Adjust Backlash and Preload
1. Turn the flange half-bearing adjuster in until the ring
gear contacts the pinion (zero backlash) then back
the adjuster out two (2) notches from the adjuster
lugs.
1 - Flange half
2 - Plain half
2. Tighten the plain half-adjuster until the bearing cup
just starts to turn, this is a zero bearing preload.
3. Tighten the plain half-adjuster two lug notches. Start
with the notch at the top, count two notches coun-
terclockwise on the adjuster, turn the adjuster so
that the notch is facing straight up. You now have a
two-notch preload.
1 - Lugs
2 - One notch
4. Use a rubber mallet to make certain that both bear-
ing adjusters are fully seated.
5. Measure backlash. Make sure it is within specifica-
tion of .008"–.018” (.15-.46 mm).
TIP: To give yourself room to adjust contact pattern, set it
between .012"–.014” (.30-.36 mm).
