New hoses and fittings for my 002a

[metalworker393]

Hello and how are you all doing. So I have a question for you all. Planning on doing some maintenance on my 002a. I bought the spin on filters and brackets for the fuel system . Have to get a piece of plate to mount them on and then proceed with that.
Well, it's getting time where I want to make up all new hoses. When I went to the local hydraulic shop and had a hose made, it was pretty pricey ,for 1 hose with crimped fittings.
How do you guys feel about using brass barb x FJIC swivel fittings instead of the crimp on ?
I am looking at a 50' roll of Parker Hannifin #213 hose.
If this is suitable, or if some of have used this I can buy enough fittings for my 2a machine, the 2a machine I lent to my cousin and if I get my 3a machine making power again I'll do that one too.
Let me know what you guys think. Thanks, metalworker393

You have discovered the biggest price gouging scheme in equipment supply today.
The price for materials, assembly labor, isn't even close to the sky high prices they charge for hydraulic hoses.
Your lucky it was only a small hose.
Last one I had made was almost $400, for one 3 foot hose.

I will replace my hoses on my MEP-002A on an as needed basis.
Have other generators that I can use if a hose breaks while in test mode or actual use.

I personally wouldn't use a brass bard with those fittings.
On other things, yes, but not on a 002A or any other generator.
Just too much vibration on the 002A
That's just me and my personal preference.

It's your set, do as you wish.

I have friends who use the screw on hydraulic hose fittings, but for me, that's always been a much more expensive solution. YMMV.

All the best, 2PbFeet

If it ain't leekin, don't fool with it. Having said that, With hoses, you get what you pay for. If it was my machine and I was living in, say, Florida, I would be saving money by drinking less beer and spending more on hoses.

Most people don't know, but the fuel line fittings on an 002/003 are not crimped fittings, they are reusable threaded fittings that work the same as Aeroquip fittings etc. You hold the outer shell and turn the inner ( end ) fitting, left hand thread IIRC.
The center portion will unscrew out of the hose and then the outer shell is unscrewed off the OD of the hose.
The trick is using replacement hose with a similar OD so everything fits together correctly.
Regular 5/15" fuel line may be too small, you may need to use power steering return line of transmission cooler line, or fuel injection hose, all of which usually have 2 layers of nylon braid and a larger OD that single layer fuel line.
Not sure if all vintage machines are the same, but I just did this in an 86 Libby.

If assembled correctly, The OEM hose is bomb proof. The hose material is super good. Long lasting. the fittings, well, like I said, if assembled correctly, they are top of the line. I NEVER saw one cracked or unserviceable, unless someone cross threaded it.

 

[metalworker393]

I hear what your saying Guyfang. But 1 of my machine a hose by the filter assembly was rock hard and cracked. It leaked pretty good. Who knows what that machine was subjected to .
I was looking at reusable fittings that screw together. The part that hoe's on the hose had a female left hand thread inside the sleeve and the othend you screw a right handed end into the fitting . As it screws in the end of the fitting goes into the hose to keep it sealed tight.
We used those fittings on some machines at a former job I had . I might buy them, I believe the supplier even listed hoses that would be correct for the fitting .

 

[Guyfang]

Then look in the -24P for the fittings. They are the type that screw into the hose. Then you need the right kind of hose. They are easy to make, or at least when you have done it a few times.

Hey now instead of compromising my beer budget and needing another hose i just bought another MEP

According to the parts manual the hose is Aeroquip 303-5. The fittings are reusable as others have said. The hose is not cheap but I have been trying to find a different hose with same diameters and have not been successful. Best I have found is $10/ft, Not sure how many feet I need but plan to measure and order some soon.

 

[Ray70]

At $10 a foot for the hose you may want to consider just buying custom made hydraulic lines on line. The assembly cost at the place I use is $10 per hose and material cost is only about $6-$10 per hose for the -5 fuel lines, so pre made hoses usually end up at around $15-$20 each and shipping isn't bad if you buy a bunch at once. Only warning is to make them a couple inches longer on the short hoses because the crimp on fittings are a little longer, making the hoses unable to bend as sharply in some cases.
Another option might be to use a good aux. fuel line if you have an extra. Chop it up into pieces.
I have quite a few of them on my shelf and could see if I have a nice soft one?

 

[DanCHerman]

Ray70 where do you get your hoses online?
I just had one made to go between the first and second fuel pump on an 003a that cost me $61 at Pacific Rubber.
I am considering doing all the fuel lines on both 003a's that I just picked up, so was looking for a lower cost option.

$10/ft is expensive but if you consider how often you need to replace the hoses it is not a big deal, IMHO. I have not measured yet but I would think 20-25 feet would be more than enough to replace them all. $250 in hose to replace them all seems like it is not out of the question. By the time you pay to have all new hoses made you will be in that ball park.

I have a hose place I get hydraulic hoses made for cheap money. I have them made for my backhoe. He does them for me cash. I had four four foot hoses made for the hoe and the Caterpillar price was over $300/ea. He charged me $125 for all 4.

Just my two cents.....

Something to remember here. These are -5 fittings. NOT a normally stocked size these days. The obscurity bakes them a bit spicier on the wallet.

-5 has been the bane of my wallet... I've got 3 hydraulic tractors that all run almost exclusivly -5. For anything I could I swapped down to -4, and if it needed flow I went -6. It was cheaper to change fittings to go larger/smaller than it was to get a -5 hose when I could even find a shop that had the -5 on hand...

Parker Push Lok hose is absolutely suitable for most fuel supply, return, and lube oil applications on engine. Look for the Push Lok Plus HT 836 series. It's borderline for coolant applications if you're running your engine continuously but likely acceptable for most applications. Push Lok 807 is ideal for coolant but may not be necessary.

Electro Motive dangles all of their fuel and oil pressure transducers from a 2 inch piece of 836 hose with an external spring over the hose. They have a lot of trust in the stuff. I've got two engines at 10,000 hours with no signs of deterioration.

 

[Toolslinger]

I never thought to look in to the Parker Push Lok hoses for fuels... I've had a Series 801 air hose for years of that type, and it always made me nervous without a clamp, but it has never leaked, or failed...
So I ran over to the Parker catalog and looked up the 836 hose. Yep, rated for diesel, with an asterisk... Asterisk (in very small print) indicates diesel is ok only when used with the HY crimp on fittings.
Well that makes me sad... Pricing on the 82 series push on fittings, and 836 hose isn't too bad to have on hand for emergencies, but just not rated for the application per Parker.
