b) Remove the thrust bearing glands 2 (43-2, 43-4). Lift the tabs of the lock washers
(39-1, 39-2) for the lock nut that hold the inner-ring of the thrust bearings. Loosen and
remove the lock nut with the proper lock nut wrench. Between the lock nut and the
lock washer, there is a think steel sheet. Do not lose it or bend it. Also there is a
washer between the lock washer and the inner-ring.
c) As the gap between the inner-ring of the thrust bearing and the rotor shaft is designed
to be loose, pull out the parts with a thin iron bar, approximately 3mm in the diameter,
with its edge flattened without damaging the retainer.

e) Make sure that the parts from the F rotor and the M rotor are not mixed with each
other. As removing the parts, separate and organize the parts.
