1963 650 SS Oil Return Pipes

Forums

Hello 

Does anyone have any tips or tricks for installing the two oil return pipes (to and from the oil tank and engine) on a 1963 650ss and making them properly oil tight?

I have a persistent oil leak from the base of the return pipe and find it really difficult to get this sealed. I seem to be struggling to get the jubilee clip to engage with enough strength to seal. From memory this is 5/16th bore and I've ordered some new pipe in the hope that this will have some more 'give' when applying the jubilee clip. I've also ordered new clips.

I may be over thinking this a bit but it never hurts to ask does it?

I understand that 'proper' hose clips - the type including a flat spring steel band right round the pipe and overlapping at the ends - is preferred to Jubilee Clips, because Jubilee Clips in smaller sizes tend to ruck up the pipe below the closure point.

But nothing I own is oil tight anyway.

Hello Gents - Norton's used crimped fittings on those oil pipes.  If you're going down that route make sure you buy the correct ferrules to fit your piping.  Allow enough slack to permit the pipes to flow through the bend required to fit to the bottom of the cases.  There is a little slack at the oil tank fixings if required.  The oil pipe ferrules are usually zinc-plated brass, unlike the ferrules for fuel pipes which are usually nickel plated and thinner gauge. Good luck, Howard

£2.50 worth of new hose has done the trick. Just ran the bike up for 10 minutes and no leaks! Hooray! Thanks for your input and help.

My 1960 and 61 Dommies came from the factory with no clips at all ,and did not leak , the stretchy pipes gripped the fittings  and with no  significant oil pressure in the pipes  little clamping should be needed. Its only an issue when more rigid pipes are subtituted. Many owners viewed the push on pipes with suspicion and fitted clips anyway !.

Try different hose with a different size bore, the clip is to stop the hose coming off not seal it.
