Backhoe Unable to reattach backhoe

[bruschi54]

Hi,

I am hoping someone can help me. I have a MF 2410TLB with about 15 hours on it. This morning I took the backhoe off for the first time. This afternoon I cannot re-attach the backhoe. I cannot get the hydraulic hoses to connect! It seems that the "nipple" on the backhoe end of the hoses is too stiff to allow the connection. Does this make sense? I did leave pressure on the bucket and both stabilizers down....can there be too much pressure in the hose? It's also warmed up about 30 degrees F since I detached the hoe.

Has anyone else had this problem? Is there anything I can do?

Thanks!

Not sure if this will work for you but I always rest my backhoe on cinder blocks, that way I can take the pressure off of the system.

Yes. Always sit them on something and relive the pressure. Also be sure the tractor is off and pressure was relived from the tractor by moving 3point hitch controll up and down and moving rear remote controlls up and down. On new hydraulic fittings it takes a bit of stregnth to connect them. Did you check the manual for instructions on how to hook up hydraulics.

Thanks for the replies! Unfortunately, it's too late for me to rest it on something (it's already off). And I am certain that I am attempting to connect the hoses properly (was able to attach and use 3 pt attachment this morning).

Does my original assumption make sense? I can't connect the hoses because there's too much pressure in the lines (due to temp rising). If so, do any Massey owners know of a way for mw to release some of the pressure? Has anyone else experienced this?

This might go without saying, but include resting the back of the backhoe on blocks, not just the front. This is a little tricky to keep the balance. That way you can relieve the pressure in the cylinders AND make it a little more safe if the kids climb on it and start pulling levers. I lock the boom, pull the dipper in and uncurl the bucket to where it also rests on the ground as well. Disconnect on concrete if possible. Mine also has a pressure relief that relives the hydraulic fluid to the ground if need be.

Two suggestions...

operate the BH control valve levers a couple times in both directions

crack the QD fittings on the BH hoses to relieve the pressure....

OK, I'm a little surprised nobody's had this issue before, but it's easy to fix. Take a rag and cover the male quick connect. Double or triple it up, for safety and so you don't damage it. Take a hammer and give it a few quick hits. You'll have to hit it pretty hard and oil may still fly right through the rag, so don't look at it. After a few hits, try again, if it still doesn't work, hit it some more. This happens ALL the time when you remove a bh and don't support it.

This happens to me also I just tap the male end on the mounting bracket to release pressure if I can not push the connectors together. Also you do know you do not have to pull back on the collar on the female quick connect? The collar can be pushed toward the connection instead of pulling making it easier to connect.

Thanks for the suggestions and information everyone! I am happy to report that I tried again a few minutes ago and was able to reconnect it now that it has cooled off a bit and the hoe is in the shade.

Thanks again!

Common problem - hydraulics heat up. If you don't want to wack off your hose try cooling it. I've done it two ways - hosing the hoses down with cool water and waiting until morning. Wacking the hose end does work but you stand a small chance of damaging the fitting.

Yup. I had this same problem re attaching the FEL. Got tired of messing with it and when the sun went down hooked it right up. I'll leave mine in the garage next time. ;-)

Look for a pressure relieve vent, mine has a little petcock valve.

Its really not a big deal to push the male quick disconnect's ball bearing against a flat surface to make it bleed. You don't even need a rag though I recommend one. Close your eyes!

You are right. All of my male quick disconnects are tractor mounted. My problem was from the female ends on the FEL. I had left it in the sun on a very hot day. I usually take it off in the garage. It made it very difficult to put back on until I went out after sundown.

Mine is the original 2 hose system. I can unscrew the end of one hose, and bleed off the pressure.

I probably would make a hose to connect between them to act as an expansion tank, if I took the hoe off more often.

There are also connect under pressure quick connects available.

"Also you do know you do not have to pull back on the collar on the female quick connect? The collar can be pushed toward the connection instead of pulling making it easier to connect."

Wow. So simple. Learn somethin' new every day! Yes, I knew that the collar could move both ways, but it never occurred to me that you could actually connect them like that! Always have to fight with the BH hoses, which are not "anchored" to anything, while wishing I had a third hand!!

Thanks, Doug, I'll try that real soon!

Still remember the 1st time the BH on the New Holland refused to mate. I messed with the connectors until I was blue in the face, then called the dealer. He came right out and showed me how to tap the connectors with a hammer to relieve the pressure.

After that incident I took a copper cap and short piece of copper and soldered them together. Now I just slide the simple gadget over the end of the hydraulic connector before rapping it with a hammer. The soft copper protects the coupling face and the hydraulic oil is directed away from your face.

That is a great idea! :thumbsup:

Thanks! I believe a lot of good ideas seem to be the simplest ones.
