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

T2 Required thicknes of right side

(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

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"

of ring gear and drive
pinion
(I) Thoroughly clean ring and drive
pinion gear teeth
(2) Paint ring gear teeth lightly and
evenly with a mixture of powdered
ferric oxide and oil of a suitable con-
sistency to produce a contact pattern
(3) Rotate pinion through several
revolutions in the forward and reverse
direLtion until a definite contact pat-
tern is developed
on ring gear
(4) If contact pattern is incorrect,
readjust thickness
of adjusting washer
Be sure to completely wipe off red
lead upon completion
of adjustment
(5) Incorrect teeth contact pattern
'an be adjusted in the following
manner
Contact pattern

To correct, increase thickness of

to bring drive pinion close to ring gear
