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
