Introduction of Low ' Motion Transmission Error ' (MTE) Drive Head Assembly

Reason for change :

Product improvement to eliminate humming noise from Differential unit.

Details of change :

As a continuous improvement, contact pattern of crown wheel and pinion has been improved by double lapping during tooling process hence reducing Motion Transmission Error.

Part number change :
