the rotor shaft and, while supporting the base of the
rotor shaft, press the bearing and shield into position
on the rotor shaft with arbor press and Tool (2-3858
(Fig. 38).
CAUTION:
Make sure that the bearing is installed
squarely at installation; otherwise, damage to the
bearing will result. Press the bearing on the rotor
shaft until the bearing contacts the shoulder on the
rotor shaft.
(9)
Install the pulley on the rotor shaft. The shaft
of the rotor must be supported in a manner
so that
all pressing force is on the pulley hub and rotor shaft
(Fig. 39).
NOTE:
Press the pulley on the rotor shaft until the
pulley contacts the inner race of the drive end
bearing. Do not exceed
6800
pounds pressure.
(10)
The alternators have the capacitor mounted in-
ternally. Make sure the heat sink insulator is in place
(Fig. 28).
(11) Install the output terminal screw and the ca-
pacitor through the heat sink and end shield.
(12) Install the insulating washers, lockwashers
and lock nuts.
(13) Make
sure the heat sink and insulator are in
position and tighten the lock nut.
(14)
Position the stator on the rectifier end shield.
(15) Position the rotor end shield assembly on the
stator and rectifier end shield. Align the through bolt
holes in the stator, rectifier end shield and drive
end shield.
(16) Compress the stator and both end shields by
hand and install the through bolts, washers and nuts.
(17) Install the insulated brush in the rectifier end.
