Place a large, thick washer and a heavy hexagon nut (l/2-13) on the rod.
Insert the "pull" wires through the tubes (E, Fig. 8) in the exciter armature and
start the generator-to-rectifier leads (A) through.
NOTE: Make certain the wires are not crossed.
Tighten the hex nut against the flat washer to push the armature onto the shaft
and, at the same time, pull the lead wires through the armature (see Fig. 15).
Continue this process until the armature is positioned firmly against the ring
(19, Fig. 7). Remove the threaded rod and installation equipment.
Insert the generator field leads through the holes in the rectifier plate (H,
Fig. 8). The leads should fit smoothly against the exciter shaft between
the windings (J) and the rectifier (H).
Remove the "pull" wires and solder new terminal lugs (B) to the ends of the
generator field leads (A).
C onnect
the leads to the diode mounting plate
terminals as noted in Para. 3, C, (2), (b), above.
Wrap 4 or 5 turns of linen tape (C) around the shaft between the exciter coils
(J) and the rectifier (H) to position and secure the leads. Coat the tape with
insulating varnish .
