450C crawler bucket cylinder steel line AT31954

Post by skunk237 » Mon Feb 03, 2020 3:28 pm

My 450 C loader developed a leak in the bucket cylinder line on the right side near where the line turns to go down the cylinder. I got a small hairline crack which shoot hydraulic out when I curl the bucket up. I cannot fine a line anywhere. JD says the line is obsolete, part number AT31954. My machine is a 1982, The crack is about an inch long. Anyone have an idea how to repair or where to buy a new steel line?

Thanks much.

God Bless America.

Silver solder to fix it. That is the process used to attach the swivels to the ends of the solid pipes. I don’t have a used resource.
Best regards, Bruce

Bruce has a good, commonly used fix. I've also seen brazing, TIG, or MIG used, depending on processes available and skill levels. As for getting a new tube, one way would be if you can find an industrial hydraulic shop that deals in process tubing such as used in mills, power plants, etc.; they should be able to get the right tubing and ends to duplicate your tube. Sometimes hoses have been used to replace tubes, routing can be a pain. Good luck with it.

People/companies that build industrial hydraulic power units would be able to duplicate the line. Where are you located?

Take it off, clean it up, bronze it or silver solder.

Thanks much guys. I have some brazing rod and will check out the silver solder method. I can stick weld.

You guys always have the answers. I am so glad I found this message board and so many are willing to help a novice.

Have a great day and God Bless.
