7. Place the dish plate, driven plate, drive plate and retaining plate neatly in this order on surface table.

8. Set the dial gauge to retaining plate, and read its scale.

NOTE:

The value, which is read in the gauge at this time, is zero point.

9. Scale and record the weight “Z” of a flat board which will be put on retaining plate.

NOTE:

• Use a stiff board which does not bend against load as a flat board to be put on retaining plate.

• Use a flat board weighing less than 84 N (8.6 kgf, 18.9 lb).

10. Put the flat board on retaining plate.

11. Using the following formula, read the push/pull gauge, and calculate “N”.

N = 84 N (8.6 kgf, 18.9 lb) – Z

84 N (8.6 kgf, 18.9 lb) : Load applied to clutch plate

Z: Flat board weight

12. Press the center of retaining plate by applying a force of “N” or more using push/pull gauge, and then measure and record the compression amount “A”.

NOTE:

Measure at four points with a 90° interval and calculate the average.

13. Install the dish plate, drive plate, driven plate, retaining plate and snap ring to intermediate case.

NOTE:

Install the dish plate in the correct direction.

14. Measure and record the clearance “B” between the retaining plate and snap ring.

15. Piston stroke calculation

Calculate with A and B dimensions recorded before. If it exceeds the limit, replace with a new drive plate and adjust within the initial standard value.

S mm (in) = A + B

S: Piston stroke

A: Compression amount of drive plate and dish plate

B: Clearance between retaining plate and snap ring

Initial standard:

2.88 — 3.18 mm (0.113 — 0.125 in)

Limit thickness:

3.38 mm (0.133 in)
