Wanted: Petrol tank spacers and rubbers

[MartinK]

Hi All. I am after petrol tank spacers and rubbers for a plunger 1953 Gold Flash. No one appears to stock these items. 67-8109 front tank mounting tube. 67-8111 spacer collars. 67-8108 tank rear rubbers. Any help, thanks.

I'm not sure what shape the rubbers are on the plunger but I found making my own "U" shaped rubbers for my swing arm very easy, I just used pieces of old inner tube cut into oblongs and formed around a pipe roughly the same size as the frame tube and glued layers on until the tank was a good fit over them. From memory 6 or maybe 8 layers/laminates. To keep them in place on the frame I used a long cable tie wrapped around right around them and the frame.

The rubbers are round solid items with hole in the middle for the bolt. The rubbers fit into the tank lugs. Thanks.

 Kiwi thanks, but Without looking at the parts list, I'm sure they are way different....for the frame inserts, I think I used oil hose or similar over the original collared tubes, but as I have a A7 L/S tank, it just bolts to the frame so can't help with the rear ones, except to suggest doing the same....at least until you find the Rocking-Horse ones

 Ok I relented and looked at the parts list so I can gain some credibility, and came up with same as you part numbers;

 Front Mount;   67-8108 (Rubber 2-2) /   67-8109 (Tube-2) 'A' Group                 
 Rear Mount ;    67-8111 'Petrol Tank rear support stud distance Collar' (2) A10   

 Maybe able to fabricate the front spacers  (67-8109) with washers welded to some tube ?? (at least until you find the Rocking-Horse ones)

If you make your own you need to put a steel collar in the middle to allow the through bolts to tighten.


Metalastic bushes may be possible:

Edit: May need to remove the outer steel from a Metalastic bush to allow the rubber to slide into the holes

Yep, made my own front one. Rubber fuel line just proud of the frame hole, metal tube inside proud to the width of the tank brackets then washers araldited to the metal tube each side. Works good for the last 10 years or so.
Cheers

Hi All. Now sorted. Ended up buying bonnet standoffs made from black anodised aluminium for the spacers and bought a couple of rubber insulators for the tank rubbers.

[Greybeard]

Did you put tubes through the rubbers so the bolt can be properly tightened?

[MartinK]

Hi Greybeard. I have to drill the rubbers as they are a solid cylinder. They are the correct outer diameter and fit the tank brackets perfectly. I have tried drilling but they are too spongy. I thought of putting them in the freezer to make them easier to drill. Time will tell.
Thanks.

 If you can get a pilot hole through them...

 Find a metal rod the right diameter for the hole you want. Heat it up hot with a torch and push it through the rubber. Depending on the rubber, if might flame up, it might let out a small puff of smoke, or it might feel at first the rod wont go through but suddenly it just slides right in.

 Its damn near impossible to "drill" rubber and get a good hole.

Forstner bits drill rubber nicely.
Ordinary steel twist drills do not!

I wonder if rubber hose, such as airline hose might do the job. May need to find or make a suitable metal tube for the centre.


Or as Musky says fuel line.
