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....

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.
