Subaru Outback: Front Reduction Driven Gear

A: REMOVAL

NOTE: For removal of front reduction driven gear, refer to the "Front Reduction Drive Gear". <Ref. to CVT-297, REMOVAL, Front Reduction Drive Gear.>

B: INSTALLATION

NOTE: For installation of front reduction driven gear, refer to the "Front Reduction Drive Gear". <Ref. to CVT-298, INSTALLATION, Front Reduction Drive Gear.>

C: DISASSEMBLY

1) Using the ST, remove the ball bearing, front reduction driven gear and front reduction driven shaft.

D: ASSEMBLY

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

NOTE: Make sure of the direction of dish plate.

2) 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.

3) Scale and record the weight "Z" of a flat board which will be put on retaining plate.

NOTE:

4) Put the flat board on retaining plate.

5) Using the following formula, calculate load "N", a force of pressing with push/pull gauge.

N = 130 N (13.3 kgf, 29.2 lb) - Z
130 N (13.3 kgf, 29.2 lb) : Load applied to clutch plate
Z: Flat board weight

6) Press the center of retaining plate by applying a force of "N" using push/pull gauge, and then measure and record the compression amount "A".

NOTE: Measure at four points with a 90º interval and calculate the average.

  3. Retaining plate
  4. Dish plate

7) Install the dish plate, driven plate, drive plate, retaining plate and snap ring.

NOTE: Make sure of the direction of dish plate.

8) Measure and record the clearance "B" between the retaining plate and snap ring.

NOTE: Before measuring, press down the whole circumference of retaining plate using your finger.

9) Piston stroke calculation Calculate with A and B dimensions recorded before.

If out of standard, replace with a new drive plate and adjust it within standard.

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

Specification: 2.4 - 2.8 mm (0.094 - 0.11 in)

10) Press-fit the ball bearing into front driven shaft.

NOTE: Use a new ball bearing.

11) Install the seal ring to the front driven shaft.

NOTE:

12) Install the front driven shaft to front driven gear.

13) Using the ST, install the ball bearing.

NOTE: Use a new ball bearing.

15) Apply compressed air intermittently to check the piston operation.

NOTE: Hold the arrowed area with a finger.

E: INSPECTION

F: ADJUSTMENT

1) Using the ST, measure height "A" from the ST upper face to the mating surface of the case.

ST 398643600 GAUGE

2) Measure depth "B" from the converter case cover upper face to the bearing catch surface.

3) Measure depth "C" from the ST upper face to the bearing end face using the ST.

ST 398643600 GAUGE

4) Using the following formula, calculate clearance "T" to select a shim.

Formula: T mm = (C - 15) - ( (A - 15) - B)
[T in = (C - 0.591) - ( (A - 0.591) - B) ]
T: Clearance
A: Height from the ST upper face to the converter case mating surface
B: Depth from the converter case cover upper face to the bearing catch surface
C: Depth from the ST upper face to the bearing end face
15 mm (0.591 in): Thickness of ST

5) Select one to two shims so that the total thickness meets the value obtained from above.
