Cleaning the a/c core on my skid steer I must have tweaked this fitting on the heater core a little too much. Anyone have any idea on how to fix something like this, preferably without removing it... Talk about a major PITA to clean, the a/c core was completely plugged with mud so I was getting virtually zero flow.

??manually recrimp the hold down teeth thingmajigs??
Looks like a special tool compresses the four teeth to push against a oring type suface.

Very precise persuasion to the coupling might work.
What have you got to lose?
Maybe a special tool gets this done, how is that serviceable??

My guess is that it's not really fixable without removing....but maybe hit the crimped areas with a punch/hammer?
 
A new heater core is over $500, yea Kubota is smoking crack... I thought about trying to recrimp it and might still try, but I think I might would do more harm that good.

Kind of wondering if cleaning it really well, then adding a metric ton of epoxy on it might do the trick? Maybe put a hose clamp around the pipe to give something more for the epoxy to grab on to as well?

My guess is the tweaking pinched the O ring and it’s toast. Nothing to do with that but replace the O ring. :(

Yea that's what I figured, but are the o-rings replaceable? I've never had to crimp one of these, not sure if they can be uncrimped/recrimped?

O rings are pretty much self sealing as long as there is some pressure on it and the joint is somewhat tight. Not sure what crimp tool would work but I’d be willing to bet there are some easy ways to crimp it with some random tool you already have laying around.
 
Yea it turned out to be easy. I took it apart to replace the o-ring in case it was damaged when i twisted it, but the o-ring was fine. Put it back together and crimped it with a screwdriver, so far so good, not pretty but it worked. Crisis averted.
