Temporarily mount the steering wheel on the steering shaft. An alternative, shown, is to fabricate a lever arm with nut. The arm's spring scale hole is drilled to match the radius of the steering wheel. Before testing the worm bearing adjustment, grease the sector bearings and temporarily install the sector shaft with side cover. Keep the sector adjustment loose to prevent any drag. Worm bearings require a 3/8- to 5/8-pound pull at the steering wheel rim. Pull at right angles to the spokes.
