Replacing all hydraulics hoses with Cloth protective covering?

Hey guys. So I'm nearing the end of re packing all my hydraulic cylinders and almost all the hoses on this 580 Super K are in bad shape. At the moment I got one that is leaking I need to replace that goes from the backhoe control valve to the boom. This area has prob 6 or more hoses running all together at the swing pivot area of the hoe. I just yesterday got two hydraulic hoses made up at napa for the extendahoe and had those two hoses cloth covered. The look real nice. The cloth covering was crimped underneath the crimp fitting on each end and not zip tied or some ****.

Question for everyone: Is there anything wrong with replacing all my hoses with this cloth covering included? I don't see a issue, except maybe the extra cost... In my opinion, all these hoses have shorter lifespans due to aging in the sun, so protecting them with the cloth cover sounds like a excellent idea! Thanks for the opinions!

Sounds like a good idea. As long as the cloth don't cause the hoses to get snagged on anything.

I've never seen it crimped on. It is usually just added loose as an abrasion resistance measure but it may keep the sun from damaging too.

I have sworn off cheap foreign hoses and just have our local Carquest make Gates hoses for me now. I was getting all my hoses made at a shop that specializes in anything hose but some of the Italian stuff they sold me cracked and split in 3 years. They have sold me three different brands of hose and I think the ones that didn't hold up were the only ones made in Italy so maybe the others will last longer.

There is a protective sleeve available now for hydraulic hoses. It is designed to contain the oil in case of a burst hose and not allow it spray everywhere. It is not designed to function as extra abrasion resistance. Usually used in any compartment where there is heat present that could ignite the oil spray from a burst hose. The protective sleeve is crimped to the end fittings of the hose.

Here’s a couple pics of the fittings and the crimped in cover.

I make sure that the hose is safe in all positions. Sometimes it takes a few cycles and on and off the seat to really look at things, and then a really small tweak at the fitting. It is worth it. I also use the big zip ties in figure 8 standoff between pesky hoses that will not leave each other alone. We do that in aviation, and also do the wedge and silicone bed method, where you see the bad spot, put a big dob of silicone between and then add a wood wedge that stays overnight. Take the wedge out the next day and you have a custom bumper standoff.
Monitor it and see how it holds up.

Never have seen the cover crimped with the hose ... I like that, if the hose doesn't blow off or leak. The covers I got were held at the fitting with zip ties. When the cloth shrank in the weather, they pulled back exposing the hose. :mad:

Skyking1 ... good tips , thanks

That looks like the protective sheath I’ve seen, but with a difference. On the hoses I have seen the protective sleeve is crimped on top of the end fitting after the hose has been manufactured. That way if the end fitting crimp lets go the sleeve is still there to contain the oil flow. On the hose in the photo if the hose separates at the end fitting it will still blow oil everywhere.

The stuff I've used was made of kevlar and did provide abrasion resistance. I would never include the material inside the crimp on fitting. The fittings are made to clamp onto the inside mandril to a specified depth. Anything more and you risk damaging the inside liner of the hose or the possibility of the hose failing at the crimp. We always zip tied the stuff at the small end of the fitting just past the crimp if possible. The kevlar cover won't contain the oil that leaks out. It will cut down the spray atomization possibly preventing a fire.

The sheathing that I use to buy had a quantity of narrow width band clamps included. When properly clamped in place the OD of the clamp (usually) didn't prevent the hose from going back into tight places. But you had to be aware of the position of the fitting when installing the clamp, even though they were pretty small they could interfere in tight areas. This was before the days of cheap high strength zip ties. I don't ever recall seeing it placed inside the sleeve before crimping.

Mine aren't crimped and are made of fire hose with zip ties on the ends. I expect they assists in delaying sun damage and would delay any spray if they break.

@John C. , I had one of those bad cramps from a Cat dealer. Had a leaky hoe pack hose, drove just a couple minutes over to NC in the valley. The parts guy said hey they showed me how to do this the other day!
He handed me over the hose, I drove back up the hill in Kent put it on. I pushed the pedal the hose blew off immediately and there was this perfect outline of a dry spot where this guy was up in the seat.
I was completely covered as was the back of the back hoe.
On inspection I could see that he got the hose about a quarter inch into the fitting stepped on the pedal and called it good!

Having the Kevlar protection on the extenda hoe hoses is a good move as for the rest like skyking1 said make sure the rest aren't rubbing and they'll last for years.

Only thing that should be under the fitting crimp should be the hose. If you don't like the zip tie method to hold on the hose cover get an oetiker or SUR&R one ear hose clamp kit and crimp em over the fittings.

Maybe they only inserted the cover a little bit into the fitting.

I have sworn off cheap foreign hoses and just have our local Carquest make Gates hoses for me now. I was getting all my hoses made at a shop that specializes in anything hose but some of the Italian stuff they sold me cracked and split in 3 years. They have sold me three different brands of hose and I think the ones that didn't hold up were the only ones made in Italy so maybe the others will last longer.

I agree on the Gates hoses. Our local NAPA went to Weatherhead hose years ago and the outer rubber layer was spiral wrapped on and within no time in the sun the rubber would start to crack along the joints of the spiral and let rain water in then the hose would be bad and a lot of the hoses that were on equipment that sat outside wouldn't last much longer than a year. Any way I always felt like the cloth covering would help defend the rubber from the sun and I'm sure it will but it ultimately starts with a quality hose.

The cover is NOT supposed to be in the crimp and I wouldn't trust that for ****. That's what happens when you have someone that doesn't have experience in building hoses....build hoses. The crimps are done to a specific measurement and that cover material has thrown that out of whack. It wont last long.
