remove or replace spline adapter, or ring
gear separation may occur.

(T6) into spline adapter of starter gearshaft as-
sembly to stop rotation of gearbox gears while
generator spline adapter is being removed and
installed. Secure adapter assembly (1) to studs

Position spline adapter (2) (tapered end first) in
generator output shaft splines.
Assemble jack screw (3), jack nut (4), support
bridge (5), guide (6) and swivel (7), then install
onto studs of generator mounting pad securing
with MS21044N6 or equivalent nuts.
If generator mounting plate has been re-
moved, it may be necessary to push the
spline adapter in approximately 11/4 inch,
back off jack screw (3) and then retighten
the nuts securing the adapter kit to the
Turn jack screw (3) down until guide (6) makes
contact with spline adapter (2) and engages
