Lubrication help
I just purchased maintenance manuals for my 77 shark. Chip advised that I get the 280F manual as well so I did. I'm a little confused on the lubrication requirements. My log book shows that Mobil 28 grease was used in the main rotor components, but the 280F manual says not to use Mobil 28 grease. As a pilot for periodic lubrication needs what grease should I have in my arsenal? Is the required grease compatible with Mobil 28?
