Ensure lubricant is applied to the thrust bearings. Be careful when
taking the thrust bearings out of the blade grips. The radial bear-
ings (part #4) should stay within the grips. DO NOT try to remove
these as they have been factory installed. It is best to remove the
grips one side at a time. Before assembly, notice the direction of the
control arm on the grip. It should be assembled as indicated within
this diagram.
