Use a torque wrench to apply the torque values specified in the Table 85-1 at
the angle measuring gauge.
To complete the mechanical inspection do the following steps:
 Turn the two-mass flywheel with a torque of 40 Nm in the counterclockwise (CCW)
direction.
 Release and let it to come to the CCW end stop.
 Turn the two-mass flywheel with a torque of 40 Nm in the clockwise (CW) direction.
 Release and let it to come to the CW end stop.
 Set the degree measuring gauge to zero.
 Turn the two-mass flywheel with the specified torques (Refer to Table 85-1) in the CW
direction.
Do not set the degree measuring gauge to zero during the measurement
procedure.
 Record the clearance angle value on the degree measuring gauge in the table below.
The measured angle values must be within the minimum and maximum
tolerance values.
