Infiniti Q45 (FY33). Manual - part 514

SPD884

11. Turn drive pinion in both directions several times, and measure

pinion bearing preload.

Tool number: ST3127S000 (See J25765-A)
Pinion bearing preload:

1.1 - 1.4 N

⋅

m (11 - 14 kg-cm, 9.5 - 12.2 in-lb)

When pinion bearing preload is outside specifications,
replacement is required for pinion bearing adjusting washer
and spacer. Replace with those of different thickness.

SPD919

12. Select side bearing adjusting washer.

Refer to ADJUSTMENT (PD-20).

13. Install differential case assembly with side bearing outer races

into gear carrier.

SPD924

14. Insert left and right side bearing adjusting washers in place

between side bearings and carrier.

SPD559

15. Drive in side bearing spacer with Tool.

Tool number: KV38100600 (J25267)
Spacer location:

Right side

SPD889

16. Align mark on bearing cap with that on gear carrier and install

bearing cap on gear carrier.

17. Install side oil seal.

Tool number: KV38100200 (J26233)

18. Measure ring gear-to-drive pinion backlash with a dial indica-

tor.

Ring gear backlash:

0.10 - 0.15 mm (0.0039 - 0.0059 in)

It backlash is too small, adjustment of shim thickness is
required. Decrease thickness of left shim and increase thick-
ness of right shim by the same amount.
If backlash is too great, reverse the above procedure.

Never change the total amount of shims as it will change the
bearing preload.

SPD884

19. Check total preload with Tool.

Tool number: ST3127S000 (See J25765-A)

When checking preload, turn drive pinion in both directions
several times to seat bearing rollers correctly.

Total preload:

1.4 - 2.8 N

⋅

m (14 - 29 kg-cm, 12 - 25 in-lb)

If preload is too great, remove the same amount of shim to
each side.

If preload is too small, add the same amount of shim to each
side.

Never add or remove a different number of shims for each
side. Difference in number of shims will change ring gear to
drive pinion backlash.
20. Recheck ring gear to drive pinion backlash. Increase or

decrease in thickness of shims will cause change to ring gear
to pinion backlash.

Check whether the backlash varies excessively in different
places. Foreign matter may be caught between the ring gear
and the differential case causing the trouble.

The backlash can vary greatly even when the ring gear runout
is within a specified range. In that case, replace the hypoid
gear set or differential case.

SPD524

21. Check runout of ring gear with a dial indicator.

Runout limit: 0.05 mm (0.0020 in)

22. Check tooth contact.

Refer to ADJUSTMENT (PD-26).

23. Install rear cover and gasket.
