Aurora 88 Piston Problem

[Bucefalo]

Maybee I am the only one to find the piston seel totally fixed in the upper part of the barrel.

There is no chans to get it out, except from the front. I can see the closing disc of the original seel.

Any ideas how to proceed is most welcome.

Heating,/ soaking / pushing on the spindel from above has had no effect

I have the same problem with an Aurora 88K. The only way seems to be a complete disassembly of the pen and removal of the piston from the rear.

Your problem is that the seal is stuck in the barrel, so attempting to turn the spindle does not move it? Is there any slight movement at all, just a little?

 

I had this problem recently, and found a solution which I have not seen specifically mentioned here. Having tried silicone grease or oil without effect, I purchased a seed-oil based body lotion of very slippery qualities, containing no petroleum products or chemicals damaging to humans. I poured a little of this into the barrel over the seal, waited a relatively short while, and found I could now move the piston easily to extract the seal. Because the product washes in water, I was then able to clean any residues quickly and easily (I used a USC) so there was no risk to the pen.

 

The product I found is made in Australia so there is no point in offering you a brand. I am sure something similar would be quite readily available in supermarkets or chemists in your country.
