Drive Wheel Bushings from emachineshop.com
Excellent service from emachineshop.com to fabricate these custom specified bushings that go inside the drive wheel hub. They are 13/16-inch outside diameter and 7/8-inch inside diameter with a slot cut on one side of the cylinder to let them expand against the hub when I insert the Trantorque GT (not a mini, as previously reported). These took under 3 weeks from emachineshop.com and are just as spec’d. They fit perfectly into the wheel hub, as you can see with one of them installed.
Next on tap: the rest of the hardware to complete the azimuth drive.
