How to remove the ferrules on the oil cooler?

I am getting a pile of fasteners from my 1200 ready to go in for plating.  One part I'd like to include are the mounting nuts for attaching the lines to the oil cooler.  I'm having a hell of a time getting the ferrules off the oil cooler - # 16 in image below:


Any tips on how to remove these?  I have soaked the inlet stubs in penetrating oil and tried gentle heat - but they still won't budge.
 
I cut them off and replace with new.
Sometimes it means cutting off the nut as well to make space to get to the olive.
Beware, the aluminium tube cuts way more easily than the brass olive.
New olives and nuts are available from the usual suspects.
 
This subject comes up quite a bit.

I ground my olives down in two spots (180 degrees apart) and then very carefully filed the rest of the olive with swiss files until a tiny crack appeared on the surface (both sides). The olive then just about falls off.

As Grant says the alumimium is much softer than the olive so go careful. There may well be a groove where the old olive was, so you might want to put the new one in a different spot.

The olives, nuts and fittings are available from just about any hydraulic hose supplier in your area (Pirtek, Hydraquip etc). I bought nuts from them and turned them down on a lathe to mimic the originals - cheap as chips!!!!

Paul - did Diana share with you any stories about my skills operating power tools...?  :) 

I'll be trying to minimize collateral damage - but good to know that a spare is nearby.
 
It's not part of the hose, it's part of the oil cooler.
You see bikes with new shiny hoses but rusty top nuts as they are held captive by the olive/ferrule.
