- Measure height "A" from the ST upper face to the bearing end face using the ST.
ST 398643600 GAUGE
- Measure depth "B" from the converter case cover upper face to the bearing catch surface.
- Using the ST, measure height "C" from the ST upper face to the converter case cover mating surface.
ST 398643600 GAUGE
- Using the following formula, calculate clearance "T" to select shims.
Calculation formula:
T mm = (A - 15) - ((C - 15) - B)
[T in = (A - 0.591) - ((C - 0.591) - B)]
T: Clearance
A: Depth from the ST upper face to the bearing end surface
B: Depth from the converter case cover upper face to the bearing catch surface
C: Height from the ST upper face to the converter case cover mating surface
