Wheel & Prop balance is important. Aircraft tires spin 1.6 times faster than car tires. Out-of-balance wheel cause a long list of maintenance problems:
  • Uneven tire wear
  • Premature bearing wear
  • Shimmy and resulting torque link damage
  • Destructive and distracting airframe vibration McFarlane's Wheel / Propeller Balancer is a suspension wheel balancer with a patented design featuring a pivot point that is easily adjustable on-the-fly for maximum balance sensitivity. It is small enough to fit in a tool box and doesn't require a bulky stand. The design is more precise than other static balancing methods, and allows the wheel to be balanced with the bearings and seals installed.

    It's fast and easy! Due to the horizontal balancing orientation, test weights can be temporarily set in place and easily adjusted while balancing. This eliminates the need to tape the test weights. The balancers are precision machined with a black, hard anodized finish, and come in an oiled wooden case. This is a lifetime tool that fits almost all light aircraft wheel/tire assemblies.
