17. Lightly coat the shaft extension and bearing bore
with oil. Assemble bearings (24), as shown in
FIGURE 7-
5
, page 349, on the shaft. Assemble
the press plates (refer to Figure 7-2,
Disassembly, page 338), on the bearing and
install the jack screws, FIGURE 7-
16
.
Progressively tightening nuts on the jack screws
presses bearings in place. To prevent possible
damage to threads on the shaft, press one
bearing over the shaft into the bore at a time,
rather than with both bearings stacked together.
When the first bearing is flush with the top face
of the bore, the second bearing may be started.
Tighten nuts on the jack screws evenly to prevent
cocking of the bearings on the shaft and in the
bore.
It is not recommended to hammer
bearings of this size in place.
18. Install the bearing clamp plate (10) and four
“nylok” type screws (38), FIGURE 18. Install lock
washer (27) and spanner type nut (26) on the main
rotor shaft (2) and drive up tight. This operation
pulls the rotor shaft through the bearings until the
shims and bearing spacer are clamped solidly
between the rotor end and bearing, assuring a
