ASSEMBLING AND SETTING THE
CROWN WHEEL AND PINION
Apart
from the ■tting of
components
as
detailed
in
Sections
H2, H3, and H5
it is
not
permissible
to
■t
any
new
parts
(e.g.
crown
wheel and
pinion, pinion
bearings,
differential bearings,
etc.)
to
the axle assembly without
working
through the
procedure
given in
this
Section.
Furthermore, if
a
new
crown
wheel
or a new
pinion is
needed,
a
mated
pair—crown
wheel and
pinion—must be
fitted.
Fitting
a new
crown
wheel and
pinion
involves four
distinct
operations:
1.
Setting
the
position
of the
pinion.
2
Adjusting
the
pinion
bearing
preload.
3.
Setting
the
crown
wheel
position.
4
Adjusting the backlash between
the
gears.
The
following Service
tools
are
required
to
enable these
operations
to
be carried
out
correctly:
Bevel
pinion
and differential
setting
gauge.
Bevel
pinion inner
race remover
and
replacer.
Bevel
pinion
outer
race remover
and
replacer.
