B2650HST with cab oil cooler leak.

[Goldsmith1]

I was working on our road yesterday and the oil cooler dumped pretty much all of the oil out. It seems to be leaking right where that metal V is circled in the pictures. Once again I'm messing with something I have no experience with. In the picture it appears this is where the cooler is connected into the system. Is this correct, and if so do the lines just screw together? Still trying to fix our road since Helene destroyed almost a half a mile of it. Any guidance would be greatly appreciated.

030, is that an oring that might have gone bad? Do you just pull off the flat metal v 040 to take apart?

Pull the spring clip off to separate the pipe from the cooler. O-ring is inside.

I'd spray the area down with brake cleaner and get it nice and clean and dry. Run it and see where exactly the oil is coming from- the junction or from a pinhole in the tubing.

Thank you very much! Definitely is coming from that connection but not sure if o-ring or pinhole. It's pretty much out of oil now and afraid to run. It's foaming when it comes out and none is showing on dipstick. I had it running for about 5 minutes before I knew I had a problem. Nearest dealer Is a two hour round trip. Does tractor supply have a suitable hydraulic oil could use to test? They're only an hour round trip. Then I can go to dealer for parts needed.

Do I need to remove the cooler to replace the o-ring if that is what's bad, and if so should I replace both of them?

I am also not able to find the schematic for this area of the tractor anywhere. I haven't even been able to find it in the service manual.
