Hydraulic fittings hard to connect/disconnect.

Original Post

I have a 2038r with the mid scvs. I use these to connect my FEL and in the winter my front snowblower. The hydraulic lines are very difficult to connect and/or disconnect. Maybe I'm just getting old and weak but to connect or disconnect these lines are a real difficult process. I'm fully aware of the process to release the pressure on the lines by shutting off the tractor and moving stick around, so this is not the problem. It takes a lot of effort to get them in or out. I also have a backhoe and never have a problem connecting or disconnecting those couplings.

Just wondering if anyone else had this issue and what you did/do to make the coupling/decoupling process easier.

Tap the male poppet on the implement line to relieve the pressure on it. Heat will cause pressure to build on disconnected implements.

Just shutting off the engine does not release the pressure. After shutting down, move the scv around, and then connect.

If the FEL hydraulic lines are connected to each other while in storage, there should be no residual pressure in that implement, but if they are not, there may still be pressure on one side, causing difficult connect.

After disconnecting from the tractor, connect the ends together on the implement to relieve pressure.

The loader itself has all male fittings that can't be connected together.

If the grapple has a male & female fitting then connecting them does help prevent pressure buildup.

Keep an old “used up” hammer with a rubber cane tip on the end of each close by each piece of equipment with Hydraulics to tap the poppet with and release the pressure if it should happen to build up or I forget to swivel the stick around.

Wash the connectors and air blow them to clear away any grit and still can't seem to get the coupler pushed far enough to release by hand. I have taken to using an open end wrench that just fits to help push the coupler in.

Using pliers to get them connected is also an option.

Pressure build up is not the problem. It's just difficult to get the couplings in or out.

Hose down the connections with WD-40. A very little bit of dirt or corrosion under the sleeve can make connection difficult as the sleeve hangs up just enough so the balls can't fully retract.

On the bottom two connectors, the end of the plastic caps was behind the metal clip that you push in, I cut them off and haven't had a problem since.

They have gotten harder to do as the engineers tried to make them not leak, and as I age and my arthritic hands get worse they get to be more of a challenge. Someone needs to design some with bigger grips to help us older people out!

Replace the couplers with new ones.

Male female connectors by definition will allow the given cylinder to collapse or expand in whatever direction gravity will ask for.

Pur a rag over the end of the male coupler, smack it on a 2x4. Relieves the pressure, makes connection much easier.

Switching to Stucci couplers is a solution. They will couple easily under any condition. They pull together with screw threads.

The collars on the valve where the hoses connect won't push in far enough to make a clean release.

The hydraulic connectors on the grapple hoses may be worn and are the problem.

Buy quick couplers from Northern Hydraulics, and they’ve made a huge difference. The ones I picked up are easier to handle and seem to connect more smoothly, even if there’s a little residual pressure in the lines.

Warm up the connections slightly (carefully, with a hair dryer) when it was really cold.
