4) Using the ST, measure the depth "D" from AT
main case mating surface to thrust bearing trans-
ferring surface of front sun gear.

5) Set the value as "E" which subtract the thickness
of ST GAUGE from measured value on step 4).
Calculation formula: E (mm) = D " 15
[E (in) = D " 0.59]
6) Calculation formula:
Select a thrust bearing from the table to adjust
clearance within 0.25 — 0.55 mm (0.0098 — 0.022
in).
When clearances are 0.25 mm (0.0098 in):
T (mm) = E " C + 0.03
[T (in) = E " C + 0.0012]
When clearances are 0.55 mm (0.022 in):
T (mm) = E " C " 0.27
[T (in) = E " C " 0.012]
T: Thrust bearing clearance
C: Distance from oil pump cover mating surface to
rear end of oil pump cover
E: Depth from mating surface of AT main case to
bearing surface of front sun gear
Example:
When the A is 39.50 mm (1.56 in), B is going to be
16.20 mm (0.64 in), so the C would be 23.30 mm
(0.92 in) by calculation.
When the D is 41.90 mm (1.65 in), subtract the
thickness of ST GAUGE from D, and then the value
E would be 26.90 mm (1.06 in).
Calculation when clearance is 0.25 mm (0.0098 in)
T (mm) = 26.90 " 23.30 + 0.03 = 3.63
[T (in) = 1.059 " 0.917 + 0.0012 = 0.143]
Calculation formula when clearances are 0.55 mm
(0.022 in)
T (mm) = 26.90 " 23.30 " 0.27 = 3.33
[T (in) = 1.059 " 0.917 " 0.012 = 0.131]
According to the calculation, the value "T" would be
3.33 — 3.63 mm (0.131 — 0.143 in), therefore se-
lect the thrust bearing with the thickness of 3.4 mm
(0.134 in) or 3.6 mm (0.142 in) thrust bearing from
the table.

NOTE:
Calculation formula for "T" is applied when measur-
ing using ST (499575400 GAUGE). In the calcula-
tion without using ST, insert the thickness of collar
to calculate value "E" on step 5).
