It's called "an old main shaft." The problem I encountered when mating an OD
to a transmission is the tendency is to set the transmission on end (bell
housing down) and lower the OD onto the mainshaft. The problem with this is
when
the OD is inverted gravity will cause the moving portion of the OD clutch to
slide forward and the helical cut of the gears will cause the sun gear to turn
and now it no longer aligns with the sprag clutch splines.
then you turn it over to realign it and now the clutch disk is in contact
with the ring gear and it won't turn.
The solution I've used (once the sun gear and sprag clutch splines are
realigned) is to bolt the OD output flange to a big board and with it facing up
(flange down) and lower the transmission onto the OD. The weight of the
transmission will help compress the springs, too.
