What's the best way to clean up the oil lines? Is it even worth it. Mine where all black, then I power washed them now they're a faded white with some black. Can you paint the nylon?

Your best bet is to figure out a replacement, every so often somebody reports a leak from the hose. The oil is under zero pressure in there but old hose will eventually leak.

I used some of that plastic spiral armour sleeve stuff to tidy mine up, the kind used for bundling wiring together. No need to take off the hoses

Black shoe polish!

I pressure washed them too. they came out light gray.
First i tried full strength RID fabric dye to darken them. It worked, but not well enough.
Once dried, I taped off the ends and used VHT flat black header paint.
Still look great after a year

Thanks Flybox, I have some VHT header paint Left over. I'll paint them tonight.

No risk that the rubber in the oil lines start to crack due to age?

I too would be more concerned about the inside. I vote clean up the ends and replace the old rubber. I went with the stainless mesh cover.

My point above, 40 years old rubber is nothing I would call reliable.

Prokop, didn't you DIY braided stainless replacements? If you could please post up details, I'd like to save the leaky pair on my K3.....

Yes, I did. McMasterCarr has SS ferrules, your local hydraulic shop will match your fitting to a hose and all it heeds is a crimp.

Some members, like Kickstart, had luck just taking a hose to hydraulic shop and getting them crimped, I was never able to do that. Napa would not take a chance, Coliflower did not have the right size crimp, it was frustrating.

For my project I found finally this jig at Home Depot, it is used to crimp the new style of house water lines and I paid $25 or so for it and it crimped the hose well enough.

Here it is on Amazon, but I found it locally.

Thanks! I'm having terrible luck at the local hose shops too. Somehow they knew they aren't standard hoses and pulled it outta me that they were for a motorcycle. Once they heard that, there was no talking to them. One more q, what size ferrules to go with? I'm sure I can figure out hose diameters, unless you know them off the top of your head....

oldhatt45 · « **Reply #12 on:** February 16, 2015, 05:53:27 PM »

Ed,

Try this place. http://www.indrubber.com/index.html
It is Industrial Rubber in Elizabeth, NJ.
They have done SCUBA Hoses (5000 psi), Gas Mixing whips (also 5000 psi), and High Pressure lines for the Detroit Diesels I had on my boat.
Admittedly this spans the last 20+ years, but possibly if you call them and ask, you'd only be out the price of a phone call at worst.

Hope this helps

Charlie

Yes, they would not take the responsibility or they did not have the spirit that makes things happen, suckers

I am pretty sure, these were the ferrules: 9256T35

Just put that code in the search on McMasterCarr web and it will come up.

Thank you! I'll give it a shot and post in my K3 build thread. I found a thread that had the correct hose dimensions listed, but now I can't find it again

Will post here when I do.

So why not just buy new stainless ones from CB750 cafe for $69?

edwardmorris · « **Reply #16 on:** February 18, 2015, 02:20:34 PM »

Found the thread http://forums.sohc4.net/index.php?topic=15821.0

The DIY price is half of CB750 cafe price. I'm going to try this.

-10AN 3' stainless hose from Jegs : $20
9256T35 ferrules from McMaster: $5.51

say roughly $30 shipped for everything. Any local auto shop that provides A/C services will have a hose crimper or you can invest in one like Prokop posted above.

First time I see them this cheap. Somebody here posted SS oil hoses he was making for $150 - 2 years ago or so.

How do you remove the old end fitting from the old hoses so the new stainless can be crimped on?

70CB750 · « **Reply #19 on:** February 19, 2015, 03:26:53 AM »

I use hacksaw and cut off the side of the ferrule, parallel to the hose. Or you can do what he did:

Looking at Carpy's oil lines, the ends are not crimped. They are held on by stainless hose clamps with covers.

dgilling · « **Reply #21 on:** February 19, 2015, 09:33:12 AM »

I feel like I have so much more to do that an extra $30 is worth it to just buy from cb750 cafe

ok, so the ferule is not part of the hose end fitting? I make a lot of hydraulic hoses at work and the part that gets crimped/ferule is an integral part of the hose end. They can only be crimped once.

70CB750 · « **Reply #23 on:** February 19, 2015, 03:12:58 PM »

Thats correct, the ferrule slips on the hose for the crimp.

These are not hydraulic hoses, only oil supply. They carry 0 psi pressure.

Stuff's on its way, hopefully some pix soon when I get it together next week. Thanks Prokop and Mikeb4.

edwardmorris · « **Reply #25 on:** March 02, 2015, 07:47:09 PM »

OK, the hose finally arrived today (was sent 3-day priority, took a LOT longer). I think the ferrule size is a bit too small. The -10AN is the correct size for the fittings, they go on almost effortlessly. However once the ferrule is on, its way too tight. I pushed the hardest I could and failed at this point. I'll either need to try with larger ferrules, or have the auto shop guys (bigger and stronger than me) to press them on. The ferrule size is so tight, it may not need crimping

seanbarney41 · « **Reply #26 on:** March 02, 2015, 08:00:38 PM »

Did you try a little lube such as silicon spray or even a little oil?...vaseline?

mrbreeze · « **Reply #27 on:** March 02, 2015, 08:30:58 PM »

I tried years ago out in Wyoming to get Napa to build me some and they wouldn't do it because of the ends being metric. I just saw some cool ends from CycleX for the engine side. They take NPT fittings. Kind of pricey though...$40-50. When I get ready to do it I will get those and get some AN bungs welded onto the tank. Then just buy all the AN fittings & a roll of stainless hose and I'll be good to go for life. It may be pricey but I can always move it all to another bike if I sell mine (not planning to ever sell this one though).

Yep, oil is how I got them in that far, wish I had some hulk powers

Sorry bumping this after a while. I had left this alone after a few set backs, but I did eventually get me a set done. Had to step up on the ferrule size by one and all worked out except for the crimping, its just too odd a size so I gave up and had a hydraulic shop crimp them on. Managed that by being vague and saying they were 0psi oil lines for an old motor

mrbreeze · « **Reply #30 on:** December 27, 2015, 08:04:35 PM »

Never mind! I see you took care of it! Refer to the "what did you get for your bike" thread started by Timbo.
