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

1. Measure depth “A” from the ST upper face to the washer catch surface.

2. Install the forward clutch assembly to intermediate case.

3. Setting the ST, measure height “B” from the ST upper side to the intermediate case mating surface.

4. Obtain the thickness of washer using the following formula.

Calculation formula:

T (mm) = (A − 15) − (B − 15) − (0.75 — 0.95)

[T (in) = (A − 0.591) − (B − 0.591) − (0.030 — 0.037)]

T: Washer thickness

A: Depth from the ST upper face to the washer catch surface

B: Height from the upper surface of the ST to the mating surface of the intermediate case

15 mm (0.591 in): Thickness of ST

0.75 — 0.95 mm (0.030 — 0.037 in): Clearance

5. Select the washer to meet the value “T” obtained from step 4).
