block   is   very   important. The  allowable  standout  is 0.002   to   0.005   inch.   Measure   cylinder   sleeve   stand- out  as  follows: (a)   Using   a   depth   micrometer,   measure depth   of   cylinder   sleeve   counterbore   in   the   cylinder block   (measure   at   two   more   locations).   The   depth should be 0. 315 to 0. 3165 inch. (b)   Using   a   micrometer,   measure   width   of cylinder   sleeve   flange   (measure   at   three   or   more locations). The  width  should  be  0.3185  to  0.  320  inch. (c)   Subtract   counterbore   depth   from   width of   cylinder   sleeve   flange. The   result   is   the   cylinder sleeve  standout.  If  the  standout  is  not  within  0.  002  to 0.005   inch,   install   a   cylinder   sleeve   shim   of   the   prop- er   thickness   in   the   sleeve   counterbore   to   bring   the standout   within   the   allowable   limits. Cylinder   sleeve shims   are   available   in   0.005-,   0.   010-,   0.   010-, 0.015-  and  0.  020-inch  thickness. If  shimming  will not   correct   the   cylinder   sleeve   standout,   reworking of   the   counterbore   will   be   necessary. (6)  To  double  check  the  cylinder  sleeve  standout, insert   sleeve   with   shims   into   the   cylinder   block.   To hold   flange   of   sleeve   firmly   against   the   counterbore seat  in  the  cylinder  block,  make  up  a  bar  similar  to the  one  illustrated  in  figure  14-44.  Place  bar  across top  of  sleeve  and  secure  in  position  with   9/16-12   cap- screws   and   flat   washers. Tighten   capscrews   evenly   to 60  foot-pounds  torque. Using   a   depth   micrometer, measure  the  distance  between  the  top  of  the  block  and top  of  the  sleeve  flange  at  three  or  more  locations. Make   certain   the   standout   measurements   are   made from  the  top  of  the  cylinder  block  to  the  top  of  the sleeve  flange  and  not  on  the  firewall. (7)   Remove   sleeve.

(1)  Two  packing  rings  are  used  on  each  cylin- der   sleeve: one  black  on  water  side,  one  red  on  oil side. CAUTION Rubber   packing   rings   are   easily   damaged. Use   extreme   care   in   handling   and   install- ing  them  in  order  not  to  cut  or  shear  them. Rings  swell  and  expand  after  short  contact with   petroleum   products   and   certain   types of   permanent   anti-freeze. This   causes them  to  drop  out  of  their  cylinder  sleeve grooves   and   their   installation   in   the   cylin- der   block   becomes   impossible.   Do   not pre-soak   or   apply   lubricant   to   a   ring. (2)  Thoroughly  clean  the  packing  ring  grooves in   the   cylinder   sleeve. Stand  sleeve  on  a  clean  work bench  with  packing  ring  end  up.  Install  black  on bottom   groove;   install   red   on   top   groove.   The   rings must  be  installed  dry  without  lubrication  of  any  kind. CAUTION New  cylinder  sleeve  packing  rings  must  be used  at  each  installation  of  a  new  or  used sleeve. Make   certain   rings   are   not   twisted. (3)  Brush  a  light  coat  of  vegetable  or  mineral oil   in   lower   sleeve   bore   in   cylinder   block.   Be   ex- tremely  careful  so  packing  rings  are  not  cut  on  sharp edges  of  bore  in  block  when  installing. CAUTION Do  not  use  any  other  lubricant  except  vege- table   or   mineral   oil;   doing   so   prevents proper   installation   and   operation. (4)   Install   cylinder   sleeve   as   follows: (a)   Insert   cylinder   sleeve   installer   tool   in cylinder   block. Brush  bore  of  tool  with  a  light  coat of  vegetable  or  mineral  oil. (b)   Position   cylinder   sleeve   with   packing rings. (c)   Carefully   force   the   cylinder   sleeve   into the  sleeve  lower  bore  of  the  cylinder  block. b.   Crankshaft   Installation.
