Detail Steps/Work Items
Key Items/References
(1)
Use the special testing rig AEP-0061 to do the
mechanical function inspection.
Refer to Chapter 92.
(2)
Assemble the two-mass flywheel.
(3)
Attach the two-mass flywheel with its primary
mass on the adapter of the testing rig.
Refer to Fig. 85 - 67.
(4)
Attach a hub at the connecting flange of the
secondary mass and the bearing support of the
testing rig.
Refer to Fig. 85 - 68.
(5)
Attach a degree gauge at the input shaft to
measure the freeplay and the clearance angle
between the primary and the secondary mass.
Refer to Fig. 85 - 69.
To measure the clearance angle 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.
 Set the degree measuring gauge to zero.
 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.
 Record the clearance angle value on the degree measuring gauge in the table below.
