e. Place the end bracket onto the stator assembly,
lining up the alignment marks on the top of the
stator and end bracket. See Figure 6-21.
f. Thread the four overbolts with locating
washers through the end bracket and into the
generator adapter. See Figure 6-21 and
Figure 6-22. Position the locating tab of each
washer to the outer edge of the oblong
(OBROUND) hole on the end bracket. The
overbolts should be parallel to the outside of
the alternator. If the overbolts are slanted,
rotate the locating washer 1/2 turn. Do not final
tighten the overbolts at this time.
