Assembly of the Counter Torque Handle to a Facilitator will
provide the instrument needed for application of counter
force during final tightening. To assemble these instruments,
depress the button on the Counter Torque Handle and slide it
over the proximal end of a facilitator. The Counter Torque
Handle will engage and retain the facilitator. These
instruments can be assembled such that the handle will be
parallel or perpendicular to the rod. A light pull can be
applied to the facilitator to ensure that the Counter Torque
Handle has properly engaged and locked the Faciltator.
Place the counter torque assembly over the head of the
screw. Insert the Key Inserter/Tightener or X25 Inserter/
Tightener through the counter torque assembly and engage
the corresponding Poly Lock, Rod Lock, or Unitized Set
Screw. Tighten until there is a tactile release which indicates
that the required 80in-lb (9Nm) of torque has been applied.
Repeat this process for all levels.
If required, the Torque Wrench Handle (2770-40-510), found
in the EXPEDIUM 5.5 System, can be used with the Torque
Handle Adapter (2997-04-325) to final tighten Correction
Keys or Unitized Set Screws.
Caution: Care must be taken to ensure that the Torque
Wrench Handle is set to 80in-lb (9Nm).
If a Correction Key or Unitized Set Screw needs to be
loosened or removed after having been tightened to
80in-lb (9Nm), use the counter torque assembly and X25
Inserter/Tightener to first loosen the Rod Lock. Then, with
the counter torque assembly still in place, use the Key
Inserter/Tightener to loosen the Poly Lock.
NOTE:
If it is necessary to release the Rod Lock, retighten
the Poly Lock prior to retightening the Rod Lock.
