I have a 666 with a hydraulic problem, I'm not really sure what's going on. Behind the battery, there is a large hydraulic hose that connects to 2 pipes, about 7/8in - 1in diameter. It runs vertically from the top of the transmission up toward the steering wheel. I imagine it feeds oil to the steering wheel and components up there. Under normal driving conditions, it works fine. However, the problem I have is that when you actuate the hydraulic remote (to operate an implement), this hose blows off the pipe and shoots gallons of oil everywhere. I've tried several different hose clamps, stronger hoses, etc, and nothing holds it together. Any help?

If they are high pressure lines, clamps won't work, you will need to get high pressure lines made.
These are unlike the lines to the cooler which are not high pressure and hose clamps can be used for that type of application.

This is what im working with. Im suspecting that this hose was a hack replacement at soeme point, but it worked for a long time. Now it won't stay connected. Even with those heavy clamps, it blows off when you operate the remote.

Hose clamps shouldn't be used on hydraulic hose. See if there's pipe threads on your barbed fittings where your hoses are connected. I would get rid of those 3/4 hoses and barbed fittings. Install 3/4 pipe to tube fittings and use 3/4 double braided hydraulic hoses with swivel nuts. You need to measure the hose length and allow some extra. Take your barbed fittings along so you get the correct pipe size on your tube fittings. Make a note where your hoses were installed. I would use a light of pipe dope like Gasoila Soft-Set on the pipe threads. Hal
Here is what I am seeing in your picture . You have a hydrostatic drive tractor and that is the line coming from the right side of tractor, main hydraulic pump, and going to the flow divider valve. It is originally made with a section of hose then pipe, then hose to pipe again. It is indeed high pressure and I cannot for the life of me understand how that hose with clamps ever worked. I have to take your word for it that it did but it is not at all correct. You need to get a braided hydraulic hose made up to fit with proper ends or get a whole new line hose assembly.
That's what I thought too. It only blows out when the remotes are used (to raise and lower an external implement) which isnt often. This tractor is mainly used for towing and carrying using the 3-point hitch. However, if that's a main feed line, you would think that would have been a problem a long time ago.
Do you know if that's a stock part that I can order from a supplier, or if it's a custom hose I would have to have made up?

You also need to purchase flared tube fittings that will fit where your old barb fittings are installed. They may be pipe thread so take one along. If you're using 3/4 hose I would have swivel nuts installed on the hose. If you have a manual for your tractor it may give the hydraulic pressure for your tractor. I would have the hose or hoses made.
Be sure to measure the length. Hal
