How to adjust the motorcycle direction pillar bearing clearance?

Motorcycle direction column broke what symptom to have?

When the motorcycle is running, if it is found that the motorcycle is not flexible, and it is easy to deviate to a certain side or direction column, abnormal sound occurs.Motorcycle steering column has the role of auxiliary steering, and through the front shock absorption, front wheel and frame, handlebar, motorcycle control, steering, etc., is to be completed through it.  The motorcycle with the main bracket support, so that the front wheel lifted, and gently shake the fork, if there is obvious loosening, should be adjusted.

If the steering bearing is damaged, the steering will not be flexible when driving, but also emit abnormal sound.  The following is a related introduction:  

Steering shaft: the function of the steering shaft is to transfer the steering moment that the driver acts on the steering wheel to the steering gear. Its upper part is fixedly connected with the steering wheel, and the lower part is connected with the steering gear.  The steering shaft passes through the steering column tube and is supported on bearings and bushings in the column tube.  Some steering shafts not only have a certain stiffness, but also have the function of absorbing energy to prevent injury.  

The size of the bearing clearance of the motorcycle direction pillar directly affects the straightness of the vehicle. When the clearance is too large, the handlebar is prone to jitter. The clearance is too small, the handlebar steering is not flexible. Laborious operation accelerates the wear of ball and upper and lower bearings. Therefore, if the bearing clearance of the direction pillar is not suitable, it should be adjusted in time, and if it is caused by the wear of the upper and lower bearings, it should also be repaired in time.

The method of adjusting the bearing clearance of the directional pillar is accomplished by adjusting the tightness of the bearing nut. Turn the bearing nut clockwise, the clearance becomes smaller, turn the bearing nut counterclockwise, the clearance increases. If the front wheel is lifted and the handlebars are placed in the middle position, it can use the weight of the front wheel to reverse to the side. But it is not too flexible, that is, the gap is appropriate. In the absence of front wheels, push the front fork sleeve by hand and the front fork should be able to rotate flexibly around the directional column. If you push it to where it stops, it means that the bearing clearance is too small, and the bearing nut should be loosened. After clearance adjustment, the front fork nut should be locked tightly to prevent loosening.
