Hey guys. I replaced the switch alright so far but I am unsure about two things putting it back together.

1) Do I have to press-fit the center piece with the bearings and turn signal switch back on? And if so, how? Like a metal tube and mallet?

2) There are three screws that go thru the turn signal switch, thru the metal bearing assy, then trhu the outer casing, and into a metal ring. Each screw has a small spring on it. Tightening the screws increases spring pressure and draws the ring closer. How tight do I want these?
