General Rules on Adjusting Bearings

1. Take extreme care when removing and installing bearing cups and cones. Use only an arbor press for installation, as a hammer may not properly align the bearing cup or cone. Burrs or nicks on the bearing seat will give a false end play reading, while gauging for proper shims. Improperly seated bearing cup and cones are subject to low-mileage failure.
2. Bearing cups and cones should be replaced if they show signs of pitting or heat destress. If destress is seen on either the cup or bearing rollers, both cup and cone must be replaced.

CAUTION: Bearing end play and drag torque specifications must be maintained to avoid premature bearing failures.

Used bearing may lose up to 50 percent of the original drag torque after break-in.

CAUTION: All bearing adjustments must be made with no other component interface or gear intermesh, except the transfer gear bearing.
