Since you are on an incline, make sure you anchor the machine to something on top of the hill, it will need to be either a big tree or something that weighs over 8000 pounds, equal to the weight of the T190, after it's been secured, de-tension the track (release the grease pressure) and jack the one side of the machine up, just enough to get the machine's weight off the track. Use brunt force to realign the track and it should pop back on.
If it were on level ground, you could use the loader and bucket to lift the machine up with a block under the rear corner, but being on a hill makes it harder.
