  • Page 57: Final Checklist

    FINAL CHECKLIST BEFORE RUNNING YOUR XXX-NT AD2 for the first time, you should run down the following checklist — in order — and complete the listed tasks. This simple checklist will help to make the first run with your new XXX-NT AD2 truck much more enjoyable.
  • Page 58 THE CLUTCH BEARINGS included in the kit contain a special lubricant. If the clutch bearings need to be replaced it is important to only replace them with the Team Losi clutch bearings LOSA6913. If a different bearing is used, or if you oil the standard clutch bearings, the lubricant can migrate into the clutch.
  • Page 59 CHANGING THE GEARS on your XXX-NT AD2 is a very simple process. There are several different clutch bell gears available for the XXX-NT AD2. When changing to a different size gear, you will need to re-set the gear mesh. To adjust the gear mesh, loosen the four screws securing the engine mounts to the chassis and reposition the engine.
  • Page 60 The following is our experience with how the length of the camber link will typically affect the handling of the XXX-NT AD2. A longer rear camber link will usually result in more rear traction. With a longer link, the truck can start to drive more square, or point-to-point.
