If you use any other method except the method that
is given here, always remember that the bearing
clearance must be removed in or der to receive the

3. Turn the flywhee l while the dial indica to r is set at
0.0 mm (0.00 inch) at location (A). Read the dial
indicator at locations (B), (C) and (D).
4. The difference between the lower measurements
and the higher measurements that are performed
at all four points must not be more than 0.38 mm
(0.015 inch), which is th e maximum permissib le
