Skywheels rotor blade retention bolts and other adjoining hardware should be replaced at a minimum every 12 months, or as required.

The appropriate bolt length required varies by the thickness of the center section. Over the years, Skywheels has had three different center sections, and each requires a different-length bolt shaft for proper clearance.  The three center section versions by length include 3 ft. legacy (tower part hump is under the gel coat), 3 ft. (the half-round part is on top of a metal plate, new style), and 5 ft (the half-round part is on top of a metal plate, new style).

We've created a bolt retention replacement "kit" that includes the following AN hardware:

*AN bolts (qty 8)
*Washers (qty 16)
*Castle nuts (qty 8)
*Safety pins (qty 8)
