TM 1-1520-240-MTF 4-15 b.   Measure distance that either bellcrank end moves. If a bellcrank moves more than 3/8 inch,   there   is   excess   looseness   in   this portion of control system. c.   Isolate cause of excess looseness. (Refer to TM 55-1520-240-23, Ch. 11.) F.   ROTOR PHASING. 1-31. Reference: TM 55-1520-240-23 WARNING Improper phasing can result in injury to per- sonnel  and  serious  damage  to  helicopter. Whenever  the  rotary-wing  system  has  been dephased or components of the drive system (except  the  engine  drive  shafts  or  engine XMSN’s)   have   been   removed   or   discon- nected, the system must be properly phased before the system is operated. The method of checking or obtaining proper phase relation- ship of the rotors is given in the above refer- ence. WARNING Phasing requires alignment of the swiveling actuators  with  the  rotating  swashplates. Do not  perform  any  alignments  using  pivoting actuators. The swiveling actuator on the for- ward rotor is located on the left side of the swashplate and the swiveling actuator on the aft rotor is on the right side of the swashplate.
