The freewheel clutch insert element requires axial constraints on both sides.
Hardening and grinding of the mating parts are not necessary. Thoroughly clean (grease free) the mating parts in the vicinity of the freewheel clutch as well as the freewheel clutch’s rings before making the press fit.
Freewheel clutch insert elements are not self-centering. External bearing support to define the gap between mating parts (inner and outer rings) is necessary.
