Part Removal & Replacement - Signode 4A1-114 Operation, Parts And Safety Manual

PART REMOVAL AND REPLACEMENT
GRIPPER, GRIPPER SPRING, GRIPPER PLATE
1. To remove the gripper and the gripper spring (20 and
22), drive the roll pin (21) out of the gripper using a
3/16" pin punch. Pull the gripper and gripper spring
off the gripper shaft. Inspect and replace as required.
Before reassembling, clean the exposed end of the
gripper shaft and lubricate using light machine oil. Do
not use grease. Reassemble in reverse order.
2. To replace the gripper plate (29) remove the two
gripper plate screws (31) and lift the gripper plate out
of the base. Be careful not to lose the shims (30)
beneath the gripper plate. Before installing a new
gripper plate, blow any dirt out of the hole in the base.
The gripper plate must be installed flush to 1/64"
above the base surface as shown in Figure 1. Apply
one drop of Loctite sealant #242 to each screw.
Reassemble in reverse order. After reassembling the
tool, do not use for 12 hours to permit Loctite sealant
to harden.
The top of the gripper plate must be only slightly above the top of the base. Failure to
install the gripper plate properly can cause a loss of strap tension.
TENSION HANDLE ASSEMBLY, WINDLASS SHAFT, AND RATCHET WHEEL.
1. Remove the retaining wire (19) from the windlass knob (17). Remove the cap screw (18) from
the windlass shaft (14). Pull the windlass knob off the end of the windlass shaft.
2. Slide the windlass shaft out of the base (32) and lift out the tension handle assembly. The
ratchet wheel can then be removed and inspected.
3. To remove the handle pawl (10) from the yoke
handle weldment (2), first remove the Klipring
Truarc (7) from the slot on the pawl pin (5). Press
the pawl pin out of the handle yoke by pushing on
the pin from the Truarc side of the pin. Once the
pawl pin is removed, remove the handle pawl
aligning set screw (3). The pawl cam, handle pawl,
pawl spring and spring washer (6, 10, 9 and 8) can
now be removed and inspected. Before
reassembling, clean all parts thoroughly in
solvent, particularly the hole in the handle yoke for
the handle pawl. Lubricate all moving parts with
light machine oil and reassemble in reverse order.
