The blade grips are then screwed onto the feathering spindle using the supplied screw and washer.
The washer is flush against the bearings in the blade grips. These screws have to be fitted using
loctite so again caution is required as too much will mean getting the loctite onto the blade grip bearngs.

Addendum : Following the ecperiences of several people (myself included) do not use the supplied R48 compound to secure the screws. The R48 travels onto the bearings and welds them to the feathering spindle making it extremely hard to remove the blade grips for maintenance. Instead use locktite 222 compound which is only a threadlock compound and should it get onto the bearings will not weld the bearing to the shaft.

Next is the mixer arms assembly, this is fairly straight forward stuff.
