WELDING MECHANISM, DRIVE GEARS,
CLUTCH AND BRAKE

1.

Remove the idler gear (27) from the pin
(30) and examine both parts for wear.

2.

Remove the eccentric shaft (26) and
examine it for wear.

 
3.

Lift the slider link (48) from the gear
housing (72).  Examine the teeth on the
upper gripper (52) for wear.  The upper
gripper can be replaced by removing the
pin (51).  Make sure the pin faces the
teeth of the upper gripper (52) as shown.

4.

Remove the needle bearing (29) from the
casting by threading a 1/4-20 screw
through the bearing into spacer (86).
Clamp the screw head in a vise and
lightly tap the casting to extract the
bearing (See inset "A").

5.

Examine the teeth of the lower gripper
(78).  If the part is to be replaced, it may
be removed by first removing the
mounting screw (87) from underneath,
then punching it out from underneath
through the two holes. When reinstalling
a lower gripper, use Loctite "380 Black
Max" (Signode Part No. 274111) or an
equivalent instant adhesive to ensure the
lower gripper will be held securely.  Note
that mating surfaces must be free of dirt
and grease. 

NOTE: When using 380 Black Max adhesive,
directly follow the manufacturers cleaning
and preparation instructions.
