Important fitting notes: rope clutches

  • When fitting ensure a fair lead straight through the clutch to prevent wear to side plates and/or reduced load capabilities.
  • For best performance site clutch approximately 2ft (600mm) forward of the winch to ensure a fair lead both vertically and horizontally.
  • Use barton deck organisers forward of the clutch to gain perfect alignment.
  • Always use a bolt-through fastening with a suitable sealant.
  • A drilling template is provided on oir packaging for your convenience.
