Installation Process and Measurements:

  • Preparation: Clean the axle spindle and inspect it for any wear or damage.
  • Hub Mounting: Carefully slide the hub onto the spindle. Ensure it fits securely.
  • Bearing Installation: Install the appropriate bearings (3984 and 28682), which are not included in the hub package.
  • Securing the Hub: Install and tighten the wheel nuts to the manufacturer’s specified torque.
  • Brake Drum and Mounting Bolts: If using a drum, ensure it is compatible with the hub and install it along with the mounting bolts.

Typical Spacing Measurements and Tips:

  • Bolt Pattern Measurement: The hub features an 8 on 6.5″ bolt pattern, suitable for various heavy-duty trailer wheels.
  • Spindle Compatibility: This hub requires a #120 spindle for proper fitment.
  • Hub Capacity: Each hub has a load capacity of 6,000 lbs, suitable for 12K axles.
  • Regular Maintenance: Regular checks and maintenance of the hub are essential for optimal performance and safety.
