Whether sound when device operates is normal, if any abnormal sound, should reprocess tested speed changer；Checking speed changer simultaneously, whether there is or not oil leaks to show
As operating test by the load to tested speed changer, effectively getting hold of automobile variable speed if any tested speed changer should be reprocessed
The outgoing of device is closed.
