B7800 hydrolic problem

[Nub]

I recently purchased a B7800 with a front loader to help me move snow. It worked well, but I soon learned a snowblower was going to work better for my needs. When the snow cleared I went to reinstall the loader. The hydrolic line would not reconnect. I talked to a "friend" and he told me to hit the plunger in the hose to release the pressure. Well it relieved the pressure, but when I put it back on the connector, the fluid came streaming. I think I damaged the hose end connector. My question: is the line under constatnt pressure or can I remove it to replace it without damaging the system? Also I can not locate the filler port for the hydrolic fluid. Any help would be much appreciated!

I'm not familiar with those quick connects. The ones on the tractor will always be under pressure if you have the engine running though. Don't even try to "depressurize" that line when running, it'll make a big mess really quick.

The hydraulic fill is the same one as your transmission. They share a common reservoir.

When you disconnected the loader, did you release the pressure at the valve before you disconnected the hoses.

On my old tractor I would have to do the following procedure.

Drop my stands, shut off the tractor, lower the loader, move both loader valves back and forth to releive pressure.

If I didn't do this, the pressure on the hoses would make them almost impossible to attach.

Hope this helps.

I think this is good advise on any type of hyd. powered equipment. It only takes being injected with oil or fuel one time and somebody else will be working with your tractor and you will be under ground wondering what went wrong.
