Subaru Legacy BN/BS (2015-2019) Service Manual: Assembly

1. Apply CVTF to the seal of reverse brake piston and install it to intermediate case.

2. Install the return spring.

3. Set the spring retainer and snap ring.

4. Set the ST1, ST2 and ST3 to intermediate case.

5. Compress the return spring using the ST attached, and install the snap ring.

6. Check the operation of reverse brake piston by blowing compressed air intermittently from intermediate case hole.

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:

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

NOTE:

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:

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

NOTE:

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
