Can't disconect my Quick Conect Coupler Loader 1520

[dennis103]

If your in a pinch for time, I would go get 4 new connectors and replace them all and be done. I think you will find the roller balls in the fittings are so corroded they will never work well, IF you can get them to work at all. good luck and keep us posted with what you do.

Have you tried just grasping the hose next to the elbow and GIVING IT A HARD PULL? I need to use 2 hands and try to keep the coupling straight as it comes out.
Just give it a yank, the collar stays still, the innards of the rear part slide toward you. Just give it a straight pull!!!!

I have unscreew one hose one one of them. so I was left with no presure at all and only the elbo the male and femele. They will not come out.. one things I notice is that the Collar does not spin freeley. it does spin arond the male commection but the Elbow spin at the same time as the Collar. I think it's all rusted oout in there and the coolar kinds a weleded it self with rust. I have also tryed to heat it with a heat gun witout luck. I'll coninue to add more penetrating oil.

I feel that I will have to unscrew all 4 hose and cut the fitting with a angle grainder. that way I'll be eable to acess the Male Screw. I'll un screw the male and have to buy 4 new male and femele.

This is creazy.

Anyway I have to find and alternative to plow my driveway before doing this.

It's what I think as well I'll have to replace the male and female.the bearing in there must be welded by rust. I'm still hopping to be able to disconnect them so that I could maybe only replace all 4 female. other wise I have to cut the plastic to access the Male to be able to screw them or Cut the fitting with and anglle grinder and with luck I might be able to fit a socket in to access the Male Screw.

You could also maybe use some tin snips (or really heavy scissors, or a jigsaw...?) to cut away the plastic around the fittings so you could access the male parts of the couplers..? Just thinking out loud here. Or, work again at getting those four bolts & nuts off the plastic cover so it could be removed. (Like I said, I just permanently removed mine.)

Bonne chance!

I was eable to remouved the 4 bolt that hold it. I just don't want a break the plastic. I like things when they look factory... If I can't unclip those callar. I'll call the dealer for and estimate of the part to see what is cheaper. cutting the plastic or cutting the fitting. I might have to cut the plastic eider way...

Really? Was that necessary?

Dont worry about it, I don't have to answer that i think. I don't event understand why he is saying that. His advice was to out penetrating oil witch I had done before he mention it.

I found the diagram on ACGO site but it still does not mention what kind of connector they are.

It sound if I want a remouved them i'll have to Cut part 5 and put a wrench on low 14 and 11 and I'll have to buy 4 new part 14 and part 5 but that will be my last step.

No, wait. Don't cut anything just yet. I'm trying to show video I took about noon here in a Wisconsin, showing how to disconnect the couplers.
As far as 5030, he has a LONG, LONG history of being disagreeable on this forum. Pay him no mind.

 

[lpakiz]

Grasshopper, can you ROTATE the knurled collars? If so, rotate and blow compressed air in there, to try to remove dirt, rust and junk. After the collar is rotating and clean as possible, try to rotate the elbow, to twist the two parts against each other.

No worry I will not cut them yet. If I cut them i'll make sure I buy the new parts before. It's winter here and I need something to plow. My polaris atv does not start and it's what I normaly use to plow. I have to fix this first. Got my self a new starter it's my weekend plan.. the dam things let me down in the midel of nowhere with track on it. I got lucky I was eable to get to it with a truck and tow it back home.

yesterday I unscrew one of the hydrolic line. I was left with the Elbow,Coupler femele and male. I was eable to rotate the Elbow,and femele Coupler. I have tap,pry put oil and evrything I could think of. Then I try with somone else To grip on the Elbow and and collar to try to have only the collar rotate... No luck... the collar is sease...

 

[lpakiz]

Yeah, if the collar must be slided back to unhook, you need to get that collar loose first.
But with my style of couplers, that collar never moves. ALL the other stuff on either side of the collar shifts, but the collar is securely fastened to the bracket. It cannot move or turn.
I sent you a private message,requesting your email address so I can send you video of how mine unhook.

 

[kwbretired]

Are these couplers designed to pull apart if hose catches on something? On my couplers l have to push in then jerk outwards to disconnect.

 

[irvingj]

Ipakiz, thanks for clueing me in. I wasn't aware; this forum generally does a great job at keeping things civil. (I see his post has been deleted, glad to see that.)

grasshopper, one thing you need to keep in mind: on my 2310, and I suspect a number of other M-F tractors, Massey-Ferguson very often makes things --wires, cables, hydraulic lines, etc.-- just as short as they can while still being able to do the job. If you cut off your couplers, your hose may well end up 1-2" too short to work with a new coupler fitting, making it necessary to replace the entire hose.

Some of those are long! If you end up replacing the hoses that are connected to both male and female couplers, that's a total of eight hoses, not a job I'd look forward to... though you would end up with new hoses, not necessarily a bad thing. I've had to replace three of my hoses so far -- a 2007 model purchased in 2008, now with a bit over 1000 hrs on it.

Actually the couplers may be "Safeway" brand (S40 Series) (AGCO does use them on some loaders) , so check the name & numbers on collar..... [Correction] It appears on my installation the collars on female can go either way to release the male...

Also its odd that the females are on hose and males on valve body puts a hole different slant on how to release them (per diagram in post #28).... Probably need to push down on collar and pull up on hose (elbow) at same time....

my gc2400 uses s40 series on the dl100 loader have to push coupler down then pull collar up to release but thats with collar being on the LOADER side vs tractor side.
fwiw on my setup the s40 connector makes a real easy way to drain fluid on gc series of you overfill. disconnect any one of the 4 loader fittings use the s40 on hose to bucket actuate the circuit hose connected to and bingo...excess fluid drained.
do not ask me how or why I know LOL

Just applying PPlaster or brake cleaner and not rotating the sliding collar while applying it does nothing to dislodge the crud under the sliding collar. Have exactly the same issue with one of my loaders on one of my tractors, it gets crud (dust and stuff) between the sliding collar and the body and requires a flush with PBlaster to dislodge the crud but, the collar has to be rotated while applying the solvent and mine are extremely tight to get to as in no room to work at all.

 

[lpakiz]

Does anyone know if the forum will only accept pictures and not video? I have a good video of me pulling them apart and re-hooking them several times, but alas, I'm not smart enough to get them to post here.
I click on the paper clip, go to my photo library and I can attach any of my still pics, but no videos appear in my library.
Or would it have to do with file size, rejecting anything over so many MB?

 

[lpakiz]

kwbretired,
The couplers would disconnect automatically IF the hose had a straight pull. Alas, the way we are set up with elbows, the coupling will bind up from the side torque and won't release. But yes, on a straight pull, the hose just comes out of the body with no damage.
i had a 1954 Case Model 400 tractor that was set up that way on the rear remotes. Pull type plows were set up in this area with hitches that "let go" if you hooked a stump, root or rock. Of course, you could never stop in time, so the hose got ripped off every time. Didn't make Dad very happy. But with these "new, modern" disconnects, it just unplugged the hose.
If you care to see video of me unhooking mine, PM me your email address and I'll attach that file for you..
