(1) It is advisable to adjust the tightness of the Classic Motorcycle Manufacturers chain in a timely manner to keep the tightness of the motorcycle chain between 15mm and 20mm. Check the buffer body bearing frequently and add grease on time. Because the working environment of the bearing is harsh, once it loses lubrication, the damage may be great. Once the bearing is damaged, it will cause the rear chainring to tilt, in the slightest case, the side of the chainring of the chainring will be worn, and in the heavy case, the chain will fall off.
(2) When adjusting the chain, in addition to adjusting the scale according to the frame chain adjustment scale, you should also observe whether the front and rear chainrings and the chain are in the same straight line, because the frame or rear wheel fork has been damaged. After the frame or the rear wheel fork is damaged and deformed, adjusting the chain according to its scale will lead to a misunderstanding. It is mistaken that the chainring chain is in the same straight line. In fact, the linearity has been damaged, so this inspection is very important (it is best to adjust the chain). Remove the chain box), if a problem is found, it should be corrected immediately to avoid future troubles and ensure that there is nothing wrong.
(3) When replacing the chainring, you must pay attention to the replacement of high-quality products with good materials and fine craftsmanship (generally, the accessories of special service stations are more formal), which can extend its service life. Don’t buy substandard products for cheap, especially unqualified chainrings, which are more eccentric. Once you buy and replace it, you will find that the chain is suddenly tightened and loosened, and the consequences are unpredictable.
(4) Frequently check the matching clearance between the rear wheel fork buffer rubber sleeve and the fork and the fork shaft, because the lateral clearance between the rear wheel fork and the frame is required to be rigorous, and the vertical movement is flexible, only in this way can the rear wheel be guaranteed The fork and the frame can be integrated without affecting the shock absorption effect of the rear shock absorber. The connection between the rear wheel fork and the frame is realized through the wheel fork shaft, and is equipped with a buffer rubber sleeve. Since the quality of the current domestic buffer rubber sleeve products is not very stable, it is particularly prone to looseness. Once the joint is loose, the rear wheel of the motorcycle will shift under the restraint of the chain when the motorcycle starts or accelerates. The magnitude of the displacement is determined by the degree of damage to the cushion rubber sleeve. At the same time, the rear wheel has an obvious shaking feeling when accelerating and decelerating. This is also one of the important reasons for the damage of the chain gear plate. More inspection and attention should be paid.
(5) Clean the chain and gear plate regularly, add grease in time, add rain, snow and muddy roads, and strengthen the maintenance of the chain and gear plate. Only in this way can the service life of the chain gear plate be prolonged.
