TM 5-3895-374-24-1 Sure - Grip Sheave- Bushings Installation Instructions Before beginning installation, identify the bushing as follows:  Sizes JA through SK manufactured from “Sinstell” All but Size JA have provision for a setscrew over the keyway.  IMPORTANT Wedging the bushing to spread it during placement on the shaft could damage the bushing.  DO NOT wedge these bushings.  Sizes SH through SK manufactured from steel do not have a keyway setscrew.  Sizes SF through S are made from cast iron or ductile iron. The Sure-Grip tapered OD-type interchangeable bushing offers flexible and easy installation while providing exceptional holding power. To ensure that the bushing performs as specified, it must be installed properly. To Install: IMPORTANT: DO NOT USE LUBRICANTS IN THIS INSTALLATION 1 Thoroughly Inspect the bore of the mating part and the tapered surface of the bushing. Any paint, dirt. oil, or grease MUST be removed. Fig 1 Standard Mounting Fig. 2 Reverse Mounting 2  If following the STANDARD MOUNTING procedure and  placing  the  bushing  flange  toward  the  motor, place the bushing on the shaft, see Fig 1, bushings NOT  made  of  Sinsteel  may  require  slight  wedging to   slip   on   the   shall.   To   wedge   them,   insert   a screwdriver  into  the  sawcut  through  the  flange  of the bushing.  DO NOT wedge Sinsleel bushings, as this may damage them.  Place the bushing and its key on the shaft and position them for correct axial alignment of the drive. Place the mating part on the bushing,  aligning  the  drilled  holes  in  the  part  with the threaded holes in the bushing On M through S bushings,  the  mating  part  and  bushing  MUST  be assembled so the two threaded holes in the mating part are located as far as possible from the sawcut In  the  bushing  Insert  the  cap  screws  through  the mating part hub into the bushing flange and finger- tighten them. 3      If   following   the   REVERSE   MOUNTING procedure,  assemble  the  bushing  loosely into the mating part and insert cap screws through the drilled holes in the mating part and thread them into the bushing, see Fig. 2.Place  the  assembly  and  its  key  on  the shaft.    Bushings  NOT  made  of  Sinsteel may require slight wedging to  allow  a  slip fit   into   position.      To   wedge,   insert   a screwdriver into the sawcut in the bushing flange. DO NOT wedge Sinsteel bushings,   as   this   may   damage   them. Position  the  assembly  for  axial  alignment Fig. 3 4  Will the drive properly aligned.  tighten all cap screws evenly and progressively in rotation to the  torque  values  listed   in   the   table   below When   the   screws   are   tighten   properly,   the listed   torque   value   will   remain   on   all   cap screws   and   there   will   be   a   slight   group between  the  flange  of  the  bushing  and  the lace  of  the  mating  hub.  DO  NOT  attempt  to tighten  enough  to  close  this  gap.    Recheck drive     alignment.     If     the     bushings     have setscrews    over    the    keyways,    insert    and tighten them.
