OK I read SIL 0168. I'm confused a little. It says Aeroshell 14 is preferred, but can't be used with Lamiflex bearings so Aeroshell 22 is OK as an alternative. So is Aeroshell 22 OK to use as a universal grease for all the bearings? I would like to get some feedback from other owners on this. This is my first ownership of a helicopter and I was told that it was wise to give the bearings a shot of grease now and then between annuals. What is the normal practice of some of you hands on pilots?
