Pressure in FEL lines when re-hooking loader

[northernjake]

John,
The way Curly Dave explains it, I think I understand. If the loader hose ends are male (I believe), get the matching female ends to snap on as soon as you remove the loader. If you lightly threaded a plug into the threaded end of the female coupler so as not to hold pressure, when the heat built up pressure in the lines, it would leak through the couplers. Or to exagerate, rather than lightly thread a plug, stuff a bit of a rag in the threaded end.
I hope I have captured Daves intent, and if so, I hope you are clearer.

I had the same problem. It is always with the middle two connectors on mine. I keep a large diameter bolt in my tool box. If the connectors do not go right on, I press it into the center pin on the female connector which is still on the loader and it releases the pressure. Obviously keeping it away from my face. Since I learned to do this, I have never had a problem getting it back on, but even with a lot of wiggling of the control after shutting off the engine and before disconnecting it was a struggle if I left the loader in the sun.

This thread http://www.tractorbynet.com/forums/hydraulics/150149-trouble-connecting-skid-steer-quick.html covers the problem and has a link to a previous thread where I show pictures of how to use a caulking gun to force a recalcitrant set of hydraulic connectors together.

Jake has it exactly right. I have one male and one female connector on my lines so I use one of each, but it works the same if you need two males or two females.

The skid-steer typ flat faced connectors I have are notoriously difficult to connect if there is any residual pressure in the lines, but it works with any style connector.

...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.

The only times I had this problem, FEL (or BH) were R&R-ed outside...soooo, now I only R&R them in the barn. No more problem.

On my 3520 I have the same problem. I always move the joystick after the tractor is off before I hook up to relieve any pressure in the system. Most of the time they will go ahead and hook up with some extra force pushing them in. If the pressure in the lines is too much, I will bump the nipple on the connector against a solid place on the front axle housing to release the pressure. Always with gloves on. I will have it in my fist barely sticking out so the glove covers any spray of fluid. Unless it is alot of pressure, there is just a little bit of spray that comes out and it hooks right up.

I have the 724 loader on my L3830. The manual will tell you that after you get the loader on to its supports and uncoupled from its cradle you need to move the joy stick in all the directions to release the pressure in the lines. I found this out the hard way. Only then do you uncouple the quick disconnects and plug them. I guess excessive heating of the lines in the sun could do it too, though I never experienced that problem. Hope all this advice helps. Mike

I made the same comment above. However it would help with tractor off before doing that .

Wrap a rag around the end of the male tip and press it down into a can or bucket to relieve pressure.
