190XT

Would the input shaft be an issue then?

A 190 XT prior to s/n 9001 was a unit that should have received the complete driveline update about 45 plus years ago. Everything inside should be the same as any other 190 XT, or 180-185. One part that could be different would be low gear on a late 180-185. They could be a different ratio. Most everything else should interchange. Some of the 200 parts would fit, but not all.

It shouldn't be. The best way for me to describe the updated transmission parts is this.....the splined main shaft (pinion shaft) is one diameter all the way from back to front (with exception of the nose). The old parts (which are NOT available any more) the main shaft was two diameters.....smaller where 3rd gear is.....larger at the rear.

Got it, and crap....mine has never been updated then. That's why I couldn't find the parts then I guess. Any Ideas??

NONE of those parts are available. Find a different rear end or junk the tractor.

So if they could be updated back then, why can't they be updated now? Is it because the parts to update are no longer available?

Seems like a good thing to keep in mind if I ever buy a 190XT

Is this a gas XT ?? I can't believe a fire-breathing XT diesel would have gone this long without ripping teeth off of second gear while plowing. This scenario only affects XT's built prior to s/n 9001. It's easy to tell by driving the tractor. If low 3rd is slower than high second.....it's never been updated. Don't go by the shift decal because some of those didn't get swapped. The proof is in the driving.

Thanks for the info Mack and Doc. Good info to keep in your back pocket

Just a question was the early 190 the same as a D19 or are they different?

D-19 and D-17 (series 3 and 4) were pretty much the same. The early mighty One-Ninety's were different than a D-19 regardless of what some say. On the exterior they look like a D-19 rear end, but they are different inside, especially the transmission.
