I've had my TC40D for about 2 months, 60hrs. I have had my second oil cooler crack. Anybody else with this problem. What is the fix?

Very good question but I don't know enough about the tractor to comment. There have been a number of common problems identified here on the board and maybe the discussions have even gotten manufacturer attention.
Two things come to mind but both are stretches. I don't know if the oil cooler is part of the rad assembly. If so, there have been discussions here about excessive flex of rad assemblies on some NH models--especially when loader equipped. I also don't know if the cooler uses flex hose. If it does wrong routing of the lines is a possibility. Some hydraulic lines require very specific routing.
I'm guessing the repair is being done under warranty and is more of a pain than a cost. You have to assume that the dealer techs are doing the work properly but maybe it's time for the dealer to check with the regional rep. It could be a manufacturing issue.

I have a TC45D with approx. 110 Hrs & now am in need of the second oil cooler. One "blew" at approx 60 Hrs. Both have failed at the top, right connection where they are "soldered" into the cooler. Will discuss with my dealer tomorrow as to options & "fix". I need something done that is dependable. I have no interest in keeping a cooler on hand. It also makes a "MESS" of the radiator. ....

The line and the cooler are vibrating differently when the unit is running. This causing the failure. Different dealers in this area are trying different things to get past the problem. Yours are no different then the rest. ....

Is the line connecting to the oil cooler metal? Maybe it could be shortened and a piece of high-temp rubber hose used to isolate the vibration between the line and cooler. And/Or maybe cooler vibration could be minimized a bit by mounting it with rubber dampers. ....
