TM 10-3930-671-24 FIGURE NO.  41. The   Wye   circuit   used   in   22   ampere   TA   alternators, provides a common winding termination, plus three leads to connect the stator to the rectifying diodes  (A  -  B  -  C) (Figure No.  42). FIGURE NO.  42. PULLEY REMOVAL  -  The  various  pulleys  applicable  to the TA alternator, are of a slip type fit.  A Woodruff key is incorporated  on  the  rotor  shaft  for  "keying"  of  the  pulley and fan.  To remove the nut and lockwasher, clamp the pulley in a vise, using an old oversized belt to protect the  pulley  from  damage  by  the  vise  jaws  (Figure  No. 43).After pulley mounting nut, and split lock-washer have been   removed,   the   alternator   should   "pull"   back   and away from pulley. NOTE Should   pulley   be   "frozen"   to   rotor shaft,    while    supporting    alternator, strike   end   of   shaft   with   a   wooden mallet,   plastic   hammer   or   a   special puller to break pulley free from shaft. FIGURE NO.  43. ROTOR REMOVAL FROM FRONT HOUSING - 1. Remove    three    8-32    Phillips    head,    machine screws  and  lockwashers  from  the  front  housing (Figure No.  44). FIGURE NO.  44.
