Apologies if this duplicates any previous post, I've looked and couldn't find anything. I'm still a novice when it comes to repairing these old crawlers.

Started doing a bit of work to my someday project, twenty two. Had been parked for a while, not certain for how long, engine starts and runs reasonably well but has issues in the drivetrain. When I first started it wouldn't turn right at all. I followed the operators manual on washing out the steering clutches, in case they'd stuck with years old oil & grease etc. and this seemed to help the situation, regaining steering. However, when I put a load behind the tractor I lost the right steering again. What's worse is that when I pull back on the right steering lever the tractor stops entirely, even without a load.Any ideas why the tractor stops when operating the right steering lever? I've attached photo of tractor and the steering clutch adjustments, if it's anything like D2 looks like they still have some life, could this be overcome by adjustments?

Neighbor had a Cat 22 break one of the drive shafts. I don't remember just where in the drive train, but acted as you describe. He was always very careful, very worried about service and all. He was driving across country moving a one way disc. So it was not being used hard.
But on a bigger Cat that was new to me, tilling a crescent moon shaped field. So using the clutch a lot for the gradual, but continues turn the springs finally gave up . They did not press the clutch plate hard enough to drive if the other side was disengaged.

So until it is taken apart no way to really know what you have.

Looking at the photo of the steering clutch adjustment bolts, it looks like bolts need to be backed off some. It’s interesting that the bolts look like they have never been adjusted.  Make sure there is "free play" between the tip of the two bolts and the throw out arms. Just like a car clutch. Once you know the clutches have full spring pressure on them, you can pull back on the steering levers and feel the amount of pull it takes to move the levers back. When you are pulling back on a steering lever, you are feeling the amount of pressure that the springs are putting on the clutches. A light pull means thin worn clutches with expanded springs. Bill
