Hi,

Welcome.

Lubricating the feathering spindle wont do any harm to the spindle but depending on the lubricant used it might rot the rubber dampers. Unfortunately I dont know what the green liquid is made of so I cant say. Saying that though, with the ammount of centrifugal force involved in a spinning rotorhead, it wont be in there long so it shouldnt cause too many problems.

If the bearings you are refering to are the thrust washers (2 grooved washers with a ball race in between with an "in" and an "out" stamped on the washers) then absolutely you need to switch it around as the blade grips will lock up when the heli is flying. If its the sealed bearings (3 in each blade grip 2 big ones and a small one) it doesnt matter what way round they go in however, the order of the bearings is very important eg small bearing, big bearing, big bearing, thrust washer.

Hope this helps... Azzy
