Excessive wear on both sides of the control cable pulley groove is evidence of
- pulley misalignment.
- excessive cable tension.
- cable misalignment.
Explanation from PART66Online
If a pulley is misaligned, the cable enters and leaves the groove at an angle and rubs against both side flanges, producing wear on both sides of the groove. Excessive tension or a fairlead/cable problem tends to wear the groove base or chafe the cable, not symmetrically wear both groove flanges.
