Removing and Replacing the Driver (Figure 18)
If the staples produced have crowns that are buck-
led or corners that stick up, or if wire is jamming
between the Driver and Driver Bar, the Driver may
have to be reversed or replaced. Swing the Wire
Holder Retaining Spring (G20183) off of the Wire
Holder Assembly (G20559BA) and out of the way.
Remove the two (2) Driver Retaining Screws
(G20153) securing the Driver* to the Driver Bar
(G20151) and slide the Driver out of the Bender
Bar.* The ends of the Driver are identical so when
one end is worn or chipped, it can be reversed. If
both ends are worn, replace the existing Driver with
a new one. Add a little threadlocker to the Screws
before returning them to the Driver Bar. Replace the
Wire Holder Assembly and Wire Holder Retaining
Spring.
Removing and Replacing the Latch and
Latch Spring (Figure 19)
If multiple pieces of wire are being loaded in the Wire Holder Assembly (G20559BA) and not being
formed, the Latch (G20149) and/or Latch Spring may have to be replaced. Remove the Cap Screw
(G20171) on the back of the G8 Stitcher Head to release the Driving Slide Assembly (G20162A or
G20320A). Once the Slide has been released, swing the Wire Holder Retaining Spring out of the way
and remove the Wire Holder Assembly. Use the
Adjustment Knob Assembly (G20228A) to move the
Cutter Block out slightly so the Bender Bar
Assembly can be removed from the bottom of the
head. Remove the Bender Bar Friction Bushing
(G20161), the Bender Bar Friction Spring (G20160)
and the Bender Bar Friction Plug (G20159) from the
back of the Bender Bar. Loosen the Set Screw
(G20156) in the front of the Bender Bar and remove
the Supporter Pivot Pin (G20155) and Supporter
Assembly (G20154A). Compress the Latch and
slide the Driver Bar (G20151) out the bottom of the
Assembly. Remove the Machine Screw (G20224)
securing the Bender Bar Latch Spring (G20150) and
remove the Spring. Slide the Latch out of the
Assembly as well.
Replace the Latch Spring and Machine Screw.
Slide the Latch in through the right side of the Latch
