The shock absorber oil uses the resistance of oil flow to consume the energy brought by the drive. When the cylinder piston in the shock absorber moves under the action of external force, the oil flows at high speed through the damping channel, and the friction consumption function converts it into heat. Therefore, the shock effect of the motorcycle is weakened until it disappears. In addition, the shock absorber oil also needs to lubricate sliding parts and prolong the service life. Therefore, the motorcycle shock absorber oil must have good rust and abrasion resistance.
Open the suspension top cover to check the entire suspension, observe the operation of the suspension mechanism and the viscosity of the oil
After waiting for the suspension oil in the tube to drain, start removing the oil seal and gasket.
When disassembling the oil seal card spring, you must pay attention to it, and wrap it with something to prevent the card spring from flying away.
After removing the retaining spring, pull the shock-absorbing white rod and the shock barrel firmly, and the shock is successfully disassembled.
Manually sand out some burrs on the spring groove to make the shock absorber run more perfectly.
All parts are installed after regular cleaning and maintenance, because the wiper tongue of the shock absorber oil seal is very delicate. In order to prevent the shock absorber oil seal from being damaged during installation, you must apply a little oil when installing the shock absorber oil seal. Next change the suspension oil, I believe it will give the owner a better driving experience. By the way, a point of knowledge is that the shock absorbing oil has a viscosity. The 5W and 10W labels on the oil bottle are the viscosity of the engine oil. The higher the viscosity, the greater the resistance to the mechanical part. Generally heavy machinery and highway driving are mostly suitable for using 10W shock absorption oil to obtain better curve support performance; small displacement motorcycles, off-road motorcycles are more suitable for riding on bumpy roads, and 5W shock absorption oil is more suitable. Make shock absorption softer and reduce bumps on the road.
After adding new damping oil, reassemble the shock absorber and wait for loading. The shock absorber returned to the motorcycle. The shock absorber is still the original one, but I believe the effect is no longer the same.
(1) Pay attention to the regular cleaning and dust removal of the shock absorber to minimize the cause of oil leakage. In particular, the shock absorber of the structural form similar to the RX125 model has basically exposed working strokes and is in direct contact with dust. very necessary. Practice has proved that dust is an important factor that causes the shock absorber to leak oil quickly.
(2) When the motorcycle is not in use, be sure to pay attention to the oil protection of the working stroke section of the shock absorber to prevent corrosion and rust of the shock absorber.
(3) Check the fastening of the shock absorber before each ride to ensure driving safety. At the same time, you should also observe the oil leakage of the shock absorber to determine whether it needs to be disassembled or repaired to ensure that the shock absorber is always in normal working condition.
