<br />1.
<br />Install disc springs on cable system using spherical washers to align
<br />discs to stud. Discs shall be installed front to front as shown in Disc Spring" detail.
<br />Install Cable Yield Indicator and
<br />Spherical Washers on
<br />the restrainers
<br />as shown in "Cable End Anchorage detail.
<br />2.
<br />Place thread locking system on
<br />stud prior to setting
<br />the cable.
<br />J.
<br />Tighten the cable until the disc
<br />springs collapse and
<br />there is
<br />no disc gap remaining between
<br />the discs. The cable
<br />should be approximately straight
<br />with no sag.
<br />4.
<br />Place thread locking system on
<br />stud after tightening
<br />the cable, but before backing
<br />off the nut. Back off the nut
<br />at a distance equal to maximum additional amount
<br />that the hinge joint is expected
<br />to open as shown in
<br />'Table A'.
<br />NOTE: If the cable needs to be secured from turningg while tightening,
<br />use double nut locking technique on the stud fo protecf the t1ireads.
