Hydraulic hose for lift cylinder stuck - any tips?

[faultyEnterprise2]

I'm trying to replace the hydraulic hose for the lift cylinder on my s300, but the lower fitting is seized tight. I have decent access with wrenches (I removed the battery to give myself easy access), but it is stuck tight.

I just ordered a set of crowfoot wrenches, but those won't be here for a few days.

The part number for the hose (in case you need to know) is 7102337.

Am I doing something wrong here? Seems like it shouldn't be so difficult to remove. (Picture is of the hoses on the other side - same hoses, but i don't have any pictures of the bad side.)

over the years I have made many special wrenches but cutting, bending and welding, wrenches are cheap

Considering how difficult these line fittings can be to remove, use this exact style or type of crows foot wrench. I have used this type for many years and they work well they don't strip the line nut. Hope this helps!

What does the other end of the hose thread into? Or is it the same as the picture shows? Is it in cast steel valve or does it attach the same way as the picture shows. Soak it with some penetrant. If it is into a threaded casting of some type you could heat it but not much. Can you get a picture of the other end?

Not sure which hose you are trying to turn. Steel or flex?

It should be the steel while holding the flex in place.

You may want to put some penetrating oil at the base of the "nut" on the steel hose. They sometimes get rusty in there and will not turn easily.

If your trying to remove the line from the cylinder end try some penetrating oil there as well. If the hose thread directly into the cyl. casting it maybe frozen rust etc. If that fails use some heat but not alot and protect the cylinder with wet cold rags. Somtimes just a bit of heat will due the trick. If that is not the spot and you have crows feet coming I hope you got the line type as shown above. You may have to plan on a new hose unless this comes free. Be ready with that also. I have had to use pipe wrenches but not often. If it doesn't come free can you get it out with the hose attached to it? More work but maybe the less stressfull way. Good luck and I hope it doesn't break off in the cylinder. If that is the tight spot.

You cannot show the bad side in a picture? Not visible or? That may help get a better answer. If possible. While your waiting for crowes feet soak the fitting with good penetrating oil. If you can spray it and spray it do that. Worse case is pull the cyl. with the hose attached to gain access. I know it's not always possible. Good Luck! Hey keep the group posted on the results.
