ARMY TM 9-2815-254-24 AIR FORCE TO 38G1-94-2 (2)   Use  a  dial  indicator  to  measure  shaft  central  portion  run-out.  Limit  on  run-out  is  0.024  in.  (0.6  mm).  If  run- out exceeds limit, replace shaft. If run-out is very slight, an arbor press may be used to correct shaft. Shaft must  be  cold. b. Use  a  micrometer  and  measure  rocker  arm  shaft  outside  diameter,  refer  to  FIGURE  3-55.  The  standard  diam- eter is 0.747 to 0.748 in. (18.98 to 19.0 mm), with a limit of 0.744 in. (18.90 mm). If measured value is less than limit, replace rocker arm shaft (18, FIGURE 3-52). FIGURE  3-55.  Rocker  Arm  Shaft  Outside  Diameter c. Use either a vernier caliper or a dial indicator and measure rocker arm (12, 14, 16, and 17, FIGURE 3-52) bushing inside diameter. The standard diameter is 0.749 to 0.750 in. (19.036 to 19.060 mm), with a limit of 0.752 in. (19.10 mm). lf measured value exceeds limit, replace rocker arm. d. Clearance between rocker arm shaft 00 and rocker arm bushing ID standard value is 0.0016 in. (0.04 mm). If clearance exceeds 0.008 in. (0.20 mm), replace either rocker arm shaft (18) or rocker arm (12, 14, 16, and 17). 3-105
