Rear rubber cone

[colonel mustard]

Hi all,
I have a matching pair of rubber cones to go into the rear sub frame of the Innocenti T. One of the cone locating rims is a bit mis-shaped and as sun has, does not locate in the sub frame. I have tried to reshape but having issues for it to still sit correctly. My thinking is the put a three cuts down the locating rim on the cone so it spreads when located - has anyone done this before, is ok to do?
Thanks

There will be a simple way of fixing this Colonel but I don't quite understand the explanation. Maybe a picture or two will help us. I'm going to help my rubber cones pal (I'm a hydro man) later so will look at his cones and sub frame. But they won't be far removed from the hated hydro unit fittings I'm sure!

Hi Peter
Sorry, hopefully the below helps?
Basically the rubber cone is is not totally round where is slots over the locators in the subframe, which means it does not sit correctly.
I have tried to re shape the cone lip but with no luck.
My plan was to cut where I have marked green so the lip adjust around the locator
Hope this makes sense

I would have thought that cutting the rim would not be a good idea as in use it could cause the metal to splay out further and eventually flatten it.

Have you tried putting it all together with the car on its wheels and letting the weight of the car sort out the irregular shape?

Hi
Unfortunately the cone does not sit on the locator enough to get the radius arm in place

I would persist with trying to re-shape it - a nice heavy lump hammer and drift with a radiused end would be my choice of weapons.
If you could shape some wood to cup the side of the ring in it would be better.

Had a look at my friends pick-up this afternoon and can only agree with GraemeC. As for being out of round, being tubular, this usually means being eccentric - or oval! And being oval usually means that the unit has been squashed. I can only suggest that you try to squash it back the opposite way, in a vice. Not the most technical answer but looking at his dry and my hated-hydro, there's a 1/8" or so window of ovality between the male and female - hopefully in your car too......

Has anyone got an old rear rusty subframe that you could hammer it on to??? Section cut out for the job maybe?

Thanks all
I’ve tried pulling it back into shape with a large G clamp, which has worked, to a point. The cone now goes onto the subframe locator but can not fully as the inner section of the cone is rubber lined and does not push, hammer or be manipulated fully over the subframe locator.
Will try and have another go with the clamp to see if that helps.
