Jubilee oil tank connections

Mark,

A. This is the connection for a pipe to the rocker oil feed manifold on the cylinder heads

B. This is the oil retun pipe from the two pipe manifold at the bottom of the engine. Ensure you know which of these two pipes on the manifoldis oil feed and oil return.

C. The filter and engine oil feed union screws in here. I recommend a new composite copper sealing ring. Samesealing ringused on Dominator.

D. Pipe to engine breather near the gearbox output sprocket. I chose this rather than E.The breather and tank pipe stubs are near same diameter. Seemed logical.

E. Breather pipe from oiltank to go through hole in top front of chainguard and give mist lubrication to rear chain. Again, seemed more logical than D, as the small hole in chainguard suggests a smaller bore pipe.

Works fine on my lightweight.

If the rest of the bike matches the fine finish of the tank and seat, look forward to seeing it. Well done.

I'm nearing the end of a complete nut and bolt rebuild of my early 60's jubilee and I could do with some help in working out the correct connections for the oil tank I have attached a picture of the tank that I had zinc plated before having it painted I have lettered the connections in the hope that some one can help many thanks Mark

Hello there,

A little bit of additional info.According to the original OIL PIPE RUNS drawing (TRG Brock & Ray Sage -NOC 1994) you need approxiamately 7 feet of 1/4" bore petrol/oil grade pipe and 22" of 3/16" bore petrol/oil grade pipe. Plus 8 x pipe clips.

You need two lengths - each 20" x 1/4" - from the oil tank to the junction block on the bottom of the engine. Sitting on the bike the Left hand pipe connects to the tee piece on the tank. The 22" x 3/16" pipe goes from the tee piece to the rockers.

The pipe from the breather to the tank is shown as 24" x 1/4" and the pipe to the chaincase is shown as 20" x 1/4".

Good luck and yes it does look good so far.

Patrick.

Hi Mark,

You have certainly put in a bit of work so far -new rims,new tyres and a proper engine rebuild. It's just as well you can make your own stainless items - it all adds up to a lot of time and cost.

Presumably it's your personal choice to do the wheel hubs and frame in black. What colour are you doing the bodywork?

Patrick

Thanks this post anwers a question I was going to ask! I assume its a good idea to fit a remote oil filter? Mark your work looks lovely!

Mark,

You didn't ask about the oil tank drain plug. Just be aware this a BSP thread, 28 threads per inch, not the usual 26 threads per inch.

Bet this has caught a few out. I expect you will have to make one in stainless like me. Couldn't find the correct screw in any stainless supplier lists.

Cheers

Peter
