Lithium grease is NOT the stuff to use - it reacts with pot metal (a magnesium/zinc alloy, what the cam gear is made out of) and causes it to break-up through cavitation (gets cavities /holes from the pot metal alloying with the lithium). The aviation industry learned this, and shared the study.

The cam gear is BSR-specific, so Lithium might be a good choice for other constructs, but for anything with a pot-metal product, keep it away.

PHONOLUBE - sold at MCM, AES and other fine distributors, and useable on all phono mechanisms. One tube is about 8 or 9 bucks, lasts years. I still have mine I bought in 1983 or 1984...
