should I replace these hoses?

[nimblemotors]

They have the outer covering falling off, is that OK, or does it mean they will be going bad soon? or can I just "recover" them?
thanks, jack

If the hose itself is in good condition (no cracking or scaring) you can purchase new fabric covers for them or there is a metal spiral material that is also available. The reasons for a cover would be to reduce any damage caused by weather conditions (i.e.: sunlight, cold, rain). The spiral material also helps to reduce any pinching or scuffing. The fabric material is cheap but the spiral is really expensive. I have been buying my replacement hoses from Discount Hydraulics .com.

I would go ahead and order new hoses, and replace when they finally leak or burst. That is the outer covering that has cracked, and was protecting the rubber, fabric and wire from the elements.

I agree totally in regards to all your advice.

I think Billy means DiscountHydraulicHose.com

Looking at the photo, I am surprised your hoses haven't leaked already. I have seen some messed up hoses before, but I've never seen any with this much damage. The outer cover looks like it's almost completely crumbled and separated from the steel wire.

I would replace those before they blow out and spray hot oil on you or someone else. If you are going to order new ones you might as well go ahead and install them. Instead of waiting for a failure. No sense in new hoses sitting in the barn collecting dust. Not trying to step on any toes just my 2 cents.

You can certainly tell they did not install them properly and have the corrrect fittings.

The outer sheath is the inidicator for hose health essentially as a two wire braid hose has greater tolrance for bending and movement WHEN the hose is plumbed correctly and routed correctly with the correct fitting adapters.

They installed straight fittings instead of 45 degree fittings exiting the valve body which is why the hose outer carcass has failed due to excessive flexing/bending.

The hose sheathing material and the spiral spring wrapping is used to prevent the premature wear of the outer sheath to prevent premature failure of the hose.

My thoughts would be since they controll the loader i would replace them if there is ANY signs of wear, considering the amount of time that loader is in the air when your around it. Hoses are cheaper then broken bones or death!!!

Thanks for you feedback. This TLB has sat outside for many years.
Almost all of the hoses look like these, except the few replaced by the previous owner, who got it almost free, did bare minimum to get it working before reselling it. He did buy new rear tires for it. It was very inexpensive, so expected to fix many things,
although the more I look, everything needs work/replaced..

So the hoses are not really "worn", but the covering has been shot from being outside. Does that change anything?

Also, other suggestions on where to buy the hoses? The discount place doesn't seem to sell pre-made hoses. Should I buy a crimp tool and make them myself? If need to replace 20 of them, and its cheaper to make my own, sounds like that is a good idea if the tools are not hard to use. Use to make them decades ago when I worked at CAT dealership..

If the covering is gone, they will eventually rust and burst when you least expect it.

It will depend on what you find.

You could make your own with bulk hose and replaceable fitting.

Try searching around this web site.

If the "Discount place" you're referring to is DiscountHydraulicHose.com, we do offer a hose assembly service. Contact us with your specifications, and we'll give you a quote. If it's only a few hoses, you can order the hose and fittings from our web site, and use order comments to tell us how to put them together for you. There will be an assembly fee of $10 added to each hose. $12 if your hose is longer than 15 feet.

A new hose crimper with a few sets of dies will set you back about $2K or more. We did some calculations a while back and determined that our entry level D100H crimper would pay for itself after about 100 hose assemblies. If you are interested in going this route, we have an excellent video online that demonstrates how our crimpers operate.

If you have any questions, please call 800-535-1302.

There are just too many hoses on this TLB to replace them all.
But I do think I should recover them at least.

I'm confused about what kind of fittings are used for the hoses and the hardlines. There are some JIC and a lot of Pipe. The hoses seem to use Pipe?
I'd like to create some new hardlines to replace some hoses,
I haven't seen any good info on how I can do that, do all the hardlines use JIC flare fittings?

 

[J_J]

If you are using the unit as earning potential, I would replace the worst ones first.

Unless you are having trouble with leaking hoses, replace them as they leak or burst. Look for the rusty steel first and replace as needed.

Just replace them as time /money permits.

The pictures show JIC on both steel and hose lines.

Most of the hose ends in the picture seem to be female swivels. That usually means JIC 37 degree flare, but you can't be 100% sure without disconnecting the hoses and examining the connections. The JIC male fitting has a straight thread and a protruding cone (37 degrees) which fits into a recessed cone in the female. To identify the size you need, measure the threads and compare with the size charts here.

thanks jj. here is an example of what is all over this TLB.
I would like to replace the hardline with one that isn't bent up, and the hose that is the right length and doesn't use adapters, and rubs and sticks out..

To confirm, the hose to use would be 1/2in ID, JIC fittings, something like this one:
https://www.surpluscenter.com/item.asp?item=940-2218&catname=hydraulic

To make the hardline, I can use steel tubing 5/8 OD, like this?

Note also that the cylinder is only attached to one tab.
I think I can fix this if I use a pin that goes through both tabs and the cylinder.

I appreciate all the help.

Look through the Internet about how to install and route hyd lines and hoses. Even straight runs should have a small bend in the line. Watch out for the flexibility of hyd hose.

Secure the hoses/lines so they don't flop around.

At high wear points, use a sleeve of some kind for hose protection.

We don't stock tubing, so my knowledge is somewhat limited in that area. I just want to point out that tubing your referenced in your link is "Not Flareable" according to McMaster Carr's product description.

The tubing in your photo is clearly flared and connected with a JIC 37ｰ flare connection. If you plan to use the same connection again, you should definitely use tubing that you can flare.

 

[nimblemotors]

yep, and it also isn't rated for 2000lbs of pressure.
Looks like I need seamless tubing for flaring. But the seamless 5/8 OD tubing isn't rated for 2000lbs either. They have 1/2 OD tubing .065 rated at 2500lbs. But its smaller than what is on it currently. So this would mean adapter fittings too.

Assuming you're going to replace the tubing and hose at the same time, you can go one of two ways. You can a JIC union (male x male) adapter to connect the flared tubing with a female JIC hose end -OR- you can skip the adapter and put a male JIC fitting on the end of the hose that connects to the tubing.

Either way, you'll also need new tube nuts and tube sleeves for the 1/2" tubing.
