NOTE: On Flex 21 machines, it is possible to separate
the gearbox cover from the base while the gearbox is still
installed on the traction unit. The traction band, plane-
tary assembly and reel drive clutch shaft assembly can
be removed from the gearbox in this manner. Service to
the differential, bushings and bearings requires removal
of the gearbox from the traction unit.
