Overview

Wheel 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 air frame vibration


McFarlane's wheel 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 McFarlane 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. McFarlane wheel 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.

  • Portable - small enough to fit in your tool box

Reviews

You need to be aware that this tool is just the central rod. The kit does not contain the spacers that are needed to center the rod on the bearing center line of a typical light aircraft wheel. I originally wanted to use the balancing tool to balance the front wheel of my Socata TB20. It turned out to be entirely unsuitable for that purpose.

Q: My understanding is this is for 3/4 axle wheels - and additional bushings are required for largre axle sizes. Is this correct - and if so does spruce sell those additional bushings?

There are not bushings for this tool. Tool129 (part # 05-12922) has options for larger bushings.
