The drive assembly comes
equipped with factory

tion drive rolls. Be sure that all

rectly.
Combination drive rolls consist of
two different sized grooves. The
stamped markings on the end sur-
face of the drive roll refers to the
groove on the opposite side of the
drive roll. The groove closest to the
carrier gear is the groove for the
wire size viewed on the end surface
of the drive roll.
