I'm right now having to re-centre the hammers from a 20 year-old 
Schimmel upright a colleague has sent me -- graphited bushings.  I 
tried Protek on one or two of them and this made them stiffer, so I 
am replacing the pins with pins of the same size.  Two or three 
passes with an almost smooth broach and a smear of deer tallow on the 
pins is yielding very consistent results and the job will take little 
over an hour.

Graphite seems to me a very bad and totally unnecessary idea, but I 
was surprised to find it used on a very nice set of grand shanks I 
got from Detoa last year and haven't yet used.
