Balance Cable & Pulley Inspection Procedure
Please make note of the precautions before starting the
inspections.
To inspect the balance cables and pulleys the
tension on the cables must be released to
enable these items to be correctly inspected
and lubricated.
Use gloves when handling Wire Ropes to
avoid injury from broken wires.
To properly assess wire ropes, you must bend
them to expose any broken wires, refer to
Diagram 23. Give special attention to the
sections that run over the pulleys; check both
the inner and outer running areas of these
sections.
