TM9-2815-202-34 4-22.   FLYWHEEL   ASSEMBLY e.   Testing (1)  Flywheel  face  runout a. b. c. REPLACEMENT   (Cont) Mount dial indicator (12) on flywheel housing (9) with dial indicator  needle  against  clutch contact  face. Pry  flywheel  toward  engine  block (at six o’clock position) to insure end play is in one direction, Adjust  dial  indicator  to  read  zero at  twelve  o’clock  position. CAUTION When  using  hexagon  head  bolt  at front of crankshaft to turn crankshaft, always  turn  bolt  clockwise.  Serious engine  damage  may  result  if  bolt becomes  loose. d. Rotate crankshaft and record readings at 60 degree intervals (6 readings). Pry flywheel l l toward  engine  block  before  taking  each  reading. NOTE Runout  is  the  maximum  negative  reading  plus  the  maximum  positive  reading.  For example, if maximum readings were 0.004 and -0.007 inch, then runout is 0.011 inch. Maximum  allowable  runout  is  0.001  inch  per  inch  of  radius.  Measure  radius  from center of flywheel to dial indicator needle (clutch contact face). For example if the radius is 12 inches, then the runout should be less than 0.012 inch. e. If flywheel face runout exceeds its maximum limit, remove flywheel and check for dirt or foreign  material  between  crankshaft  and  flywheel.  Remount  flywheel.  If  readings  are  still out of limits, replace flywheel. 4-75
