Rocker Box oil feed pipe
« on: 26.03. 2016 19:27 »
Just received a new rocker box oil feed pipe. Went for the first 90 degree bend, heated the pipe just above the tee from the banjos and it was perfect. Then for the second 90 bend to route the pipe along the o/s of top tube. Heated the pipe again just started bending when the pipe snapped in two. I don't posses a small tube bender but have bent small tubes by hand for years with no problem. I don't fancy spending another £20 pounds for it to do the same. I prefer not to name the supplier but it was not from Bikerbsa, so has anyone had any luck with fitting these straight silver coloured replacement tubes.

Sorry I can't answer your question but the copper pipe (which I've always assumed is correct for the bike but does anyone know the correct spec for sure?) can be bent several times without annealing and does not kink. I've assumed it's standard brake line tubing? I've soft soldered it into the fittings without any problems, but others may prefer a higher temp solder.

You would get a lot of brake tubing for 20 quid.

fitted one last year, the pipe (not copper) bent easily enough, although I did not make really sharp bends

I make them out of copper tubing, silver solder the joints and get the finished article zinc plated.

Wassells have been selling rocker feed pipes with copper tubing between the banjos and brass tubing from the 'T' down to the oil tank. I used one such pipe on my Super Rocket and found it very difficult to work with but I did manage in the end. The one I used on the SR was from a batch I bought from Wassells about 12 months ago. After fitting the SR pipe I contacted Wassells and they said they weren't aware that the pipes had been made from brass; presumably they are made in India or China and maybe the manufacturer strayed from the spec he had been provided with........ no point in speculating really. Wassells said they were happy to take them back so I sent them all back and now I only stock the ones supplied by MCA which are all copper tubing and a delight to work with. When buying rocker feed pipes you need to ask what they are made from, sadly.  Grrrrrrrrr!

 I maybe wrong, but I've a feeling I sourced some (is it 1/8") from either a scrap yard, or a refrigeration supplies (I think they're about all else who use it)

I imagine Bundy tubing as used in brake systems and easily shaped and soldered would be ok.

Thanks for all your feedback, I will get some brake piping and silver solder it into the tee.

I really don't see why soft solder will not do. The pressure in the rocker box feed must be very low. Mine is attached with a proper union to the oil tank return feed but isn't it attached with a short length of rubber tubing on later models? If so the pressure cannot be high. Soft solder works fine on all of my central heating radiator pipework, (Australian readers may need to Google Central Heating  ;D)

I've tried unsuccessfully a couple of times to find a supplier of the brass solder T piece and banjo connectors.  Which is irritating as I'm sure they are available for not much money from someone.

Anyone got a source?

Also, soft solder has worked well enough for me.

What's central heating? I bung a half a gum tree in an old kero tin to keep the nippers toasty warm!
There is SFA pressure in the return line, I use fuel hose and hose clamps on the return line oil filter
