A: Oil Pipework A65 Oil hose

[davidd]

I use regular fuel/oil hose from the auto parts store. I also tend to use banjos on the engine unless I have an old collapsed oil pipe I can cut off.

I buy a brass pipe bushing for the UFM and cut the threads off and run the correct die down it to install it in the oil tank. I install a male barb the correct size for the hose in the bushing. (Can be seen in second photo). Almost all the small parts for the racers have to made up or salvaged. The good parts go to the street bikes.

I believe that is a 1/2" hose on the feed and a 5/16" hose on the scavenge to match the pipes on the head.

I try to match things up, but you can get away with a slight mismatch, but not a large one.

I came across these when I started playing with boats. Non perforated , so better for fuel lines etc. With my aversion to exploding bilges, I have a tendency to over tighten clamps and these don't chew into the hose. https://www.greenlinehose.com/buy/product/g5a-08/52726?ID=/Clamps/Gear/dept-32E

Link does not work for me.

Works for me, so perhaps something to do with you being on the wrong side of the pond? You could try going to greenlinehose.com and enter ABA into the search function.

Imperial bearings have a 3/4" ID whereas the metric ones have a 20 mm ID.

Then it looks like the 54 Comet has metric bearings thanks for the confirmation.

Hi Cyborg, that worked but putting ABA into the search engine only gave me lots of clamp types.

Try this link... it shows the JCS highgrip and Jubilee which are non perforated...or just search for non perforated stainless steel band clamps.

I have bought a variety of stuff from them over the years and have always been very satisfied.

I think the oil lines on my 1948 Rapide are original, since I have had it since 1974, and the lines have ferrules on them. If replaced in USA back before then, and the love this bike was getting, they would have hose clamps, not ferrules. Anyway, they are not Herringbone, although they are rough not smooth, with the appearance that they were wrapped in cloth (like rough bed sheet material) in the mold and the cloth was removed after they were made. I hope that makes sense.

Here is what I use with a pair of blunted pincers I think the UK name is double eared O clips

they come in various sizes once again its worth saying again that we are not dealing with modern oil pressures or even pre unit triumph oil pressures
