Re: Yaesu G5500 rotor repair progress



I strongly recomend not to use lithium grease, because this mixes
with water and looses its greasing ablity. I recomend a grease
with molibdenium dissulfite, comecialy known as Molicote or
similar brand name. It has excelent lubricating quality's and is 
long lasting and even in lot temperature conditions it still works.
It seems to me that the dark, black colored grease originally
used in the rotors are of  the above tipe.
Bevare of clogging the botom drain hole of the rotor.
