1988 Nissan Speedometer problems

[anthony1988]

Ok heres whats the problem is: the speedometer is not working and is not reading at all so today i took it apart to see if the back of the speedometer makes contact with cable and it does but the cable seems to be fine.. inside the middle of the cable where the gauge part hooks in to seems okay so i took that little plastic piece that turns the speedometer out and it was covered in grease.
then put it all back together and still does not work what can be the problem? Please help Me ASAP i need to get it back on the road right away.

Cable is bad or not spinning due to break or gauge is bad, remove gauge and hook a cable or wire to drill and run it and see if gauge moves, if so cable or transmission gear that spins cable. if it does not move gauge it is gear or internal on gauge.
