<br />RESTRAINER INSTALLATION PROCEDURE
<br />1. Install disc springs on Hinge side of cable system using spherical washers to align
<br />discs to stud. Discs shall be
<br />installed front to front as shown in "Disc Spring" detail.
<br />Install Cable
<br />Yield Indicator and
<br />Spherical Washers on the Pier side of restrainers
<br />as shown in
<br />" Coble Unit detail.
<br />2. Place thread
<br />locking system on
<br />Hinge side stud prior to setting the cable.
<br />3. Tighten the cable from Pier side
<br />of restrainer until the disc springs collapse and
<br />there is no
<br />disc gap remaining
<br />between the discs. The cable should be approximately
<br />straight with
<br />no sag.
<br />4. Place thread
<br />locking system on
<br />Pier side stud after tightening the cable, but before
<br />backing off
<br />the nut. Back off
<br />the nut at Pier side a distance equal to maximum additional
<br />amount that
<br />the hinge joint is
<br />expected to open as shown in Table A.
<br />NOTE: if the cable needs to be secured from turning while tightening,
<br />use double nut locking technique on the stud to protect the threads.
