b. Position the rectifier end shield bearing on the base
of tool C-4201. Place the alternator end shield on top of
the bearing so that it is properly alined. With the top part
of tool C-4201 placed on the end shield, press it into place
until it bottoms against the alternator (figure 14-14). New
bearings are prelubricated; additional lubrication is not
required.
