should I replace these hoses?

[Discount Hydraulic Hose]

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 "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.

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

X 2. :thumbsup:

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?

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:

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.
