How to get the plastic cover off is well described in the Crossfire repair manual.

Here is a description of the procedure and the part number of the right lubricant (Krytox):
Krytox is made by german manufacturer. They do different lubricants and oils.
They are Perfluorpolyether (PTFE) – the brand name by DuPont for that is TeflonŽ.
So it's a kind of Teflon spray, Teflon oil, or Teflon grease.
I've tried Teflon spray and it works perfect for me, but Teflon oil would be better.
