Hydraulic line replacement

[dtd24]

Well, this is the first time my JD1070 has needed a part since I have owned it. I was doing some work to my driveway to save it from the great ground thaw. My flexible curl cylinder hose on the supply side busted on the left side from dry rot. Not having any knowledge with hydraulics, I figured I should ask how to fix it. Do I just remove and bring to napa? Do I have to drain for pressure relief? I will replace both left and right, because the right has sign of dry rot in same spot where hose takes a bend before connection. The metal end on the right is bent, will napa have replacement end?

I'll have to wash her down after fixing, the hose sprayed fluid all over her and some on me .

Thanks Guys

NAPA should have everything, if not you can order from DiscountHydraulicHose.com hose and have NAPA do the crimp. You should try to find out why the original failed and correct it. It's always dry rot at first glance but the hose contains a one or two steel wire braid and just the over cover is rotted. Did the wires rust or fatigue from flexing?

Shaley,
The tractor is a 98, so I do believe it is just dry rot. The hose does take a pretty sharp bend before the connection, so I may try to change that with the length of the new one. That is where the hole opened up, right on the bend.

Your dealer would be the place to get original (and pressure tested) replacement. Typically I do not have the patience and just take it to my locally auto parts store to get a replacement made. Note that many of these auto parts outlets are manned by untrained personnel with no means to pressure check the new line after assembly, so please be careful if go this route.

Hydraulic hoses are very strong in the very nature of their construction however as they say nothing lasts forever. Part of the preventive maintenance should be to check all flex lines, when they become brittle to the touch it is time for them to be gone.

Measure the hose length, identify the end fittings and call Discount Hydraulic Hose and order another one. Make sure you get at least 2-wire 4000 psi hose. Accept nothing less. If you have a dealer nearby or a local hydraulic shop or NAPA store nearby they should be able tho fix you up too, but will probably cost more.

Most people around here just take the old one into a hydraulic shop and say I need a GOOD quality hose just like this one. I make them use Gates hose instead of import.
The dealers seem to do the same thing unless you want to wait a day or so for a factory one to come in.

As the other poster said.. a new hose probably didn't 'dry rot' even if the rubber looks bad on it.

I got a 1957 tractor with 3 vintage hoses on it. ( the specific banjo ends on it havn't been around for -decades-.. so i know they are vintage. they are dry and cracked, and the metal underneath is fine..... 1998? those are 'new' hoses. I have hoses from 98 on my batwing mower.. dray and cracked.. and don't leak...

Flexing on the other hand may have caused it to blow.. etc.

Or cheap hoses...
My old IH 1968 vintage 2050 loader has the origional hoses on the loader, look horrible but will still lift a ton or so. Their replacement is part of this years refurbishment though, some of the swivel fittings dribble a bit.

I have blown all four of my curl cylinder hoses (all identical, 18" long). Everyone of them blew where the fitting was crimped onto the hose. Everyone was also a bath for my loader, tractor, and me. I went to my dealer and he made them on the spot for less than $20 each with new swivel fittings and 2-wire, 4000 psi hose.

After the second hose blew, I just had three made. I put one on the loader and just waited. Sure enough the other two eventually blew and I had a replacement on hand. If one of yours blew, I'd at least get two and keep a spare handy.

Yeah, Im gonna replace both curl hoses. Hated the hydraulic bath!!

The hydraulic hoses are generally referred to as "flex hoses". When they no longer flex it is an indicator that the hose has reached the end of its useful life. In addition to the hassle of having to stop what you are doing to acquire a new hose, cleaning up the mess that resulted from the failure you are subjecting your hydraulic system to contamination which can result from the interior deterioration of the hose assembly.
My time available to spend on projects is limited so I attempt to minimize my down time by optimizing my preventive maintenance.

A hydraulic flex line that will not flex is a failure waiting to happen.

I am resurrecting this thread because I am having a similar issue and would like some clarification. The rubber on my loader curl lines is also cracking. From what I understand in this thread is that this does not mean they are about ready to blow but that I need to check to see what the hoses look like below the cracking rubber. Is this correct or should I change them?

 

[Soundguy]

The wire is what holds the pressure. if the wires are intact and not frayed or rusted.. then the hose is not yet ready to leak. no doubt that once the outter cover is gone.. the hose will be more prone to decay and damage.. etc..

Exactly what soundguy said...
That means you either have to keep a close eye on them or replace them, because you might not be able to tell how they are reacting to atmosphere ... rust, decay damage etc. If it was me, I would replace them in the near future just for peace of mind. On the other hand, you could leave them on and just wait for failure ... because you might still get years of use before that happens.

Then again, I had a loader hose pop on me that looked ok. No cracks or checks. Lifted the loader up and hit the limit and pop! Scared the schnitzel out of me. That was an original 1963 hose, so I guess it was time. Had all new ones made.
