a. Press the ball bearing into the drive end head using a flat block approximately 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 10-24h.)
b. Carefully install the rectifiers in the slip ring end head or rectifier mounting plate by
supporting the unit and using the special tools illustrated in Figure 10-24i.
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 between 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 10-24j.)
d. After the slip ring end head is completely assembled, the stator and rectifier 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.
e. Install the slip ring end bearing and oil seal. Make sure the lip of the oil seal is
toward the bearing. Stake the seal in place. Correct assembly of bearing, seal, inner race and
spacer as shown in Figure 10-24k.
