The supplied V56340 tensioning pulley differs visually
from the pulley installed in the vehicle and seems as
though it cannot be correctly tensioned.
In the original equipment, the pulley design as in Fig. 1 is
installed. A slightly modified tensioning pulley is supplied
for the aftermarket – see Fig. 2.
To set the tension correctly, the new design first has to
be compressed as far as possible using the new nut on
the stud bolt such that the “stirrup” fitted on the reverse
of the baseplate can slide past the casting (maximum
load stop): see Fig. 3.
