■ CAUTION ■
Name the measurement value (B) as “B′” and write it down.

3.Apply thread locking sealant into the thread hole of drive gear.
Use Genuine High Strength Thread Locking Sealant or an equivalent. Refer to Recommended Chemical Products and Sealants.
■ CAUTION ■
Clean and degrease drive gear back and threaded holes sufficiently.

4.Install the drive gear to differential case.
■ CAUTION ■

- Align the matching marks of differential case and drive gear.
- Drive gear is required to be replaced as a transmission assembly. Never replace drive gear alone.

5.Tighten the drive gear mounting bolts with the following procedure.
■ CAUTION ■
Apply anti-corrosin oil to the thread and seat of mounting bolts.

(1)Tighten the bolts in a crisscross fashion to the specified torque.

(2)Tighten the bolts additionally at the specified angle.

Drive gear mounting bolts tightening angle | : 31 to 36 degree

■ CAUTION ■
Check the tightening angle by using the angle wrench [SST: KV10112100 (BT‐8653‐A)]. Never make judgment by visual inspection.

6.Measure dimension (A) to prepare. This is required for selecting side bearing adjusting shim. Refer to Adjustment (GT-R certified NISSAN dealer).
■ CAUTION ■
Name the measurement value (A) as “A′” and write it down.

7.Select side bearing adjusting shim. Refer to Adjustment (GT-R certified NISSAN dealer).

8.Install the selected side bearing adjusting shim (side cover side) to side cover.

9.Press side bearing outer race into side cover with the drift (A) and (B).

A | : Drift [SST: ST01500001 ( — )]
B | : Drift [SST: KV40105310 ( — )]

■ CAUTION ■
Never reuse side bearing.

10.Install the selected side bearing adjusting shim to gear carrier.

11.Press side bearing outer race into gear carrier with the drift (A) and (B).

A | : Drift [SST: ST01500001 ( — )]
B | : Drift [SST: KV40104710 ( — )]

■ CAUTION ■
Never reuse side bearing.

12.Install differential assembly to gear carrier.

13.Install O‐ring to side cover.
■ CAUTION ■

- Apply multi‐purpose grease onto O‐ring.
- Never reuse O‐ring.

14.Install side cover to gear carrier
■ CAUTION ■

- Apply anti‐corrosin oil to the thread and seat of mounting bolts.
- Side cover is required to be replaced as a transmission assembly. Never replace the side cover alone.

15.Install side oil seal (gear carrier side) with the drift (A) [SST: KV40104830 ( — )] within the dimension (L) shown as follows.

L | : 6.3 – 7.3 mm (0.248 – 0.287 in)

■ CAUTION ■

- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi‐purpose grease to side oil seal lip.

16.Install side oil seal (side cover side) with the drift [SST: KV40104830 ( — )] until the side oil seal becomes flush with the side cover end.
■ CAUTION ■

- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi‐purpose grease to side oil seal lip.

17.Check and adjust drive gear to drive pinion backlash. Refer to Adjustment (GT-R certified NISSAN dealer).

18.Check and adjust tooth contact. Refer to Adjustment (GT-R certified NISSAN dealer).
■ CAUTION ■
Adjust the tooth contact within the specified value of backlash to prioritize adjustment of backlash over tooth contact.

19.Install side flange according to the steps.

(1)Attach the protector (A) [SST: KV38105500 (J‐33904)] to side oil seal (2).

(2)Insert side flange (1), and engage the serrated part of the flange with that of the side gear to remove protector.

(3)Put a suitable drift on the center of side flange and drive the drift until sound changes.
NOTE：
Driving sound of the side flange changes to echo‐like sound after complete installation.

(4)Check that the installation measurement (A) of the side flange is as follows.

A | : 370 mm (14.57 in)

20.Fill with gear oil and install filler plug.
