Preliminary Runout Compensation Adjustment

8.1 Mount a Dial Indicator (A) rigidly on the hub knuckle assembly. The stylus of the Dial

Indicator must be in contact with surface B as shown. Lightly tap the Dial Indicator to
ensure the needle returns to the same spot to verify it is mounted securely.

8.2 Rotate the Centering Plate 360 degrees several times while watching the total swing

of the Dial Indicator needle. Set the mark (C) on the bezel of the Dial Indicator to the
MIDDLE of this total swing as shown.

The goal is now to adjust the large and small nuts (D) on the Cranks so that the
TOTAL swing of the needle is 0.004 in. (0.1 mm) or less.
