Most likely a rebuild, IMO. Just a drop of oil in the right place might let
it keep working for a few more years, but you'll have to disassemble the
unit to do it. If you just dump enough oil in the opening to reach the
right place, it will also fly all over and gum up the works.
If you want to try, first download Tony Rhodes' article on the subject, from

A tach is just a speedo without the odometer.
