Step 2:

• Slide the neck completely into the datum block, aligning keys on the neck to the keyway in the datum block.
• Turn the neck completely clockwise against the shoulder.
• To secure the neck, use a 5/16-inch Allen wrench to tighten the socket head cap screw (SHCS) on the front of the datum block.

Step 3:

• Push the check pin toward the gauge point.
• The check pin should insert into the mating hole on the gauge point.
• Slip the bending handle onto the gauge point and bend until it is aligned with the check pin.
• Remove the neck from the datum block and gauge point from the neck.
• Reinstall the consumables.
