TM 5-3895-374-24-2 FORM 741E Sure- Flex® Couplings Installation Instructions Sure-Flex   flanges   (outer   metallic   parts)   and   sleeves (inner  elastomeric  members)  come  in  many  sizes  and types.  First, determine the size and type of components being  used.    Remove  all  components  from  their  boxes, and  loosely  assemble  the  coupling  on  any  convenient surface.    (Do  not  attempt  to  install  the  wire  ring  on  the two-piece   E   or   N   sleeve   at   this   time.)   Also   check maximum   RPM   values   in   Table   2   against   operating speed.    All  rubber  sleeves  (EPDM  and  Neoprene)  have the   same   ratings   for   a   given   size   and   may   be   used interchangeably.    However,  because  rubber  and  Hytrel sleeves   have   completely   different   ratings,   they   never should be used interchangeably. 1.    Inspect all coupling components and remove any protective   coatings   or   lubricants   from   bores,   mating surfaces and fasteners.  Remove any existing burrs, etc. from the shafts. 2.    Slide one coupling flange onto each shaft, using snug-fitting keys where required.  With the  Type  B  flange,  it  may  be  necessary  to  expand  the bore  by  wedging  a  screwdriver  into  the  saw  cut  of  the bushing. 3.    Position the flanges on the shafts to approximately achieve the G1 dimension shown in Table 2.    It  is  usually  best  to  have  an  equal  length  of  shaft extending into each flange.  Tighten one flange in its final position.    Refer  to  Table;  1  for  fastener  torque  values. Slide  the  other  far  enough  away  to  install  the  sleeve. With a two-piece sleeve, do not move the wire ring to its final   position;   allow   it   to   hang   loosely   in   the   groove adjacent to the teeth, as shown. 4.    Slide   the   losse   flange   on   the   shaft   until   the sleeve  is  completely  seated  in  the  teeth  of  each  flange, (The  "G1"  dimension  is  for  reference  and  not  critical.) Secure  the  flange  to  the  shaft  using  the  torque  values from Table 1. TABLE 1 - FASTENER TORQUE VALUES (ft.-lbs.)
