Thanks for all the input. I do have a come-along with me as well as a smaller
B7100 Kubota to pull the bigger one around if needed. I'll see what I can do without starting it, but I tend to agree that running it from cold, as in tomorrow morning, for minute or two probably wouldn't hurt it. It's just that it's so new, I don't want to chance anything and wanted to post here in case there's something drastically different about diesels since my experience is mostly with gas engines.
The belt is still on but did spin on the fan pulley for a few seconds before I could get it shut down. I'll definitely replace it and it sounds like I just go ahead and cut it off.
I will check out the other thread on the 3800. Can't believe there's no protection plates under there.
I don't think it ran long enough to overheat and trigger any shutdown mechanisms if there is one. I had it shut down literally 3 or 4 seconds after it happened.
I was also wondering if a radiator shop could fix it but not sure they would be able to get the right end cap with the hose fitting. Worth asking around.
Guess I get to learn about loader removal for the repair. Should be fun.
This mishap was a real let down from the high of finding a 15 hour used tractor with loader, extended warranty, 5' brushhog, fancy $1000 dual blade road grader(never used), and hay forks(never used) for 15,750! Nothing like breaking it on the first day.
