ARMY TM 9-2815-256-24 AIR FORCE TO 38G1-96-2 MARINE CORPS TM 2815-24/5 d. Measure cylinder liner height as follows: NOTE If liner height was not checked when liners were removed, refer to paragraph 3-34.6., step e, or a new liner is being installed in a new or used cylinder block, liner height must be checked. (1) Be sure liner bore in cylinder block is clean. (2) Install liners without -rings and packing. CAUTION Liner should rotate smoothly by hand when installed.  If not, remove liner and polish bottom liner pilot bore in cylinder block with emery cloth.  Use a shop towel or other suitable means to collect debris when polishing bore. (3) Install liner with its mark toward the front of the engine.  Secure with capscrews and washers.  Tighten screws to 50 ft-lbs (68 Nm). (4) Using gage (JDG451) and dial indicator, measure each liner height in four places, at approximately 1, 5, 7, and 11 o'clock positions as viewed from the rear of the engine (flywheel end).  Record all measurements. (5) Liner  height  specification  is  0.0004  to  0.004  inch  (0.01  to  0.10  mm).    Maximum  permissible  difference between readings within one cylinder or between adjacent cylinders is 0.002 inch (0.06 mm). (6) If  liner  height  is  above  specification,  check  cylinder  block  for  burrs  on  liner  support  flange  or  incorrect counterbore depth. CAUTION Only  one  shim  (1,  FIGURE  3-161)  is  allowed  per  cylinder.    If  liner  requires  more  than  one  shim, install either a new liner or engine block. (7) If liner height is below specification, install one liner shim on bottom of liner flange.  Two sizes of shims are available: (a) 0.002 inch (0.05 mm) Part No.  CD15466. (b) 0.004 inch (0.10 mm) Part No.  R65833. 3-47. REPAIR. 3-47.1. Cylinder Liners. a. Deglaze cylinder liners as follows: (1) Fabricate cylinder liner holding fixture (FIGURE D-3, Appendix D).
