11-32. ASSEMBLY OF ALTERNATOR.
a. Press the ball bearing
into the drive end head using a flat block approxi-
mately two inch square so that the pressure
is exerted
on the outer race of the
bearing.
Install the retainer
plate. With the snap ring and retainer
cup in place
on the rotor shaft, use a tool that fits over the shaft and against the inner bearing
race,
and press until the inner bearing
race is against
the snap ring retainer
cup. (Refer to Figure 11-24.)
b. Carefully install the rectifiers
in the slip ring end head or rectifier
mount-
ing plate by supporting
the unit and using the special tools illustrated
in Figure
11-25.
CAUTION
Use an arbor
press,
do not hammer.
Reconnect the
stator
leads to the rectifiers.
When soldering
these
connections,
use pliers as a heat dam on the lead be-
tween the solder
joint and the rectifier.
Too much
heat will damage the rectifiers.
c. Reassemble the rectifier
mounting plate studs and insulators,
making sure
they are in the correct
order. (Refer to Figure 11-26.)
d. After the slip ring end head is completely
assembled, the stator
and rec-
tifier leads must be secured
to the rectifier
mounting plate with epoxy.
Make
sure the stator
leads are positioned
so that they do not interfere
with the rotor.
