Spring Torsional Pre-Load
To check spring pre-load adjustment, use spring
scale hook (P/N 529 0065 00) and a spring scale.
Install the hook on the sliding half, making sure
the spring scale is perpendicular to the pulley axle.
Take a measurement when opening driven pulley
and another one when driven pulley begins to close
after a rotation of 10 mm (3/8 in). Spring pre-load
is the average measurement between these 2.
