Prop-pitch rotor help needed

I hope this is not repetitive.  I sent this request ealier this morning
but since it han't shown up on the reflect yet I suspect something went
wrong.

I am in the process of putting up a beam for 40M and have recent
acquired a prop-pitch rotor that I would like to use as the antenna
rotator.  I have one small problem - I know nothing about the electrical
requirements of a prop-pitch.  The unit had been previously used as
an antenna rotator so most of the hardware is there, antenna clamp,
tower plate, and AC syncronous tX/rx for the direction indicator.

My main questions at this time are:

1) What voltage does the prop-pitch opperate at? is it AC or DC?

2) What can I do to give it a good check out before putting it up on the
   tower?  Short of tearing the whole thing apart and rebuilding it.

3) How does one wire the AC syncronous tx/rx pair?  Each has screw
   terminals marked - "X", "Y", "1", "2", and "3".  Also each unit
   has on it that they are 115V 60hz type syncros.

4) I noticed that the output shaft of the prop-pitch has essentially no
   backlash.  Should I be woried that the unit is ceased and will need
   some serious overhauling? or is this normal for a prop-pitch?

Any help would be greatly apreciated.

Cheers and hope to see you on 40M soon,
