TM 5-3895-374-24-1 Sure-Flex Installation Instructions (continued) Different coupling sleeves require different degrees of alignment precision. Locate the alignment values for your sleeve size and type in Table 2 below. 5. Check  parallel  alignment  by  placing  a  straightedge  across  the  two  coupling flanges   and   measuring   the   maximum   offset   at   various   points   around   the periphery  of  the  coupling  without  rotating  the  coupling.  If  the  maximum  offset exceeds the figure shown under "Parallel" in Table 2, realign the shafts. 6. Check  angular  alignment  with  a  micrometer  or  caliper.  Measure  from  the outside of one flange to the outside of the other at intervals around the periphery of   the   coupling.   Determine   the   maximum   and   minimum   dimensions   without rotating the coupling. The difference between  the  maximum  and  minimum  must not   exceed   the   figure   given   under   "Angular"   in   Table   2.   If   a   correction   Is necessary, be sure to recheck the parallel alignment.

Note. Values shown above apply if the actual torque transmitted is more than 1/4 the coupling rating For lesser torque, reduce the above values by 1/2. * Type H and HS sleeves should not be used as direct replacements for EPDM or Neoprene sleeves (1) Value when using 6J flanges is 2 125 7. If the coupling employs the two-piece sleeve with the wire ring, force the ring into its groove In the center of the sleeve. It may be necessary to pry the ring Into position with a blunt screwdriver. 8. Install coupling guards per OSHA requirements. CAUTION: Coupling sleeves may be thrown from the coupling assembly with substantial force when the coupling Is subjected to a severe shock load or abuse. T. B.
