series tractor) is not really a Cummins, but a engine based on the Cummins engine and called CDC (Consolidated Diesel Company).

Keep in mind a 1690, 1694 or 1690t are similar to the 1594, with the 1690t and 1694 turbo, the only differences between 1594 and 1694 is turbo and or manual or power shift trans.

People in US are calling the transmission power shift but the correct name for this transmission is hydrashift. Four gears without the use of the clutch in 3 forward and 1 reverse range. The 1964 was only available with hydrashift transmission.

Hi ollek you are correct hydrashift is the correct term, you most likely know more about the 1410 connection to the 1690 as i understand it the 6 cylinder motor was bolted up to 1410 back half with the spacers between motor and gearbox frame castings, it appears parts like the gearbox layshaft ect are the same by part numbers,so the whole gearbox diff unit should interchange between tractors it appears the diff crown wheel could be different ratios. Also one ratio of the final drive gears are the same although the housings have different numbers as the 1690 progressed for cab mounts ect including different gearbox cover castings.

I was wondering if just the casting that held the axle was the same as the 1594 casting but it is not obviously ,now that I was able to look at them side by each the 1494 is a much lighter built unit.
And yes the Case 51/52 series was a CDC made engine, but it shares more parts with the 5.9 Cummins that I care to mention.
Anyways.... I found a 1594 for parts so I just need to get after it .
I need to find a good manual on the hydrashift so I can rebuild/modify the one in the donor machine. I need to know what the max pressure's are in the hydrashift unit so I can be sure I have that upon rebuild.
