Subaru Crosstrek Service Manual: Installation
MANUAL TRANSMISSION AND DIFFERENTIAL(5MT) > Transfer Case and Extension Case Assembly
INSTALLATION
1. Clean the mating surfaces of the transmission case, transfer case and extension case.
2. Apply a coat of grease to the taper roller bearing (transfer case side) of transfer driven gear and the roller rolling surface of the taper roller bearing (extension case side).
Grease:
NICHIMOLY N-130 or equivalent
3. Install the center differential and the transfer driven gear.
4. Install the taper roller bearing (extension case side) outer race to the transfer driven gear.
5. While pressing the taper roller bearing (extension case side) outer race horizontally, rotate the transfer driven gear for ten turns.
6. Measure the height “W” between transfer case and taper roller bearing (transfer case side) on the transfer driven gear.
7. Measure the depth “X” of taper roller bearing insertion part of the extension case.
NOTE:
Measure while the taper roller bearing (extension case side) outer race, dish plate and adjusting washer are removed.
8. Calculate the adjusting washer thickness “t” using the following calculation.
t = X − W − (1.715 — 1.765 mm (0.686 — 0.706 in))
X: Depth of taper roller bearing insertion part of extension case
W: Height between transfer case and taper roller bearing (transfer case side) on transfer driven gear
9. Select the adjusting washer with the nearest value in the following table.

10. Install the selected adjusting washer, dish plate and taper roller bearing (extension case side) outer race.
NOTE:
Make sure the dish plate is installed in the proper direction.
(A) | Taper roller bearing (extension case side) outer race |
(B) | Dish plate |
(C) | Adjusting washer |
(D) | Extension case |
(1) | Paint side |
11. Measure the depth “S” between the transfer case + ST and the center differential.
| ST 398643600 | GAUGE |
12. Measure the height “T” between the extension case + ST and the transfer drive gear.
| ST 398643600 | GAUGE |
13. Calculate the adjusting washer thickness “U” using the following calculation.
U = S + T − 30 mm (1.18 in) − (0.15 — 0.35 mm (0.0059 — 0.0138 in))
S: Depth between the transfer case + ST and the center differential
T: Height between the extension case + ST and the transfer drive gear
30 mm (1.18 in): Thickness of ST (? 2 pieces)
0.15 — 0.35 mm (0.0059 — 0.0138 in): Clearance
14. Select a suitable adjusting washer in the following table.
Clearance:
0.15 — 0.35 mm (0.0059 — 0.0138 in)
