13 Final Runout Compensation Adjustment

13.1

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.

13.2

Manually rotate the rotor several revolutions and observe the total runout as
indicated on the Dial Indicator.

13.3

Adjust the large and small nuts (C) as described in Section 8 until the TOTAL swing
of the needle is as close to 0.002 in (0.050 mm) as possible.

Refer to the BRC Lathe Operation Manual for instructions on turning rotors.
