TRANSMISSION SYSTEM
(1) Before starting
the
reassembly work, be
sure
that
all transmission parts are perfectly
clean, check
to
be sure
that
there
is
no
missing parts, and,
when
building
up
sub-
assemblies, refer
to
the
specifications and
assembly standards
to
make
sure
that
each
sub-assembly
is
properly
built
up
with
respect
to
gaps, running clearances, plays,
backlashes, etc.
(2)
Oil
or
grease sliding surfaces,
as
necessary,
at
the
time
of
installing moving parts.
Similarly, grease
"0"
rings, oil seals and
the
like
just
before fitting
them.
(3)
It
is
advisable
but
not
mandatory
that
"0"
rings, gaskets, packings, oil seals,
tab
washers and
the
like be regarded
as
ex-
pendable items and be replaced by new
ones
upon
their
removal in disassembly.
(4)
Wrap through-bolts
with
sealing tape
just
before using
them
in reassembly.
(5)
Have sealant on
hand
and use
it
on the
mating faces
of
cases and covers.
(6)
Build up the transmission in
the
following
sequence:

Reassembling
the
differential gear assembly
(1)
Oil
thrust
liners, fit
the
liners
to
the differ-
en tial gear case, install side gears, position
pinion gears in place,
together
with
liners,
and insert
center
pin.
(2)
Adjust
the
thickness
of
thrust
liners,
as
necessary,
to
secure a backlash
of
0.25
to
0.35
mm
(0.010
to
0.014
in.)
between
pinion gear and side gear.
Backlash
0.25
~
0.35 mm
(0.010
~
0.014
in.)
Shim
stock
for this backlash
adjustment
is
available in
the
following thicknesses:

After
producing
the
specified backlash
,
drive

pin
into
center
pin
to
lock the

latter
pin. Insert differential
shaft
and
rotate
the differential by
hand
to
be sure
that
it
rolls smoothly.
