1. Install moveable sheave with spacer washers.
Important: At least one spacer washer must be
installed. Teflont bushings are self-lubricating.
Do not apply oil or grease to the bushings.
2. Install spring, inserting spring tab into proper hole
in moveable sheave.
3. Insert spring tab into proper hole in helix. See
specifications at the beginning of this section.
The driven clutch, helix/moveable assembly has
several different spring locations which affect clutch
shifting and RPMs. The greatest amount of spring
tension will raise engine RPMs during clutch upshift
and allow quicker backshift or downshift when pulling
or negotiating a hill, for example. The least amount of
tension will create a slower downshift and a harder
upshift.
