JD 350B Steel Hydraulic line

Post by 1CardShort » Tue Jun 11, 2019 8:00 am

First-time poster, long-term viewer. I appreciate all of the help I have received by following other posts!!!

I have a 1971 350B with a leaking steel hydraulic line under the battery box where the 4 lines are clamped down. It appears to have rusted out under the clamp. I tried to braze it but that doesn't hold-up under pressure. I have a parts manual but can't seem to find anything that looks like what I can see under the seat. It's the line furthest to the outside where the rubber lines go to the blade. Can anyone provide me with a part number for a replacement?

I am guessing you are looking at a hard copy parts catalog, does it have the actual blade hydraulic system in it? The on line parts catalog needs the blade model to find the hydraulic components, as the 350B parts catalog is for only the bare crawler. Saying you have 4 lines together, under the seat, sounds like you are looking at the left side of a #6305 inside, 6-way blade. The on line parts catalog shows the lift and tilt line and hoses in separate illustrations so you don't see 4 together (lift and angle on the left side). If my thoughts on what you have are right, it looks like you are talking about item 6 in the link below. Don't order just on my choice here. You need to confirm for yourself which end of the cylinder yours goes to and, I would suggest having your dealer"s part person see if they come up with the same one so you don't end up with a tube you don't want and have to pay restocking or such. (Replacing it with a hose might be and option, many steel tubes/lines have been over the years. I see a price of over $150.00 for it.)

I have a 450B.
I had some damaged hard lines. Maybe I was lucky but, I was able to braze one section- used flux and built up a layer.
Also, had some crushed sections I was able to splice in replacement tube.
If yours is leaking on a straight section- maybe cut out that section?
I cleaned lines with solvent then acetone first.

Thanks Jim B. The line in question is on the left side and is angle the blade. The inside 2 lines are for the lift and the outside 2 are for the angle. I like the idea of getting a hose made and will look into that.

Labparamour: I sanded the tube down to get to clean steel and used flux but did not use any solvent. May give that a try before I replace it with either a new steel tube or a hose.

I would replace the hard line with a flexible hose. Maybe even run it all the way to the cylinder.

You could also cut and slip a compression fitting on and make the needed repair.

If you didn't do this, you can click on the green arrow to the right of the page title after you open the link. That will bring up the angling lines page and you can get the part numbers for the angle circuit components.

Thanks Jason, I'll check the cost of a hose vs. metal replacement. I found the metal line for about $100.

Thanks, again, Jim. I figured that out and it looks like the part # is AU13883. Found it online for about $100. Will compare that to the cost of a hose and decide from there.

My local hydraulic shop would be about $60 for a 8' hose with fittings.

Yeah they seem to do us right.

I have a hydraulic press to do my own compression fittings, but find it easier to take my hoses to them and have them recrimped. Most of the time, I can't buy fittings cheap enough (that I trust) to justify doing my own work.

I do like to buy two piece fittings so I can cut away the crimped piece and reuse the threaded/ barbed piece when desired. I have reused some fittings 3-4 times. Most of the time it's the hose that lays down not the fittings.

Not to mention those hydraulic guys know their business better than I ever will. They can usually recommend types of fittings I never knew existed. I think their real money is in rebuilding hydraulic pumps, motors, and cylinders.

I learned years ago there is little money in sales but lots in service.
