(2)  The  pin  holes  to  be  drilled  for the   new   sleeve   should   be   located   60 degrees clockwise   or   counterclockwise from   the   original   pin   holes.   The   two alternate   pin   locations   are   indicated   by the  broken  line  in  fig.  151. Note.  Be  sure  that  the  pin  holes to  be  drilled  do  not  interfere  with the  oil  holes  located  on  the  knit hole  circle  (fig.  151). (3)   Install   sleeve   139   (fig.   373, fold-out  2),  pressing  it  flush  with  the  hous- ing   outer   surface. (4)   Using   a   0.1855-0.1875   drill, drill  a  hole  0.410  to  0.470-inch  deep  at  one of   the   alternate   locations   chosen.   This hole   should   be   0.250-inch   inward   from   the cover  mounting  surface  and  at  a  30  degree angle   to   the   cover   mounting   surface.   Ref- er  to  figure  151. (5)   Drill   the   remaining   two   dowel pin  holes,  spacing  them  120  degrees  apart. (6)   Install   the   three   pins   (fig. 151),  driving  them  0.005  to  0.015-inch  be- low  the  sleeve  surface. (7)  Line  bore  sleeve  139  (fig.  373, fold-out   2)   to   7.0864-7.0876   inches   diam- eter,  with  a  finish  of  100  RMS  (fig.  151). .  Install   the   power   take-off   cover (fig.   150)   and   gasket.   Secure   the   cover with   ten   3/8-24   x   1-1/4   bolts   and   lock washers.  Torque  the  bolts  to  33-40  pound- feet.
