General Safety and Maintenance Manual: Weekly Inspection 17
Inspect Cables, Connections, and
Tension
Each week, give the cables and connections a thorough inspection
and check cable tensions. The following lists the specific things you
need to inspect:
• Check the cable termination at the weight stack. Make sure that the
cable bolt is threaded at least a minimum of seven turns into the
selector stem or a minimum of ¹₂-inch (13 mm), so that there is no
more than ³₄-inches (19 mm) between the top of the jam nut and
base of the bolt head. Check and adjust accordingly. Also make
sure that the locking jam nut is tight against the selector stem.
• Check the cable, especially near all pulleys, wheels, and cams.
• Check the cable as it terminates at the cam, which is stationary on
most equipment. Inspect the bolt passing through the cam end
fitting to be sure the two jam nuts are tightened against each other.
Also, check the entire cable routing to verify that there is no
interference with any structure.
• Inspect the ball end of the cable where the cable connection rests
in the clevis housing.
• Ensure that each cable is properly adjusted and tightened at the top
of the weight stack.
• Check cable pulleys, end connections, and end fittings. Make sure
all connections are tight, adjusting cable tension as necessary.
