How to maintain the motorcycle chain?

The chain (motorcycle chain) can be divided into motorcycle sleeve chain, motorcycle roller chain, motorcycle seal ring chain (oil seal chain, also divided into O-ring seal chain and X-type seal ring chain), tooth Shaped chain (silent chain). Then what should we do to maintain the motorcycle chain?

According to the points of use on the motorcycle, the motorcycle chain can be divided into two types: the chain used inside the engine and the chain outside the engine. Most of the chains used in motorcycle engines are sleeve chains. The sleeve chain used in the engine can be divided into timing chain or timing chain (cam chain), balance chain and oil pump chain (engine with large displacement). The motorcycle chain used outside the engine is used to drive The rear drive chain (or drive chain), the majority of the use of roller chain (individual specifications of the chain, such as 219h or 05ma also used as a drive chain). High-quality motorcycle chain (motorcycle chain) includes a full range of motorcycle bush chains, motorcycle roller chains, motorcycle seal chain and motorcycle tooth chain (silent chain).

Motorcycle O-ring chain (oil seal chain) is a high-performance transmission chain specially designed for motorcycle road racing cars and racing cars. The chain comes with a special o-ring to seal the lubricant in the chain from dust and dirt. The color of the chain can be shot peening, golden (copper plating) and silver (nickel plating), among which the copper plated/nickel plated motorcycle chain is usually copper plated or nickel plated on the inner and outer chains of the chain, and all parts can be fully copper plated. Or nickel-plated oil seal chain This chain is filled with a certain amount of grease in the middle of the pin sleeve, which can reduce the wear and prolong the service life; and due to the sealing effect of the “O” ring, it can prevent sediments from entering the chain hinge joint.

Correctly adjust the motorcycle chain (1) timely adjustment to maintain the tightness of the motorcycle chain is 15mm ~ 20mm appropriate, often check the buffer bearing and grease on time, because the bearing working environment is poor, once lost lubrication, The damage may be extremely great, once the bearing is damaged, it will cause the rear gear plate to tilt, and the light will make the side chain chain wear, and the weight will make the chain fall off easily.

(2) When adjusting the chain, in addition to adjusting the scale of the frame chain, it is also necessary to observe whether the chainring and the chain are in the same line, because the frame or the rear wheel fork is damaged. After the frame or the rear fork is damaged and deformed, adjusting the chain according to its scale will enter a misunderstanding, mistakenly thinking that the chain chain is on the same straight line. In fact, the linearity has been destroyed, so this check is very important (best adjustment Remove the chain box. If any problem is found, it should be immediately corrected to eliminate the trouble and ensure that everything is safe.

(3) When replacing the chainring, be sure to pay attention to replacing the materials with good quality craftwork (general contractual repair station accessories are more regular), so that it can extend its service life. Must not be greedy and buy unqualified products, especially gear discs are not qualified, more eccentric loss of the garden, once the purchase of replacement, will find the chain suddenly loose and loose, the consequences are unpredictable.

(4) Always check the clearance between the rear wheel fork cushion sleeve and the fork and wheel fork shaft, because the place requires the lateral clearance of the rear fork and the frame to be rigorous, and the up and down movement is flexible, and only in this way can the rear wheel be guaranteed. The fork and the frame can be formed integrally and do not affect the shock absorption effect of the rear shock absorption. The connection between the rear fork and the frame is achieved through a fork shaft and a cushion sleeve. Since the quality of the domestic cushion sleeve product is not yet stable, it is particularly prone to loosening. Once the binding site has loosened, the rear wheel will be displaced under the control of the chain when the motorcycle is started or accelerated. The size of the displacement is determined by the degree of damage of the cushion rubber sleeve. At the same time, the rear wheel has a noticeable flick of movement during acceleration and deceleration. This is also one of the important causes of damage to the chainring. Should be more inspections and attention.

(5) Regularly clean the chain and tooth plate, add grease in time, add rain, snow and muddy roads, and strengthen chain and tooth plate maintenance. Only in this way can the service life of the chain tooth plate be extended.
