G8HD24C
(Bolt Mount/Crank Drive)
This G8 Head comes with a Rear Mounting Bolt (G20341), a Rear Clamp Pin (G20366) and a
Bonnet Stud Nut (HN1213) for mounting. The G8HD24C also comes with a Crank Drive Link
(G20340) and Driving Slide Assembly (G20320A) for driving the Head. Refer to Figure 4.
NOTE: Instructions may vary with other types of Bolt Mount/Crank Drive machines.
To attach the head, rotate the Drive Pulley manually on any Crank-Driven stitcher machine, like a
Bourg, Camco or Rosback until the stitcher’s Driving Crank is at the top of its stroke. Insert the Rear
Mounting Bolt into the hole of the Bonnet casting and
secure it with the Rear Clamp Pin. Engage the Crank
Drive Link (G20340) with the Driving Slide Assembly
(G20320A) on the back of the stitcher head. The
Driving Slide Pin must be inserted in the lower hole of
the Link. (The lower hole of the Link is the one
opposite of the oil hole.) With the Link held in a
vertical position, line the head up with the machine.
Engage the machine’s Crank Pin in the upper hole
of the Driving Shaft Connecting Link.

(Bolt Mount/Rail Drive)
This G8 Head comes with a Rear Mounting Bolt
(G20367), a Rear Clamp Pin (G20366) and a Hex Jam
Nut (G20170) for mounting. Refer to Figure 4.
NOTE: Instructions may vary with other types
of Bolt Mount/Rail Drive machines.
Insert the Rear Mounting Bolt into the hole of the Bonnet casting and secure it with the Rear Clamp
Pin. Position the Driving Slide Assembly Eccentric (G20320A) approximately where it will meet
up with the rails of the stitcher machine or a little lower. Line the Rear Mounting Bolt up with the
mounting hole in the stitcher machine and loosely secure the Bolt with the Hex Jam Nut. Push on
the Head’s Bender Bar until the cam on the Driving Slide Assembly lines up with the rail of the
stitcher machine.
