Where to add the front shock absorber oil of the motorcycle, and how much to add to the oil change o

Add the front shock absorber oil to the motorcycle, as long as the shock absorber is removed.

The center rod and oil seal, according to your own habits, add the amount of oil, you can determine the height of shock absorption and cushioning strength. Hydraulic shock absorber is the most commonly used shock absorber for motorcycles, and its working principle is briefly introduced.

1. Hydraulic damping rear shock absorber.

The structure of the hydraulic shock absorber is basically similar to that of the suction pump, except that the upper end of the steel body of the hydraulic shock absorber is closed, and the valve has a small hole. When the rear wheel encounters a raised road surface and is impacted, the cylinder barrel moves upwards and the piston moves relatively downward in the inner cylinder barrel. At this time, the piston valve is flushed upward, and the oil on the lower side of the piston in the inner cylinder cavity flows to the upper side of the piston without any resistance.

At the same time, this part of the oil also flows into the oil chamber between the inner and outer cylinders through the small hole in the bottom valve. In this way, the impact load on the vehicle on the uneven road surface is effectively attenuated. When the wheel falls over the raised ground, the cylinder barrel will also move downward, and the piston will move upwards relative to the cylinder barrel.

When the piston moves upwards, the oil rushes through the valve at the bottom and flows to the inner cylinder barrel, while the oil on the upper side of the piston of the inner cylinder barrel flows down through the small hole in the piston valve. At this time, when the oil flows through the small hole, it will be subjected to great resistance, which produces a good damping effect and plays the purpose of shock absorption.

2. Telescopic tube fork hydraulic shock absorber.

The telescopic fork is connected to the front wheel and frame, which not only plays the role of a part of the skeleton support, but also plays the role of a shock absorber. As the shank and casing retract each other, the oil in the fork flows through a small hole set in the next door. When the shank is compressed, the oil in chamber B is pressurized and flows to chamber C through a small hole in the shank as the shank moves (as shown in Figure 1).

At the same time, it flows to chamber A through a free valve. As the oil flows, the resistance attenuates the compressive force. When the compression stroke is almost at its limit, a tapered oil seal at the end of the shank is inserted, thus closing the oil access to chamber B.

At this point, the oil pressure in the B chamber rises sharply, leaving it in a closed state, which limits the travel of the shank and effectively prevents instantaneous mechanical collisions between the moving parts on the fork.

When the shank is extended (i.e., **), the oil in chamber A flows to chamber C through a small hole located in the upper part of the fork piston (near the piston ring). At this point, the resistance to the flow of the oil attenuates the tensile force. When the extension stroke is almost at its limit, the elongation of the ** spring absorbs the vibration energy, and in the process, the oil is replenished into the B chamber through a small hole in the lower part of the fork piston, ready for the next job.

2) Add 10ml to one syringe

How much to add shock absorber oil to the front of the motorcycle: the oil level of the new spring is 5 7 cm lower.

You use a needle to add 10ml to try it "Pay attention to the use of a large ladder when refueling, press it up behind the branch of the big ladder, and then the front shock absorption is deep to the highest point to see if the top screw rubber ring is broken, and it is better to die if it is intact" If you are still weak, you are in +10ml

If it is a general 125 or 150 straddle bike, the oil volume of the front shock absorber is about 120-150 ml, if it is a larger prince or street sports car, the oil volume can reach about 170 ml, and if it is a curved beam or scooter, it is generally below 100 ml.

The hydraulic shock absorber of the motorcycle should be checked frequently for oil leakage, check whether the shock absorber oil is sufficient, and replace the shock absorber oil regularly, generally once a year.

Before changing the shock absorber oil, remove the steering handle, front wheel, fender, brake caliper in order, loosen the fixing screws on the upper plate and the direction post, and then turn the handle back and forth, and then slowly pull out the handle.

Introduction:

For motorcycles equipped with fork dust covers, the dust cover and fork cover bolts should be removed first, and then the fork cover bolts should be prevented from popping out under the action of the spring to cause accidents, and attention should be paid to them. If you encounter an air-pressurized shock absorber, you should press and hold the valve core with your hand to discharge the air inside before loosening the bolts, and then remove the spring pad, spring guide, fork spring, and move the handle in order.

Finally, pour out the shock absorber oil in the fork, add new shock absorber oil according to the regulations, and then slowly move the handle up and down several times to remove the air mixed in the shock absorber, and finally install all the parts in order.

It depends on what kind of model it is, if it is a general 125 or 150 straddle bike, the oil content of the front shock absorber is about 120 150 ml, if it is a larger prince or street sports car, the oil volume can reach about 170 ml, if it is a bend beam or scooter, it is generally below 100 ml.

There are many kinds of motorcycles of 125, and the front shock absorbers they use are not the same, both relatively long and thicker, and also shorter and thinner, due to the different model sizes of the front shock absorbers, so the amount of shock absorber oil in these front shock absorbers is not the same, how much to add depends on the specific situation, and the maintenance parameters of these front shock absorbers are required, and the shock absorber oil can be just applicable according to that standard.

The common 125 straddle motorcycles, their front shock absorber oil volume is about 130 ml-180 ml, and some front shock absorbers are thicker and longer, such as some cruising prince 125 motorcycles, their front shock absorber oil volume can reach more than 300 ml, the difference can be about doubled. If it is a 125 motorcycle of the curved beam type and the pedal Xiao leather plate type, their front shock absorber is relatively short and thinner, so the shock absorption oil is less, generally only.

Seventy or eighty milliliters.

If the model is uncertain, and the maintenance parameters of the front shock absorber of the motorcycle can not be found, you can also refuel according to the following method. After removing the screws on the upper cover of the front shock absorber, leave the spring of the shock absorber in the shock absorber, then press the shock absorber to the end, then add the shock absorber oil to the full, pull the shock absorber up and install the upper cover, and then press the shock absorber back to see how the effect is. If you feel okay, put the shock absorber on the car to try it, and then screen the test results to decide whether to adjust the shock absorber oil volume.

There are many kinds of 125 motorcycles selling Soche, and the front shock absorber used by it is different, and the amount of oil in the shock absorber is not the same, so it depends on the specific model. In general, the common 125 straddle motorcycle, most of the shock absorber oil in the front shock absorber is more than 100 ml, if it is a 125 bend beam or scooter, their front shock absorber oil is only a few tens of ml. There is another method, although it is not very accurate, but you can also apply for the exam, remove the upper cover of the front shock absorber and press it to the end, and then add the front shock absorber oil to the full, so that the oil volume is enough, and then pull the front shock absorber up, and install the shock absorber cover.

1. Remove the shock absorber, unscrew the screw at the upper end, take out the spring inside, and then press the shock absorber to the end and fill up the hydraulic oil.

The oil level of the general old shock absorber is the most standard! If it still doesn't work, then replace the spring, the new spring oil level is 5 7 cm lower.

2. Briefly introduce the characteristics of the shock absorbing pad for your reference.

Wide vibration isolation spectrum: excellent vibration isolation effect for low, medium and high frequency noise.

Light weight: The areal density of the product is only 1000g m, and the load on the floor slab is small.

Easy to apply: It can be cut into the required size and overlapped to obtain different degrees of vibration isolation effect.

Waterproof and mildew-proof: The outer layer is waterproof, which has good waterproof and mildew-proof performance.

There are many types of 125 motorcycles, and they have shock absorbers.

Different, the shock absorbing oil is also different, depending on the specific model.

Generally, the shock absorbing oil of the straddle 125 ranges from more than 100 milliliters to more than 300 milliliters, while the front shock absorbing oil of the bending beam and pedal 125 is only a few tens of milliliters. If you don't have a specific model to argue about the key, you can also compress the shock absorber to the end, then fill up the oil and pull it up, and install the upper cover to try, so that the softness and hardness are basically moderate.

Extended information: The shock absorber is composed of a shock absorber, a lower spring pad, a dust jacket, a spring, a shock absorber pad, an upper spring pad, a spring seat, a bearing, a top rubber, and a nut.

The shock absorber uses fluid to convert the elastic energy of the spring into heat energy to make the vehicle movement convergence the most rational, so as to eliminate the vibration brought by the road surface and improve driving stability, and give the driver a sense of comfort and stability.

The shock absorber assembly uses fluid to convert the elastic energy of the spring into heat energy, so as to maximize the convergence of vehicle movement, thereby eliminating the vibration caused by the road surface, improving driving stability, and giving the driver a sense of comfort and stability.

2) Add 10ml to one syringe

How much to add shock absorber oil to the front of the motorcycle: the oil level of the new spring is 5 7 cm lower.

Add hydraulic oil to the front shock absorber of the motorcycle, unscrew the big screw at the top of the front shock absorber of the motorcycle, and the specific operation steps are as follows:

1. Unscrew the big screw on the top of the front shock absorber of the motorcycle.

2. The screws are removed.

3. Use a screwdriver to pry out the spring inside the shock absorber.

4. Take out the spring.

5. Add 100ml of oil to the shock absorber.

6. Install the spring back.

7. Tighten the big screw at the top of the shock absorber and the operation is completed.

There are many kinds of motorcycles, different brands and models of motorcycles, front shock absorbers.

The amount of fuel is also different, so it depends on the specific situation, the general common small displacement straddle motorcycle, the former guess rough friend shock absorber oil volume is more than 100 ml each, bend beam and scooter.

of only a few tens of milliliters. If the original shock absorber is not leaking, then it can also be a little less than the stool socks that are released, and it is best to find the maintenance parameters of the car and add them according to the standard. In addition, you can also press the shock absorber to the end when you don't install the cover, put in the spring and add oil to it, add it to the inner tube when the oil is full, and then load it to try it, and then decide the increase or decrease of the oil amount according to the feeling of the shock absorber.

The general straddle motorcycle, depending on the model, the oil volume of the front shock absorber is only about 120 180 ml each, and adding 300 ml to each is too much, and it will feel very hard. Due to the short shock absorber, the scooter also has less amount of shock oil, only about 80 ml each.

If you feel that the shock absorber is too soft, you can also open the upper cover of the shock absorber and press it to the end (the spring remains in the shock absorber), then add the shock absorber oil to the full, and then pull up the shock absorber and install the upper cover screws, no need to exhaust air.

When changing the shock absorber oil, you can remove the steering handle, front wheel, mud plate, and brake caliper in order, loosen the fixing screws of the upper plate, and the fixing screws of the direction column, rotate the shank back and forth from left to right, and slowly pull out the shank. For motorcycles fitted with a front* dust guard, the dust cover and front cover bolts should be removed first (the front * cover bolts may pop out under the action of the spring, so attention should be taken). If it is an air-pressurized type, the valve core should be pressed to expel the air before loosening the bolts.

Remove the spring pads in order

Putty powder equipment spring guide tube, front * spring, move the shank tube, pour out the shock absorber oil in the front * . Then inject the recommended front* shock absorber oil according to the specified oil volume, and then slowly twitch the shank.

Two or three times to remove the mixed air, and finally install it in order.

Explain the method of filling the front shock absorber oil of the motorcycle.

Hello, the front shock absorber, should add a special shock absorber oil, shock absorber oil is compressible oil, will increase the cushioning performance of the front shock absorber, shock absorber oil density is small, can be properly compressed, the density of hydraulic oil is not compressible, so absolutely can not add hydraulic oil, shock absorber oil ten yuan a barrel, relatively large motorcycle repair shops have **,

Engine oil can be used, hydraulic oil can also be used, this position is not very demanding

The shock absorbing oil does not need to be changed, nor can it be changed.
