The process of removing the flange bushes is delicate yet easy.

Let’s say you are to remove the flange bushing from an airplane wheel.

When the edge of the tyre can touch the side of the yoke due to wear, you should replace a new set of bushings.

It is a relatively straightforward operation that may be completed using standard modeling software.

Cut a groove in the inside diameter of one of the bushings with a tiny saw-like tool. You don’t have to do both sides.

It is recommended that you do not cut through to the aluminum wheel. What you’re doing is releasing the tension in the bushing’s press fit with the wheel.

Take any sharp thin knife blade and slide it under the flange after you’ve cut a groove most of the way through.

With a twisting motion of the knife blade, you should be able to pop the bushing out at this point. Cut the groove a little deeper if the bushing doesn’t pop out.

Find a drill, wood dowel, or anything else that has a flat end near the internal diameter of the hub with the bushing removed from one side.

Fit your rod into the wheel center hole where you just removed the bushing and hold it against the inside flange of the remaining bushing with your rod as a punch.

The second bushing will be driven out of the wheel by tapping the end of the 3/8 rod.

Remove the rough edges on the inside of the axle bore. You can do it with a fine round file or sandpaper on a dowel if you cut into the wheel in one go.

The new bushings should then be pressed into the wheel.

You can do it in a variety of methods.

Close the vise after making sure the bushing is aligned directly above the center hole in the wheel. You can also use a hammer to tap it in, but you’ll need to put something between the bushing flange and the hammer. Do not pound the bushing flange directly.
