anti-drive end phase lead is located. Cut the
three terminals off the anti-drive end phase
leads and discard.

8. Position the shell in the support stand with the
faulty stator in a downward position. Place sta-
tor installation/removal tool XA3320 on top of
the tabs of the stator being removed. Ensure
the recessed portion of the tool is fully engaged
with the stator tabs
Ensure the stator installation/removal tool is
engaged with the stator tabs of the part being
removed and not the stator in the upper position.
The shell assembly is manufactured with a raised
area in the center of the shell. The stators can
only be removed by pushing them out through
the end of the shell.
9. Place the shell assembly into a hydraulic press
and remove the faulty stator. Figure 10-86
shows the drive end stator being removed.
FIGURE 10-86.
NOTE: The tabs of the stator may bend slightly
downward during the removal process. Continued
downward pressure will push the stator out of the
shell.
