is carried out at a point 90° from the axial direction of the motive power rotain shaft,
and the adjustments are made in the following manner:
i)
When the same drive pinion and ling gear are to be reused, remember wirhour
fail
to use the shims thar were fitted initially.
ii)
When using a new ring gear and pinion:
a)
Use a mandrel instead of the differential carrier and use the shims [(two sizes
available: 0.004, 0.008 in (0. I, 0.2
mm)] between the front axle and front axle
case cap to adjust
the reading for A to 0.6280 - 0.63I9 in (I6 t 0.05mm).
b)
Fit the differeniial assembly with the fronr axle case.
c]
Insert shims [two sizes available: 0.004, 0.012 in (0.1, 0.3 mm)] between
the fronr axle
(L) and between ball bearing 6207 so that the backlash /Item 6) is
0.005
- 0.007 in (0.13 -0.18 mm).

d) At this time, be sure that there is no space between the differential

the ball bearing 6207 (both sides), the front axle (L) and ball bearing
6207
(ligh thud).
e)
Insert shims
[0.004. 0.012 in (0.1, 0.3 mm)] between the fronr axle (R]
and front axle case so that there is no space at the places mentioned in Irem (d).

Irem I2 through I5 refer to measurements for the bevel gears in the front-
gem cases;
the adjustments are made in the following manner:
(I)
When using the same bevel gears, remember wirhour fail to use the shims
thar were fitted initially.
