Hydraulic Hoses - Check or Replace?

At the start of my reclamation project, one of the hoses powering the tilt cylinder burst. 4 flexible hoses complete this circuit: 2 leading from the chassis to the arm to allow arm rotation and 2 from the arm to the Bobtach cylinder to allow bucket tilt.
One of these hoses has been abraided and another has failed (I cannot see where it has failed, but the oil fountain and the lack of the tilt action were clear indicators that this circuit had issues). Obviously I need to prevent the abrasion, whatever the source, and replace the leaking hose. But, assuming all things are mechanically sound, is it best practice to replace all hoses in a part of a system if one fails. For example, should a motor hose fail, would the average contractor or serious user replace both hoses or just wait for the other to fail after checking its condition?
If common-system hose combined failure is common, then preventative maintenance would imply replacing all lines; if it is not, ad-hoc replacement may be more economical.
Opinions?

(The abraided hose is on the left above my 4th finger's knuckle - I'm pointing simply to have an index marker for re-installing the lines when I start replacing them)

I am a "replace them as they fail" kind of guy, but if they are showing signs of wear, cracks, and/or abrasion, that is a different story. I have a buddy with a hose shop, so I typically get new hose assemblies made with hose that has an integral abrasion sleeving. Hoses that are in close proximity to each other and do a lot of flexing and rubbing, I will install abrasion sleeving on them as an added precaution. FWIW

I have to agree, if it shows signs of wear and cracking, it's possibly time to swap it out, especially if the other burst one is right next to it and access will be a little better when it is out. I get hoses cheap, so if i'm in there, i try and do them both, especially if i needed to remove things to gain access.

That abrasion sleeving is the first time that I've heard of that,I'm glad I clicked on this thread,could you provide a pic when you have the sleeving put on?

I'm a big cheapskate as well. I put the clam bucket on the 873 to try it out and as soon as I touched the switch for the aux a hose burst inside the loader frame. A buddy owns a local parts store and made them up cheaper then the going rate but it was still $70. I did NOT want to do that job twice though.

I'm cheap too and I drive older cars. When I do a job I'll replace both heater or radiator hoses if one bursts just so that I have reliability and don't want to be constantly chasing problems. If one hose burst the others are not likely far behind. I vote for replace.

Zorack - please see a photo below of the abrasion sleeving:

Old hose on left, new hose on right. To be clear, the stuff is expensive (about 1/3 the price of the hydraulic hose itself). But given the price of oil (which leaked out of my machine), plus my time, plus an almost coronary from frustration, I think it is worth it - especially when the lines clearly run against something (like the tilt cylinder lines) and get abraided.

I like the abrasion sleeving on hoses exposed to direct sunlight. It blocks the UV rays from breaking down the rubber and ruining your hoses quicker.

the sleeve pictured is actually classified as fire protection covering , it does give some protection , there is something I like much better , spiral wrap plastic hose protector , I will post a link to a pic as I have never been able to post pics to this site ------------------- in the first pic of the tilt hoses , it looks to me that the tube hold down clamp is missing

This really irritates me. I think you are spot on FishFiles as in all other cases where I've used abrasion protection, the hoses have come with a spiral type binding. I just assumed that the chap selling the stuff was selling the correct item, i.e. that technology had advanced to the point where this stuff was superior.
The protection I normally have used looks like a metal spring wound loosely over the hose. Tends to eat the machine before the hoses die.

Thanks FF. I've bookmarked the spiral hose protectors and will likely be using it soon.

Something to think about on spiral wrap , if you are wrapping a 1/4 hose that is say 6 ft then 6 ft of wrap will do it , but if you are wrapping a 6 ft 1/2 hose it will take more , the larger diameter hose eats up inches quick , so I always get a little more than I need , and the pieces left over come in real handy when you have a hose that rubs in one spot you can use your pieces to cover that spot , it also works well with wiring harnesses -----------------on grapple hoses I wrap both hoses together inside the spiral and it makes it really neat -------------- I tried to find a steering wheel cover for my EZGO Workhorse and couldn't after I wrapped the wheel with spiral a cover fit it tightly , also wrapped the steering coloum with it and it looks good

Thanks Fishfiles! I noticed the site also sold Flexible Neoprene Protective Hose Wrap...wondering if that would be any good for 4" sections...my protective wrap has worn away in few places, especially where hoses thread through knuckle to boom (excavator).

Yeah Melli , it would work well on the hoses thru the articulating boom knuckle , probally beter , but you would have to take the sock tube off first as I would think it would end up being too thick to put it on top the sock ------------------------ I know I must have over 100 ft of the spiral on my shrimp boat and 40 ft on my fishing boat , used it over fuel lines and wiring harnesses , I even have it wrapping the propane hose between the regulator and burner of the crawfish/ shrimp boiling pot ------------ that web site I linked to is not the place where I buy it from , although it looks to be the exact same I don't know if it is , I was just using that site as a reference , the hydraulic hose machine on my truck is AeroQuip and I buy most all of my hydraulic supplies from the local AeroQuip dealer , AeroQuip and Eaton are now combined and the new fittings say Eaton on them --------- AeroQuip is a little more expensive than say Gates or Parker but I think as far as hose and fitting go it is a better quality , if it is good enough for NASCAR and the Space Shuttle it must be OK
