TM 10-3930-659-34 5-2. CYLINDER LINERS MAINTENANCE (Con’t). 13.Remove  piston  (8)  from  cylinder  liner  (4)  and  insert piston  upside  down  in  cylinder   liner.      Position piston  1  in.    (25.4  mm)  below  top  of  cylinder liner. 14.Using    feeler    gage,    measure    and    note    clearance between     piston     (8)     and     cylinder     liner     (4). Clearance   must   be   0.003-0.006   in.        (0.076- 0.152 mm). 15.Difference  between  measurements  in  steps  12  and 14  is  cylinder  liner  taper.    Cylinder  liner  taper must not exceed 0.002 in.  (0.051 mm). 16.Remove piston (8) from cylinder liner (4). NOTE Perform steps 17 through 19 only if further inspection is required. 17. Remove seven screws (3) and washers (2) from engine block (1). 18. Remove cylinder liners (see subparagraph c). 19. Inspect outer  surface  of  cylinder  liners  (4)  for  pitting  and  corrosion.    Using  nonelectrical  wire  and  rule,  measure depth of pitting or corrosion.  Depth must not exceed one-half the wall thickness of cylinder liner.  If depth exceeds specification, replace cylinder liner (see subparagraph c). 5-16
