idler  tensioner  pulley.  The  idler  tensioner

 

pulley  also 

extends the contact area between V-belt and pulley. 
 
When the generator is not connected to the engine block, 
but  mounted  next  to  the  engine  block  a  V-belt  tensioner 
must be applied. To prevent damage induced by vibrations 
the mounting bracket parts must be installed without build-
in tension.

Be  aware  that  while  changing  the  load  on  the 
generator  the  belt  can  strike  violently  on  the 
non-pulling side. 

 
Tighten  the  belt  according  to  the  instruction  of  the 
manufacturers  recommendations.  A  belt  too  tight  or  too 
loose will reduce the life of the belt and generator and will 
impair the performance of the generator.  

 
 

Pulleys 

A poly V belt pulley with 6 groves and a diameter of 60 mm 
and  an  overhang  of  5  mm.  (refer  to  the  figure  14).is 
recommended.  A  6-grove  pulley  50  mm  is  the  minimum 
diameter that can be applied. 
 
Other pulleys are available on request. 
When applying a double grove classic V-belt, a diameter of 
75 mm is recommended. In this case 70 mm is the minimum 
diameter. Refer to the table for available pulleys:
