Re: REFLECTOR: Bearing AD
I took a peek at the bearing situation in my RG-E. The forward bearing was
secured very nicely with two AN screws and nuts as described in the AD.
There was good overlap of the flat screw-head surface onto the outer race
of the bearing. Being a conservative type, however, I installed a 7/8-in.
OD flat washer under each screw head, as shown by Dave Black in VV. I even
put a dab of Locktite on the threads.
I also looked at the aft end bearing, and what I saw bothered me. This
bearing was held in with countersink type screws, and the edge of each
screw head barely overlapped the bearing outer race. I can believe that
this arrangement would not hold up if subjected to axial force; the thin
edge on the head of the screw would only need to deform a little bit before
the bearing could be pushed out. Fortunately, the aft bearing is not
retaining axial load, as is the forward bearing. However, I replaced the
countersink-head screws with the recommended AN screws anyway, along with
