The maintenance of the front shock absorber of Chongqing motorcycle is as follows:

(1) First of all, popularize some small knowledge: In China, common types of shock absorbers with displacements of 50, 70, 80, 90, 100, 125, 250, and 750ml can be roughly divided into spring type and spring type in structure. Hydraulic type. Motorcycle shock absorbers with a displacement of 50ml are mainly spring type, and motorcycle shock absorbers with a displacement of 70ml and above are mainly spring hydraulic type. The spring type shock absorber mainly relies on the spring to buffer the vibration, and relies on mechanical friction or air damping, so the damping effect is poor. However, due to its advantages of no oil leakage, large strength safety factor, simple structure, convenient manufacture, convenient maintenance, and few failures, it is still widely used.

(2) Tools required for maintenance of Chongqing motorcycle front shock absorber:

Remove the shock absorber wrench, remove the rubber cover at the upper end of the front shock absorber, pull out the stop ring, take out the cover, gasket, inner sleeve, shock absorber spring and other parts, and then pour out the hydraulic oil in the shock absorber. Clamp the shock absorber with a vice (be careful not to clamp too tightly), hold the piston rod with a wrench, loosen the fastening connecting bolt at the root of the outer fork tube with an Allen wrench, then take out the inner fork tube and other parts, and install in the reverse order of removal. The front shock absorber cleaner can remove oil and make the shock absorption smoother.

The assembly points include:

(1) When installing the oil seal, the main lip should face the inside of the outer fork tube, and the dust lip should face outward (that is, the numbered side of the oil seal should face outward). Apply a small amount of grease to the lips, and then use a wooden block and a hammer (or screw in with a special tool) to gently drive the oil seal into the outer fork tube.

(2) All parts need to be cleaned before assembly.

(3) The main lip of the oil seal shall not be scratched.

(4) When installing the oil drain plug, do not omit the sealant or gasket.

(3) How to adjust the front shock absorber of Chongqing motorcycle.

adjust the benefits of motorcycle suspension:

On our motorcycles, there are two suspension parts: one is located in the front wheel, usually called the front fork; the other is in the rear wheel, usually called the rear shock absorber. Just like a car, the suspension has two very important functions. We all know that rough terrain will bring vibration to the body, and the suspension will make driving more comfortable; at the same time, keep the tires in contact with the ground to ensure that the tires are on the ground. Output power. However, unlike cars, the suspension of motorcycles also greatly affects the steering stability and turning stability of motorcycles.

A suspension usually consists of two parts: a spring and a shock absorber. The spring is the main component of the suspension. This spring is like the spring in a ballpoint pen, but it is much stronger. The spring absorbs the impact of the ground through the elastic component to ensure the contact between the tire and the ground; the damper is a device used to control the tightness and elasticity of the spring.

The damper is like a gas pump filled with oil. The speed at which the air pump moves up and down depends on the size of the through hole and the viscosity of the oil. All cars have springs and shock absorbers. The spring is hidden on the front fork, and the rear shock absorber is exposed. The suspension on the front and rear wheels works separately and can respond separately according to road conditions and driving modes.
