Friend replaced his clutch on the 1750, while it was apart the hydra shift output shaft was bad so he exchanged it(the whole assembly) with the one from a 1950T he retired a few years ago. So now if he adjusts the free travel in the clutch pedal to where it should be, he can stop the tractor with the brakes in direct over or under. And if he takes out the free travel the tractor pulls like it should, but then can't change gears without grinding. He did get a new hub and pto shaft from A&I and assume he got the clutch from them also. The throwout bearing is the same size he says, he also had to change the throwout shaft/lever from one to the other.
