On all models, position rectifier end shield bearing on base of tool (C-4330 for 100 amp. or C-4201 all others). Place end shield on top of bearing, aligning it properly. Press on top part of tool, until end shield bottoms against base of press.
Insert drive end bearing in drive end shield and install bearing retainer plate (on 100 amp. install mounting screws). Position bearing and shield on rotor shaft and while supporting base of rotor shaft, press bearing and end shield into position. Use arbor press and C-3858 tool.
