gear contacts the pinion (zero backlash) than back
the adjuster out two notches of the adjuster lugs.

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, and turn the adjuster so
the notch is facing straight up. You now have a two
notch preload.

set it between .010"– .012".
