ARMY TM 9-2815-255-24 AIR FORCE TO 38G1-95-2 MARINE CORPS TM 2815-24/4 WARNING Compressed air used for cleaning can create airborne particles that may enter the eyes.  Pressure will not exceed 30 psig (207 kPa).  Eye protection required. (2) Use compressed air to remove all loose foreign material from cylinders and top deck. (3) Remove cam followers from block.  Wash in dry cleaning solvent (P-D-680).  Lubricate with clean engine lubricating oil (MIL-L-2104) and reinstall in the same bore from which removed. (4) Before cylinder head is reinstalled, clean the threaded holes in cylinder block (for cylinder head capscrews) using 1/2-13 UNC-2A tap about 4.0 inches (102 mm) long.  Use compressed air to remove debris and any fluids which may be present in the capscrew holes.  Replace block if there is evidence of physical damage. (5) Inspect top deck for flatness and serviceability, refer to paragraph 3-47.3. e. Measure cylinder liner height as follows: (1) Bolt  down  liners  using  capscrews  and  flatwashers.    Flatwashers  should  be  at  least  1/8  inch  (3.18  mm) thick.  Tighten capscrews to 50 ft-lbs (68 Nm), refer to FIGURE 3-103. (2) Using gage (JDG451) and dial indicator, measure liner height. FIGURE 3-103.  Measuring Cylinder Liner Height NOTE Variations  in  measurement  readings  can  occur  within  one  cylinder  and/or  between  adjacent cylinders. (3) Measure each liner in four places, approximately at 1, 5, 7, and 11 o'clock positions as viewed from the rear of the engine (flywheel end).  Record all measurements. (4) Liner height above block should be 0.0004 to 0.0040 inch (0.010 to 0.100 mm). (5) Shim  or  replace  any  liner  that  does  not  meet  height  (standout)  specification  at  any  location.    Refer  to paragraph 3-45.2.  for liner replacement instructions. (6) Maximum permissible height difference at nearest point of two adjacent liners is 0.0020 inch (0.060 mm). (7) If liner height is less than minimum specified, one liner shim only may be installed under liner flange.  Two sizes of shims are available 0.002 inch (0.05 mm) and 0.004 inch (0.10 mm). 3-147
