Subaru Legacy BN/BS (2015-2019) Service Manual: Assembly
1. Install the O-ring to plug and install the plug to drive pinion retainer. NOTE: • Use new O-rings. • Apply CVTF to the O-rings. Tightening torque: 25 N·m (2.5 kgf-m, 18.4 ft-lb) 2. Using the ST, install the oil seal to drive pinion retainer. NOTE: • Apply CVTF to the oil seal press-fitting surface and lip. • Install the oil seal in the correct direction. Pulley side
Front differential side
3. Measure the dimension “A” of drive pinion shaft.
4. Press-fit the new taper roller bearing front side inner race using the ST.
5. Press-fit the new taper roller bearing rear side inner race and outer race together. CAUTION: Damage may result if too much force is applied to the roller bearing. NOTE: Press in to a position where the bearing rotates smoothly without play.
6. Tighten a new lock nut using the ST. Using the following formula, calculate the torque for a torque wrench. T2 = L2/(L1 + L2) - T1 T1: 130 N·m (13.3 kgf-m, 95.9 ft-lb) L1: ST1 length 0.1 m (3.94 in) L2: Torque wrench length m (in) [Required torque setting] T2: Tightening torque: N·m (kgf-m, ft-lb) Example:
NOTE: Tighten the lock nut while directly aligning ST1 and torque wrench.
7. Apply differential gear oil to roller of bearing and rotate the bearing several times. 8. Measure the starting torque of the bearing. Make sure the starting torque is within the specified range. If the torque is not within specified range, replace the roller bearing. Starting torque: 16.3 — 42.7 N (1.7 — 4.4 kgf, 4.4 — 9.6 lbf)
9. Crimp the lock nut in 2 locations. 10. Measure the dimension “B” of the drive pinion shaft.
11. Obtain thickness “t” mm (in) of the drive pinion shim. t = 6.55±0.1225 − (B − A) 12. Select three or less shims from following table.
13. Install the shims selected for drive pinion retainer and drive pinion shaft assembly. NOTE: Be careful not to bend the shim. Tightening torque: 70 N·m (7.1 kgf-m, 51.6 ft-lb)
