bearing (20).
(14) Measure distance A between
top of ring spacer and edge of fan end
bell as shown in figure 5-6.
(15) Install shims as required to
provide axial
distance of 0.078 to
0.092 inch for spring washers between
ring spacer and retainer plate.
(16) Install spring washers (16,
figure 5-5).
(17) Apply
thread-locking

CAUTION
To
prevent
damage, it is
extremely
important
that
each
diode is installed in the same
mounting hole from which it was
removed.
(25) Install diodes (30) in same
mounting hole of rectifier ring (27)
from which each was removed during
disassembly.
Ensure that diode flags
are positioned as shown in figure 5-7.
This will make attaching diode wires
