AXYS CLUTCH OFFSET / FLOAT
ADJUSTMENT
1. Determine the direction the driven clutch needs to be
adjusted using the Clutch Alignment tool.
2. Remove the driven clutch bolt, flat washer, float
washers and spacer.
3. Add or remove from the offset washers / bushing
stack on the jackshaft behind the driven clutch shaft.
Reference the Offset Washers / Bushing Table. Any
combination of these washers / bushing can be used
to set the offset, but at least one .120 washer must be
installed between the driven clutch and bearing on
the jackshaft.
