2. CROWN GEAR BACKLASH
Using a dial gauge, check the backlash of the
crown gear.
Crown gear backlash:
0.1 — 0.2 mm (0.004 — 0.008 in)
If crown gear backlash is not within the specifica-
tion, adjust the side bearing preload or repair if nec-
essary.
3. CROWN GEAR RUNOUT
Using a dial gauge, check the crown gear runout.
Crown gear runout:
Less than 0.05 mm (0.0020 in)
If the crown gear runout exceeds 0.05 mm (0.0020
in), replace the crown gear.
