Hi, I am changing the spur gear but I don't now how tight the central nut needs to be? any idea? does the parts in the clutch need to have movements or not?
Thanks in advance
 
Tighten it up, then back it off about 1/4 turn. It needs to give to absorb drive train shock on landing, but it should NOT spin on take off.
