10.9.8 Option ga
Generator drive belt maintenance
Correct belt tension is extremely important for the function of the generator and the operational life
of the belt itself.
Use a tensioning mechanism with spring strut, swing frame and tension pulley to ensure correct
belt tensioning. The spring force pushes downward the swing frame with tensioned pulley between
the pulley of the crankshaft and the pulley of the generator of the belt drive and thus generates the
required belt tension.
Material Ratchet 1/2 inch
Spare parts (if required)
