DIFFERENTIAL CARRIER (Type R200)
Note If values sigrufying H and D' are
not given, regard them as zero and
compute After assembly, check to
see that tooth contact
is correct If
not, readjust
For the tooth contact pattern, see

ADJUSTMENT OF SIDE
BEARING WASHERS
1 If the hypoid gear set, carrier,
differential case
or side bearing has
been replaced with new
part, adjust
the side bearing preload with adjusting
washer The required thicknesses of
the left and nght washers can be
obtained from the following formulas
T, =(A-C+D-H)xOOl +E+205
T2 =(B- D t H') x 0 01 t F+ G+ I 95
Where,
Ti Required thickness
of left side
washer (mm)
T2 Required thicknes of right side
washer
(mm)
A& B Figure marked on the gear
carrier
C & D Figure marked on the differ-
ential case
E & F These are differences in width
of left or right side bearing against
the standard width
(21 00 mm)
If bearing width is 20 82 mm, this
21 00 -2082 =O 18 (mm)
This is the difference in thickness
of side spacer against the standard
width (8
10 mm) If spacer width is
8 02 mm, this figure wdl be as
follows
H Figure marked on rmg gear
8
10 - 8 02 = 0 08 (mm)
Figures for A, B, C and D are
dimensional variations m a unit of
l/loO mm against each standard meas-
urement
To measure width of side bearing,
see differential case assembly pro-
cedure
Before calculation, deterrmne "G"
value by measurmg spacer thxkness If
spacer is deformed or scratched, re-
place
