TM   5-2815-241-34&P CYLINDER  BLOCK  -  CONTINUED ACTION LOCATlON ITEM REMARKS CLEANING/INSPECTION   -   CONTINUED NOTE If cylinder sleeves are to be reused, they must be installed in their original location for checking cylinder sleeve protrusion. If one or more cylinder sleeves were discarded, a new  cylinder  sleeve  must  be  substituted.  After  cylinder  sleeve  protrusion  is  adjusted, the shims and spacers used for adjustment must be kept with that cylinder sleeve and shims, spacers, and cylinder sleeves must be tagged for their respective location in cylinder  block  for  assembly. 20. Cylinder  sleeve  (1) a. Using  0-  to  1-inch  micrometer  (2), measure and record cylinder sleeve flange  (3)  width. Do  not  Include  bead  (4)  when  taking measurements. b. Using dial indicator depth gage (5), measure   and   record   counterbore   (6) ledge   depth. c. Subtract  counterbore  ledge  depth  (step b) from cylinder sleeve flange width (step  a). If  the  difference  is  less  than  0.003 inch (0.06 mm), add shims or spacers  so  protrusion,  A,  is  between 0.003  to  0.006  inch  (0.06  to 0.15  mm). If  the  difference  is  greater  than  0.006 inch  (0.15  mm),  tag  counterbore  (6) for  cutting,  steps  53  thru  56,  and record  the  amount  of  material  to  be removed. NOTE The  thinnest  shim  available  is  0.007  inch  (0.18  mm),  therefore  it  may  be  necessary  to use a combination of counterbore cutting and adding shims or spacers to achieve the correct  protrusion  of  0.003  to  0.006  inch  (0.08  to  0.15  mm). If  material  to  be  removed  during  counterbore  cutting  will  result  in  counterbore  depth exceeding  0.412  inch  (10.46  mm),  cylinder  block  cannot  be  reused,  unless  a  salvage sleeve  can  be  installed,  steps  57  thru  63. 2-150
