I have been trying to source the union "bolt" that secures the rocker oil feed pipe to the oil tank. Having failed to find it in the 56 parts list, and yet again among the club spares, I spread my net wider, only to be advised that the "bolt" in question is an integral part of the banjo pipe so I must buy the banjo pipe in order to get the connector. I love my Dommie to bits but having to pay £55 to get a single bolt is pushing it a bit. Anybody out there know where I can get the "bolt", and its 2 washers, for a sensible sum?

Seems very strange to me that the 2 "bolts" at the rocker box connection are readily available. What is special about the bottom one?

Many thanks for your input Anna. I fully understand the fact that there is no bolt but by your definition there is also no bolt securing the banjo's at the rocker box connection. How is it that I can buy the "bolts" and washers for the rocker box connection but I cannot buy the "bolt" and washers for the oil tank connection, Surely they are the same component but different dimensions?

well there is no bolt required and to banjo fits up to the oil tank and the fitting for the return side is screwed up with the banjo and two copper washer and the rocker are feed from the return pipe to the oil tank that why you cannot find the part that dose not exist in any part book

Hi Barry. The content of your response seems to have disappeared but the link that you provided was most helpful. I now know that I am not looking for a "bolt" but a union connector. It also appears that once you know what a component is called , it becomes much easier to source. Oh for a comprehensive illustrated parts list.

Thanks. Ron.

PS I have also been looking for an oil tank outlet pipe and via your link I find that I should have been searching for an "oil outlet filter". Beats me!

If you want to save a lot of money and have access to a lathe these simple threaded spigots are among the easiest things to make from alloy (or bronze preferably). You just have to find your choice of copper, alloy or fibre sealing washers. In the late 60s when comprehensive schools were everywhere they used to teach threading on the lathe and that is where I learned. Attaching the mesh filter is a challenge and it can just be Araldited on. And you don't need a banjo, you can just make a tee in the oil return with a soldered-in feed for the rockers. This lets you choose the size of the oil orifice to keep pressure. I actually put a small filter in the return above the tee and that keeps pressure to the rockers.

All this should take an afternoon and save you just over 100 Euros. When you finally have the cash you can order the right parts (if you can find them). I prefer my own home made bits but, to each his own.

Finally, even if you have only one motorcycle to restore, a lathe is a worthwhile investment that will serve you for a lifetime. (search terms: oil tank, spigot, lathe, rocker feed, low pressure, feed, return.)

Hi Johnathon your interest and sentiment is much appreciated. When I first owned my Dominator, in 1959, I was a technical apprentice with access to turning, milling, grinding,hardening, and plating facilities. Given time, money and permission I could have built my own bike. When I bought the bike back again, earlier this year, I was so chuffed to find that many of the bits and pieces that I had installed all those years ago were still in situ. Much though I would love to have those facilities again now, I feel that it is probably not a good idea to think about major investments for what is probably the last restoration job that I will undertake.

Hi Ron - I don't know if these are any help - first a shot of the oil tank from my 56 model 99 - a future project obviously . If needed I can disassemble the components and take photos - LMK -

Thanks Richard. If only I had had those pics a couple of weeks ago it would have saved me hours of research.

Hi Barry. One non expert to another. Can you help me with this one: Imanaged to get get all the oil tank bits and pieces and prepared to mount the unit in the frame. There I am with the tank in one hand and the top mounting bolts in the other, only to realise that there is no top mounting lug welded onto the frame. Is tere a clip or something that I don't know about? Thanks Ron

Hello Ron, does it bolt to the tool tray

Duh! Funny how you think that you are facing a major problem, when in fact it's you thats the problem. Must be dementure kicking in. Thanks again, I'll unplug the welder and go find the tool tray. Regards Ron.
