3) Adjusting drive pinion height
Adjust drive pinion height with shim installed between rear
bearing cone and the back of pinion gear.
(1) Install ST1, ST2 and ST3, as shown in the figure,
and apply the specified preload on the bearings.
to 2).> Adjusting preload for front and rear bearings
NOTE:
At this time, install a pinion height adjusting shim which is
temporarily selected or the same as that used before.

(2) Measure the clearance N between the end of ST3
and the end surface of ST1 by using a thickness gauge.
NOTE:
Make sure there is no clearance between the case and
ST3.

(3) Obtain the thickness of pinion height adjusting shim
to be inserted from the following formula, and replace
the temporarily installed shim with this one.
T=To+N (Hx0.01) 0.20 (mm)
Where:
T = Thickness of pinion height adjusting shim (mm)
To = Thickness of shim temporarily inserted (mm)
N = Reading of thickness gauge (mm)
H = Figure marked on drive pinion head
(Example of calculation)
To = 2.20 + 1.20 = 3.40 mm
N = 0.23 mmH=+1,
T = 3.40 + 0.23 0.01 0.20 = 3.42
Result: Thickness = 3.42 mm

14) Adjusting side bearing retainer shims
(1) The drive gear backlash and side bearing preload
can be determined by the side bearing retainer shim
thickness.
(2) When replacing differential case, differential carrier,
side bearing and side bearing retainer, obtain the right
and left retainer shim thickness from the following for-
mulas.
T
1(Left) = (A + C + G1 D) x 0.01 + 0.76 E (mm)
T
2(Right) = (B+D+G2) x 0.01 + 0.76 F (mm)
T
1&T2: Thickness of left and right side bearing
retainer shim (mm)
A & B : Number marked on differential carrier
C & D : Number marked on differential case
E & F : Difference of width of left and right side
bearing from standard width 20.0 mm,
expressed in a unit of 0.01 mm. For
example, if the bearing measured width
is 19.89 mm, value of E or F is as follows.
20.00 19.89 = 0.11 (E or F)
G
1&G2: Number marked on side bearing retainer
If a number is not marked, regard it as zero.
NOTE:
Use several shims to obtain the calculated thickness.
