The front wheel bearings on our machines are of the cup and cone type. The adjusting cone is secured by a lock nut and is on the near side of the machine (opposite side to front brake). To adjust, the near side spindle nut should be slacked off. Then slack off the cone lock nut and carry out the necessary adjustment of cone. Tighten up lock nut securely against cone and then tighten spindle nut. When correctly adjusted the slightest amount of play should be perceptible on the rim of the wheel.
