Mounting tipes:  
  Standard mounting:  

   

The pull-up bolts, by being through the pulley hub and tapped into the adjusting cone, exert pressure on the pulley hub against the bushing cone, and remain opposite the operator.
   
  Reverse mounting:  
  The pull-up bolts, by being through the adjusting cone and tapped into the pulley hub, exert pressure on the bushing cone against the pulley hub, and remain opposite the operator.
   
  Special mounting:  
  It is employed whenever the pulley design does not allow the use of the mounting types already described. Bolts remain reversely as referenced to the operator. For the rest, the above applies.
   
  Demounting:  
  1. Loose and remove the screws.
  2. Lay the screws into the pulling holes.
  3. Tighten the screws until the pulley is freed from the shaft.
  4. Remove the pulley from the shaft.
  WARNING: Do not use anti-seize lubricant on the tapered cone surfaces in order not to damage the pulleys.
