d. Turn shell so drive end is up. To properly
position DE stator inside shell (see Figure F–1c):
1) Coil longer ADE stator leads inside ADE stator.
2) Align scribe mark on shell with missing tab
on DE stator. Align 6 insertion studs with
holes in DE stator.
3) Arrange CEN A10–136 stator insertion tool
on DE stator.
e. Press DE stator in place. Insertion studs should
enter holes in DE stator. Make sure DE stator
stops on ledge inside shell. See Figure F–1c.
Remove 6 insertion studs.
Do not use insertion
studs in place of through-
studs in fi nal assembly.
f. On DE stator, remove stator wedges from open-
ings where ADE stator leads and field coil leads
will pass between DE stator windings. See Fig-
ure F–1c for locations of DE stator phase leads
and ADE stator phase leads as arranged in
stator windings.
g. Insert ADE stator phase leads between openings
in DE stator.
Do not damage phase
leads when threading
leads through openings.
h. Insert through-studs from anti-drive end.
See Figure F–1d.
i. Use locknuts to secure through-studs on drive
end of shell. See Figure F–1d. Hex flat on screw-
head must be parallel to winding. Use a suitable
adhesive such as Loctite ® 222 on threads.
Follow manufacturer’s instructions. Torque nuts
on drive end to 4.5 Nm/40 lb. in.
