L35 Front Hydraulics: Metal Lines

[wmurphy]

I have a L35 where the one or both of the supply/return hoses have rusted and are leaking. The leaks are under the radiator location where the supply/return hoses run parallel to each other. I have access to the pump and the top and bottom hoses. However manipulating the metal hoses to remove them is proving difficult.

What is the most straight forward way to remove the hoses?
The bolts securing the Pump bracket are pretty rusted and wanted to round off so I haven't removed them. It really looks like at minimum the pump has to come out. Looking for any advice or tips.

thanks
Will

My best advice, steam clean everything, then spray whatever you need to remove with rust breaking lube and let it sit for days then go to work.
Remove what you need to, to get the parts off and out of the way without forcing anything.

Are these the pipes that run from the front of the tractor to fittings under the seat?

These are the pipes that run from the hydraulic pump in the front (just under the radiator). One comes off the top of the pump and runs back to the filter mounted on the side of the tractor, and the other (smaller diameter) comes of the bottom of the pump and runs basically underneath the tractor to a coupler. The top pipe is larger in diameter (1" or so) and the bottom one is 3/4" in diameter.
For the larger diameter top pipe, the dealer quoted me $560.....

In my experience working on any tubing line and many hydraulic hose lines the use of Flare Nut Wrenches works better than a standard open end wrench. Access with flare wrenches is the biggest issue.
