Feed Rolls
Refer to feed roll kit chart in the Appendix chapter for
the proper selection and ordering of feed roll kits. Kit
includes a bearing roll, a drive roll, an input wire guide,
and an output wire guide for a specific wire type and
size.
NOTE
All grooved feed rolls have their wire size
or range stamped on the side of the roll.
On rolls with different size grooves, the
outer (visible when installed) stamped wire
size indicates the groove in use.
Bearing feed rolls are installed by unscrewing the
upper retaining knob and removing the idler gear. The
bearing feed roll retaining knob is then removed from
the idler gear, and the bearing feed roll is placed over
the lobes on the idler gear. The bearing feed roll
retaining knob is replaced, and this assembly is
returned and secured with the upper retaining knob.
Drive feed rolls are installed by removing the lower
retaining knob, placing the drive feed roll over the
lobes on the drive gear, and securing with the lower
retaining knob.
NOTE
Installation of all styles of feed rolls for
this feeder is identical.
