getting stuck hydro fittings off

[copperhead1967]

I'm changing out a few fittings on my BX. One is leaking a bit and the others are to match up with a test guage for checking the hydro pressure. The dealer had no luck getting the correct fittings for the BX22 as the parts numbers had been changed to the new BX24 fittings. I went to a local hose shop and got 3 sets of fittings for about the same price as Kubota dealers one set.
I tried to change them out but I'm running into problems getting them "unstuck". Seems I can get one side off but not the other in several spots on the tractor. I tried penetrating oil. Any tricks how to get them unstuck? I was thinking on soaking them overnight in a baggie filled with penetraing oil. Don't want to put any heat to the fittings.

I ran into the same problem on my 2200. The metal tubing is much softer than the fittings and once tightened down doesn't want to come off. I ended up replacing a section of the tubing. I worked for about 15 min before giving up and taking it to the dealer. He couldn't get it off either.

Good luck.
