9. Torque the jam nuts to 20-25 FT-LBS. (27.2 - 34.0 Nm).
Tensioning Cable
Cable should have enough tension so it stays seated into the pulley but not so tight that it pulls the head plate off
the weight plate below it.
1. If the head plate has lifted, loosen the jam nuts at the terminations and loosen the threaded plugs a half turn
until the head plate comes to rest on the weight plate below. Check that the threaded plugs are engaged at
least 1/2” (12.7mm) at each termination.

2. Ensure that the weight stack selector pin can pin into each weight plate.
3. Tighten jam nuts to 20-25 FT-LBS.
Strength Cable Wear Guidelines
FRACTURES:
Casing can crack or fracture under strains during use.
Any crack in the casing merits cable replacement even
if no wire rope is exposed.
Be especially observant for fractures near the
components on the cable assembly - IE. Nylon Ball, Nico
Loop, Threaded Plug, etc.
TWISTING/BINDING:
Inspect casing to ensure wire rope is not twisting within
its casing. Any sign of the cable twisting should be
replaced immediately.
BULGING:
Internal wire rope strands can break within and coil
causing a bulge to appear. Cable should retain same
outside diameter throughout.
