Backhoe Lines after removal?

[bg71361]

I have a Ford 1910 with what I believe is a Bradco Conversion. It has a loader and backhoe, plus a custom nose. I will be removing the backhoe this weekend and have a question on the hydraulic lines. There are two lines, once disconnected, should the be hooked together on the tractor side after removal to prevent dead heading of the pump?

Appreciate any help!

More than likely, yes the lines should be connected together. I can't speak for that tractor but on my JD the power beyond circuit must flow free to avoid dead-heading. Any valve connected to it must be open-center.

FYI, I also hook the backhoe hoses together, just to avoid contamination.

As Rob said, they should be connected together, the full flow of the hydraulic pump probably flows through these lines.

Take time to inspect the lines. One is the supply line and is the full hydraulic pressure. The other is the return line. You want to have the return line looped on the hoe and the pressure line looped on the tractor.

That way you won't rupture the line on the tractor and spray hydraulic fluid all over everything and everywhere.

You might be lucky and both are pressure rated, but typically not.

As RobS said, hook your backhoe hoses together to keep the fittings clean. However, let the pressure out before you do that. After you unhook the hoe with WARM fluid in the hoses, release the pressure on the male end and let as much fluid dribble out as possible (1-2 teaspoons). Now hook your two hoe hoses together.

If not, you can run into the situation where the hoses are completely full of cold fluid. The hoses heat up in the sun and the pressure gets to the point where it is almost impossible to connect the hoses to the tractor. That happened to me before and the only way to release the pressure was to hit the very tip of the male end with a hammer. Fluid shot out everywhere under pressure. But, the problem was solved. The hoses then hooked up to the tractor with very little hand strength needed like they should.

The black hoses get hot in the sun and warm the fluid inside the hose. It tries to expand. If the hose is already 100% full, you will get pressure build up. If you have left a little air space inside the hose by burping it, you can prevent that. The fluid has room to expand. It only takes a little air space.


This advice would also apply to log splitters or other items hooked to the rear.

If you only have 2 hoses out to the hoe, one is supply, one is return. Chances are the pressure line comes directly from the pump. If not, it goes from the pump, thru an open center valve, then to the hoe. If you hook them together, fluid just flows from the tank, to the pump, thru the lines, and back to the tank. There will be very little pressure as there is almost no restriction. Hook them together and have a nice day.

Thanks everyone for there input!! That is what I thought but I figured I better check since this will be the first time the hoe will be off. I guess I will take this opportunity to put some quick connects on.

Thanks again!
