I just started work on a 1978 Vespa Grande. The owner's manual suggests I "grease roller housing" every 5,000 miles. Seeing as this might not have ever been done on the bike (and because I am waiting on some parts) I figured I might as well. From what I can tell, roller housing refers to the inside of the variator, so I removed mine and opened it up.
The crackly stuff along the wall is old grease (looks crunchy but still soft).
What is the best way to remove the old grease and clean the rollers, housing, and the rest of the variator?
What grease should I replace it with? Grease grease? Graphite?
The manual asks for Esso Beacon 3 grease. So I was thinking of getting any #3 grease and filling the walls to the same amount of grease as shown above. I saw a thread on here that suggests graphite instead. What do you guys think?
Here's another pic.
