Topic: Making oil lines

[70CB750]

I searched high and low for a shop that would make me SS oil lines - no luck.
Finally I bough $25 worth of 3000 psi hose and done it myself.
To cut the hose, it is necessary to tape it first to keep the netting in place. I used a hack saw to cut it.

I took apart the spare set of oil hoses, I dont think I would try it if I had just one pair.
After polishing the nipple and applying little bit of RemOil I pressed them into the hose.
I used stainless steel ferrules.

[70CB750]

Now the crimping was a challenge, finally I came up with a simple jig.
Square tubing 2x2" and four 3/8" bolts.

I centered the ferrule and tighten those bolt 1/2 turn at a time. After finishing one row of dimples, I moved the ferrule up, turned it 45 degrees and repeated the crimping process.

There are three rows of dimples as you can see.

I am pretty confident it will hold, from what I understand, the oil tank hoses do not carry too much pressure - but I will know for sure soon. I will install them the next oil change - some time this week.
The last crimps were the best - this is the first one -  still have one left since one of the hoses has to be oriented just right - I will crimp it when I have the original out if the bike.

Will let you know if it leaks

I think you tried hard but it looks ugly and not dependable. Sorry.

You could try again but next time tale it to a hydraulic shop and they have the right tools to crimp the fitting.

Greetings from your no-longer Catlett neighbor!

While I think your idea is pretty clever, I have to agree with Lucky, though I hope a bit more gracefully...

The problem I see with it is that you're not crimping the ferrule all the way around so you are leaving avenues of escape around the crimp points. 

I've had success with similar jobs by taking a piece of material, something the width of your ferrule but at least a 1/2 inch, drilling a hole the diameter of the ferrule, then cutting it in half with a band saw (hack saw should work fine) then putting the two halves around the ferrule/hose/fitting combo and squeezing in a vise.  This makes a nice uniform crimp.  You don't want to squeeze so hard the you deform the fitting inside the tube, but enough that you deform the ferrule into the tubing material.

Or do as Lucky suggests and take it to a hydraulic shop, but it's always rewarding to do things for yourself eh?

Good luck!

 They look fine. They're oil lines. Ever said nice bike shame about the oil lines lol. Bad news is that think they might leak. The crimp looks a little more like a pintch. Anywhere that can make A/C lines or hydraulic lines should be able to do a nice tight crimp for you. You could always just throw em and try. Other wise you'll never really know.

[lucky]

Yes I like that idea about making you own tool. Maybe something that you can put in a vice or hydraulic press.

If it leaks I am in it 30 bucks with hose left over, not a biggy in my checkbook. How much pressure they carry anyway?  I never found out.

The oil lines to and from your tank should carry little to no pressure, you have a suction hose to your oil pump and a return hose from the scavenge pump, which shouldn't have any more than a couple of psi at the most.

[jamesb]

why couldn't you just used hose clamps you could have gotten some decent looking ones thats all i got hooked up to my chopper it has the stainless braided sleeves on them i haven't had any issues with it leaking

I figured, snce both hoses have one end open to the atmosfere.

Hose clamps? I don't like their look.  Haha, thats why I made ugly crimps . Those crimps actually look decent. The picture does not do it justice.

Where did you buy the hose?

[70CB750]

Check Colliflower.com. They have a shop near by and looks like theyare in GA too.

I took there one of the fittings and he matched a hose to the nipple.

sorry, no good idea.
a friend of mine crashed cause of a loose hose clamps at these oil lines.
cheaper to use http://pmzracingproducts.com/cgi-bin/image/templates/hosefittings.JPG

Nevermind.

Installed hoses yesterday, took it for a test ride, rode to work this morning - no leaks.
It works!

I love that you try to come up with low cost solutions to things like your air filters, foot pegs and now these hoses mate, well done. I'm wondering if you could make your own swaging tool by modifying a tube cutter? If you were to either "blunt" the cutting wheels or make a couple of new ones with squared off edges, you could maybe shrink the sleeves in nice concentric circles? Cheers, Terry.

[70CB750]

Thank you, Terry

I was considering wire clamp tool, but the SS webbing has to be contained and the wire would not do that, only ferrule like this one.   This jig was the quick and dirty solution, if I had the time and patience I would use the same approach, only massive steel ring instead of the square tubing (it got deformed in the process) and "contact" blocks instead of just bolt ends to crimp the ferrule.
 
Or I can assemble it and take it back to the shop for the final crimping, probably the easiest way:)
 
I have 1500 miles to figure it out - till the next oil change.  If my vanity wins, I will make another set of hoses, this time with better looking crimps and replace these one more time.

The tube cutter is quite an original idea, I like it.  It would be a challenge to hold the ferrule against it, but with enough play time, anything could be solved

This got me to thinking I have a large set of crimpers for my electric fence handles are about 2 feet long they make two crimps at a time and can be adjusted for pressure and they come with different jaw inserts. I will try to make this work and post some pic. You can see these at tractor supply and places like that. mine are like this but larger and open large enough for the hose. Maybe to much money but I all ready have them for my fence.

Where did you get the ferrules?

This is purty neat, I want to give it a shot.

I have a line leaking.

I actually have access to a crimping machine at work.

[70CB750]

Ferrules are from McMaster Carr, but there must be other sources. Stainless steel.

That crimping tool - I dont think it would work. It has to squeze from more than two sides. Commercially six or eight, the four is the lowest number  - I made three rowes of dimples to be on the safe side.

What about something like this thing?

We have one of those at work and I have used it for doing small hydraulic hoses... Shh, don't tell the boss, he told me not to do it 5 minutes before I did.
