Can't get a hose to come off

[CATMAN]

If Wayne county hose' method, doesn't work for you, then try this IF you can get a "backup" wrench on to the o-ring fitting's hex. Put on both open-end wrenches onto their fitting's and put both wrenches straight up(or parallel) to each other. Now, get a prybar or piece of flat steel(lever) and wedge inbetween the two wrenches at a 90 degree angle and with some prying motion and pushing downward of the prybar one can sometimes get the fittings to break loose.

I know it seems like you need three hands to do this procedure, but I have used this method many times on fittings that were in bad locations and I was working at arms' lenght where I didn't have the leverage/physical strenght to loosen fittings.​

I can only hope you understand this description, but I don't know of a better way of wording it. Basically, the prybar provides the force/mechanical leverage on the open-end wrenches, the farther you push and "walk" the prybar downward inbetween the "beams/handles" of the open-end wrenches then the fittings should be loosening up.

I cannot tell how much room you have under the block to work around from the picture. I would use a 3/8 drive extension with a flare nut crows foot and possibly a swivel or universal.

My fear is breaking this. I allready snapped a wrench ( a cheap Chinese one) but it blows me away that these guys can reaf these things together so darn tight. I mean, why in the heck did they tighten these things so darn much. No reason for it I can think of.

I am taking everyones advice, first by getting a cheater bar and then by removing some of the addtiional filters out of the way.

I guess I will just crank on the bad boy until it comes apart or I break something of more value.

I will also try the wack it with a hammer trick, providing I can get some sort of block underneath it.

Try a line wrench, or take a regular 6 point closed end wrench, and take a chop saw or grinder, and cut it open, just wide enough to get the wrench over the narrowest part of the hose or fitting, then slide it along the hose, to the wrench flats, then hit it with a hammer. Aluminum tends to work harden, with the operation of the hose in question, also the rubber and the braid in the hose gets a "set" in it which makes the first turn the hardest. You may also want to try to tighten the hose before you attempt loosening it, sounds stupid, but it counter-acts the "set", sometimes!

I didn't know that you have already broken a wrench trying to loosen it. There is another option that maybe possible, but messy; you remove the opposite end of that hose, then loosen that o-ring fitting(with the stuck JIC fitting) and then you rotate out the entire hose/JIC fitting/o-ring fitting out as an assembly. Once the assembly is out of the machine, you tighten the o-ring fitting into a shop vise and work on the JIC fitting/hose end out in the wide open. I have had old JIC swivel fittings seize onto their male fittings and when I did get them to rotate it tore up and stripped the threads anyway. This requires new parts when that occurs and the parts would have had to be removed anyway.

diyDave is correct in tightening the fitting then loosening in order to break the fitting loose. Just tighten it until you feel it give the slightest then it can be loosened. Done this many times on rusted brake line fittings.

Holy smokes! Now why didn't I think of that.

I agree with Wayne.. remove the orb type fitting from the aluminum block.. then worry about seperating the hose from the fitting. I have a strange komatsu/kobelco hyd cyl on an old fel... the ports in the cyl use and oring fitting.. that necks down and converts to female 3/8 pipe... it's a weird one to mess with..

Hey now.. just because you thought that gem up back on page 1, post # 6.. doesn't mean it's not a new idea now that some one else has said it!

Don't feel bad... I get that all the time...
