NOTE:

8. Measure height “B” from the ST end surface to the thrust needle bearing using the ST.

NOTE:

9. Remove the snap ring.

10. Place flat boards on the surface plate, and place the snap ring and then planetary carrier assembly overlapping neatly.

NOTE:

11. Install the thrust needle bearing.

15. Using the ST, measure the height “D” from the ST end surface to the washer catch surface of the forward clutch hub.

NOTE:

16. Obtain the thickness of washer using the values measured from step 7) to step 15).

Calculation formula:

T mm = (B − A) − (C − D) − (0.0 — 0.20)

[T in = (B − A) − (C − D) − (0.0 — 0.008)]

T: Washer thickness

A: Height from the ST end surface to the snap ring of the forward clutch drum

B: Height from the ST end surface to the thrust needle bearing

C: Height from the ST end surface to the flat board with the snap ring placed on

D: Height from the ST end surface to the washer catch surface of the forward clutch hub

0.0 — 0.20 mm (0.0 — 0.008 in): Clearance

17. Select the washer to meet the value “T” obtained from step 16).
