Pressure in FEL lines when re-hooking loader

[mark2610d]

Sometimes (but not every time) I go to re-install my 724 loader back up I find that I have excess pressure in the loader lines to the point they will not connect without breaking the lines and bleeding off some pressure. Anyone else have this problem?

What causes this? Is there something that I need to do to keep this from happening when un-hooking the loader? All help appreciated.

I did have this problem. two things basically causes this. 1. not bleeding off before disconnecting 2. changes in temps.

solve first problem when you turn off the tractor, move fel stick in all positions. up/down, left/right. Luckily on my BX I can go in circles a couple times and it does the job.

the second problem is basically when you leave the FEL in the sun, pressure goes up in the hoses. the asnwer is obvious here - put it in shade or wait till the temps go down like hook up first thing in morning.

One other thing is to make sure of is before you unhook the hoses, make sure the bottom of you bucket is flat on the ground. If it is not, then the weight of the loader will be on the cylinders and put pressure on the couplers. Before I started doing this, at times the pressure would be so great I would have to take a punch and a hammer to the coupler to release the pressure.

Had this problem with my BX2660 and it gave me fits. Finally loosened one of the hoses to relieve pressure.

I believe everyone has covered the causes and solutions from having experienced the same as you describe. I'm sure you are aware, but someone has to be the "safety police", take every precaution when releasing pressure from the lines /couplers. That oil will penetrate your skin faster than you can say ouch. We don't want to hear of any mishaps.

Take care,

I often have this problem with the loader on my JD 3520 due to the weight of components on the cylinders. Can't put the bucket flat on the ground or the quick-attach won't come off. Pressing the male couplers briefly against a metal surface will bleed them enough to solve the problem.

The permanent solution is to get an extra pair of connectors and loosely plug the pipe thread end so dust entry is prevented, but there is a slight leak. Put the extra connectors on the hoses promptly when you take the loader off. This will automatically bleed off excess pressure from thermal expansion as it happens.

Great idea Curly Dave!
Then I'll just let them drip into a coffee can or something.

Thanks,
Jake

That's the way I've had to do it. Works great.

This sounds so easy and simple....not. I tryed it and could never get it to release the pressure. A metal surface would be specifically what? How do you get that metal surface to press in the ball to release pressure? I'm sure I could whack it with a punch if I had enough hands. Guess these methods of pressing with a metal surface can't cause damage? I like the extra connector idea but I'm not 100% sure I'm understanding it. Send pictures! Also if I can't get original connector to attach to relieve pressure, how am I going to get the extra one to do it?
