Im restoring my missuses 91 cooper,

And refreshing some of the suspension/drive components

Ordered a new set of hi/lo's and i just cant seem to separate them from the rubber cone!

Ive soaked in WD40 for a few days now, ive pulled! ive hammered! ive spent at least 4 hours swearing at it!

Still no joy :-(

Is there a trick I don't know?

Or better still is any one near Banstead -Surrey able to help (20 stone body builder if possible)

On another note, i done a compression test on the engine to check its health, and it read a solid 215psi on all four cylinders, seems a little high?

Thanks

Alex

Alex, I ended up hacksawing the trumpets on mine at an angle to remove them. Bloody awkward given the available space.
Hopefully they'll be more easily removed with the high-los as I'm taking them out again to replace the cones (with springs) this weekend, weather permitting.

Good luck!

If you use a wide bolster chisel, wedging it between the rubber cone and the aluminium trumpet, and give it a hard sharp crack with a lump hammer, rotate it 90deg, and just continue doing the same, eventually it will move. Some can be very stubborn, but we never failed to split them this way. HTH Howard

if you have the them out on the bench then use the compresstion tool
get a block of wood drill a hole in it so that the wood spans the end of the cone wind the tool down to compress the cone this will open it up where it sits on the trumpet then just work the trumpet back and forth and up and down this has all ways worked for me

you may find that whilst its all in bits its worth replacing the cones for new GENUINE ones. if the original cones are fitted thay are probably worn out - measure the overall height of them and you will be able to get an idea of how bad they are.

once you have got them off the alloy part inspect the outer metal ring and the inner metal cone - if wither have broken away from the cone then they are scrap as well

They were fronts,

But good news I got it off!

We all went to the other side to wrestle it off, and it fell out under its own weight! it must of got scared and gave in before we got there

Thanks for your help guys

No problem, .... the way I explained is generally for the rears, and the "trumpet/cone" has to be out of the subframe and lying on the floor. That may help you when you want to do the rears!! biglaugh
