AT Main Case: Adjustment
- Using the ST, measure the height "A" from the AT main case mating surface to the convex surface of oil pump cover.
ST 499575400 GAUGE
- Using the ST, measure the depth "B" from the convex surface of oil pump cover to thrust bearing transferring surface.
ST 499575400 GAUGE
- Calculate the measured value from step 1) and 2), and then set the calculated value as "C".
Calculation formula: C = A - B
- Using the ST, measure the depth "D" from the AT main case mating surface to the thrust bearing transferring surface of front sun gear.
ST 499575400 GAUGE
- Set the value as "E" which subtract the thickness of ST (499575400 GAUGE) from the measured value on step 4).
Calculation: E (mm) = D - 15
[E (in) = D - 0.59]
- Calculation formula:
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 (0.0217 in):
T (mm) = E - C - 0.27
[T (in) = E - C - 0.0106]
T: Thrust bearing thickness
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
Specification:
0.25 - 0.55 mm (0.0098 - 0.0217 in)
NOTE: Calculation formula for "T" above is applied when measuring with the ST (499575400 GAUGE). In the calculation without using ST, substitute the thickness of collar used to calculate the value "E" on step 5). - Select the thrust bearing so that the clearance is within the specified range.
