Trying to replace the feed and return oil hose on a Norton. Parts list Section J lists oil feed and return hose as 000950.
I thought this would be an easy purchase locally at an automotive store, but not in my area. The 1/2" oil hose available appears too heavy, simply too large OD, for this Norton application. What are my options? Thanks
This 000950 Norton hose is listed as - Oil pipe, original type neoprene, ½" bore.

Real herringbone oil lines are available by the foot from your nice Britbike parts supplier. :|
 
I just got some Transmission oil cooler hose (3/8" not 1/2") from NAPA. Was $2 / ft and it had the faux-herringbone look. :D

I didn't think herringbone hose was used on British bikes after about 1965, maybe earlier, but maybe..............??? Thank you.

Why did you get 3/8 instead of 1/2? .................the 1/2 was too heavy? Thank you
 
I'm at work right now so can't look but I'm pretty sure the fittings are for 3/8" hose. Maybe I'm full of it.
 
I bought some very expensive herringbone hose from the VOC recently. The setup uses slide on Ferrules at the ends. The Ferrule fits nice and snug and one end but is loosey goosey at the other end, maybe 1/16" slack.
In other words useless!
Back to Gates smooth hose.

The 1/2" ferrules should be originally soldered on the oil pipes, and can be removed with a propane torch if desired.
This will allow 3/8" ID oil hose to be used, which is the ID of the pipes anyway.
My Atlas has the same 3/8 ID x 1/2 OD pipe fittings?
Why did the factory design the oil line ID like this? Increased flexibility with a larger hose size?

I measure the ID of the oil pipes 06-0638 and tank fitting 06-0592 and tank pipe at 0.308 or a little shy of 5/16, the OD of all is 1/2.
000950 hose is listed as 1/2 neoprene hose. my only concern about the bulk 1/2 hose I have available is the OD, as it seems way too large ......and this thickness ads to its inflexibility. And it seems the pressure rating on this available bulk hose (power steering, oil cooler, fuel-vapor) is way too high.....probably adding to the hoses heavy construction. I think all this available hose is 250-300 psi max working with 1000 psi burst.
I seem to be looking for a thin wall 1/2 oil hose, which I thought would be well understood and researched thru this group.....yes? This oil hose affects or is prominent on thousands of pre 1970 vintage British bikes - yes?
 
Here is a bad example how the larger size oil line looks on an Atlas with similar oil tank to crankcase fittings.

The early Commando parts layout shows the crimped hose end pieces that would trim the look a bit nicer, similar to what the original fuel lines used.

Remember that the supply oil line is basically gravity feed low pressure, and the return side has the open end in the oil tank, low pressure.

I hope you can find some suitable hose and maybe some close photos of the early Commando original set up.

Here's a pic of an early model, 69/70 with no oil filter and 1/2 or 5/16 line, not sure which, but they had crimped brass ferrules at each end of the rubber hose with those barbs on the metal pipes, the hose was smooth. I removed the barbs and used 3/8" line on mine, added the filter, and also used hose clamps on the ends. But I also have a ball valve in the feed line with a cut off switch.

Sorry I guess mine is a bit different and doesn't use the 000950 hose or the same oil junction block according to the parts books. Everything seems to be 3/8" hose as far as I could tell on mine (but it has been replaced a number of times). I tested a piece of new 3/8" hose on a smooth socket with 1/2" OD and was able to push it on with my hands. You do notice a slight expansion in the hose.
 
you have a 1972 Commando

buy hose that has an INSIDE DIAMETER of 3/8 of an inch

as suggested, you can go to pretty much any auto parts store and get 3/8 transmission hose and it will be fine
 
Maybe you are looking for neoprene rubber tubing rather than hose. McMaster Carr sells neoprene tubing. They have 1/2 inch ID tubing with two different wall thickness. One is 3/4 inch OD and the other 7/8 inch OD. Here is the link to the page for both:
http://www.mcmaster.com/#catalog/120/134/=tz6t3v

McMaster-Carr also sells hose ferrules. Here is a link for all of them. You will want one with an ID .750 or .875:
http://www.mcmaster.com/#catalog/120/310/=tz6tlg

Unfortunately you will need a crimper for those ferrules - and guess what? McMaster Carr also sells those but they are a bit pricey. You buy the dies separately and they are listed below the crimper:
Crimper: http://www.mcmaster.com/#catalog/120/311/=tz6u8c

If you shop around you might find this stuff at a more reasonable price.

I appreciate the comments so far, but has anyone actually purchased and used 000950 lately? and can relate information to this directly?
 
Howdy,

I purchased a long length of 1/2 herring bone oil pipe from Mick H last year it slides over both oil feed of oil tank and slides on the connector block. It slides on with no force required but is has no side play and is fine for me. I do not have a photo but I can take one if you like. There is no writing or size marked on this particular product but is was relatively expensive in comparison with other pipe I have purchased.

If that ain't the hose for the job then I fear you are on to plumbs.
 
I just can't abide the prices that are charged for the oil lines by the Norton specialists and buy the best size that fits at the auto or hardware store. It's plenty cheap and can be replaced easy enough. If you want to use the crimp on ferrules, you can make a crimper for a 1 or 2 time use out of a drilled out nut cut in half in a vice or even a block of hardwood. Heck, it's not rocket science.

What is this fascination with herringbone? I thought it was a Harris Tweed or something? Of course the early bikes had smooth lines, so what would I know?
 
looks like the photo above shows that someone has sweated on 1/2 " adaptors to those 3/8 pipes so yes 1/2 hose will fit. They are normally 3/8" and 10mm Auto transmission cooler hose will do for that. Buy it by the meter etc. Not expensive either.
As Andychain says, anything with "motorcycle" or "racing" on the label can quadruple the price.

When I bought the hose from Mick he told me it was raving mad expensive and I could probably get hose to fit at a fraction of the price locally. But it fitted all four male oil pipes perfectly and the fact that the workshop dog had stole one of the original pipes made it a no brainer.
As for Harris Tweed , haven't worn it since I went fox hunting in the seventies, but it is good stuff also.

These pipes are factory issue, the reason I know this is I have seen two or three like this off early Commandos with the exposed oil tank and sight glass oil level. The oil return in the tank is also like this.
As for Andy chains comments ,yup he's right there.
 
1969 Commando 20M3S/131880 oil junction block with hose/ferrule remnants.
Also same as Atlas, 650SS, P11 and P11A
The barbed portion is 1/2 OD while the rusty tubing beyond is 3/8 OD.
This would be an app for 000950 and ferrules 023376
