Pay attention to whether the old and new parts can be used.
Compare them one by one and see if you can plug them in.
On the internet, in books, look up the knowledge of motorcycle principle everywhere.
Let's get started!
(1) Put the crankcase on the mounting frame, install the ventilation hose, scrape off the residual glue, remove dust and sundries, clean the crankcase cover, try to close the empty crankcase cover and crankcase, and disassemble the crankcase cover and crankcase again;
(2) Install shift cam, gear shafts II and III, gear and ratchet shaft IV, check whether shafts II and III are in meshing state, check whether the direction of shift camshaft is in place, check the meshing of shaft IV and shaft III, and close and lower the box; Check the engagement of shaft 2 and shaft 3, and the engagement of shaft 3 and shaft 4;
(3) Install 1 1 screws with the box facing upwards; An oil pump with an upward box cover and equipped with a shift lever, a shift camshaft positioning block, a shift limiter, a starting lever return spring, a guide sleeve, an I-axis driving bevel gear, an II-axis driven bevel gear, an outer clutch drum, a gasket, an inner drum (the spring is not disassembled) and a friction plate; Loading ejector pin; Install the clutch cover and needle roller;
(4) Flip 180 degrees with the box facing up; Install neutral indicator; Installing a magnetizing motor; Sprocket (flywheel); Magnetize the motor rotor with the handwheel and check whether the flywheel rotates; Install the piston; Loading cylinder and cylinder pad; Loading cylinder head; Install carburetor; Oil loading pump cover; Install the motor cover; Install the clutch cover.
Question 2: How to assemble the folding bicycle (preferably with pictures)? You can go to the garage and ask the master to install it. Master, don't read the instructions too fast! My giant 20-inch folding bicycle Xiaobai was installed by a mechanic. After paying 20 yuan, I can't ride for a week. Xitang xiaodeng
Question 3: Assembling a bicycle To be honest, you can't assemble a car at this price. Might as well just get in the car. For example, the giant Gong TX660 or Merida Warriors 550, Decathlon 5. 1. Think about it. If you buy parts for assembly, it will definitely be more expensive than the whole vehicle. If you want to assemble, don't install it without a budget of 2000. There is no cost performance.
Question 4: How to assemble the front and rear brakes of children's bicycles depends on what brakes they are.
Question 5: How can bicycles be assembled into electric bicycles (battery cars)? What materials are needed? Five points. Hehe, buy a 36v bicycle-like electric car, and the price is only about1.4000. I can't reform myself. You have to buy motors, controllers, handlebars, power-off brakes, wires, batteries and many other things. What's more, what you bought is the retail price, not the wholesale price. You can't get it without 1600 yuan.
Question 6: How much does it cost to assemble a bicycle? Assembling a car requires style and cost performance. Some small parts of low-end cars, such as cushions, handlebars, pedals and bowl covers, are basically rubbish. What's more, those chains, leggings, bells, kettle racks and side branches you bought for the whole car don't add up to more than 100 yuan. The most important thing is what kind of lock you send. That kind of lock is only a dozen dollars. Son, just give it your head and put it in 3000. 3000 assembling truck can hold 430 sets, XC28 front fork. Much more cost-effective than the whole vehicle. Of course, the 5000 assembled car is better. 590 sets and R7 can be loaded. Actually, 3000 yuan is just a hurdle. As long as it exceeds the level of 3000, you can install it yourself. Don't go to the store and ask. What is the shop doing? They sell cars! Who else will I sell my car to when I install it in the shop? I was blacked out by their club in QQ group because I rode my own assembly car to participate in the activities of local clubs. I'm afraid it will affect their business. If the landlord really wants to assemble the car, I advise you not to assemble it in a hurry. Learn more in post bars and forums. Then I can buy parts online and install them at home. Don't take the burden too seriously. It's actually quite simple. A little more complicated online has video tutorials (for example, of course you have to prepare a set of tools. Anyway, I will often use it when I do other things in the future. Assembly vehicles shall not be assembled in the garage. I don't need to say more about the reason (unless your best friend is an acquaintance there). View original post >>
Question 7: Tools for assembling mountain bikes and how to assemble mountain bikes? Hello, I'm from the bicycle club, and I often watch my friends load cars. I learned something myself.
The assembly car first represents the tools:
Necessary tools: Gong, 5 yuan, a set of effective cards, not bad.
Torx screwdriver, 6 yuan, pliers 13 yuan, wrench 12, Great Wall brand.
I found someone to glue the aluminum out of the tire, and I can find a way to get it myself.
This is used for diversion. This is a switchboard. It is common that the diverter strip is elastic.
Pump, I bought a horse 100 yuan, but I regretted it after buying it. It is made of plastic and doesn't work well. Why don't you go to the grocery store and buy a 10 yuan one?
The above can be purchased at 5 gold shops. Here are some special tools.
Flywheel removal tool, just remove the stuck fly, buy about 30 on Taobao, and it is useless to remove the rotating fly tool. One is that there are few rotating flies now, and the other is that they can be disassembled and installed in the car shop without special tools.
Tools for picking up and unloading intermediate shafts should be able to remove splines and square shafts at the same time. Also known as Lama, Taobao is about 35. In fact, there is an extra round washer.
De-chaining tool, Taobao 25
Other tools are unnecessary and unnecessary. The total cost is about 150, which is quite good.
In addition, I recommend you to watch the video. After all, video is more direct and specific.
Youku/... Ding = 1
This is a video collection I have seen. I hope it helps you.

Question 8: How to assemble the front beam package of mountain bike The beam package of mountain bike is very convenient to install:
Two belts, one fixed to the pipe on the front of the car and the other fixed to the girder, are made of magic buckles, which can be removed and left when you get off the bus, which is absolutely safe.
Mountain bike beam bag has a wide range of uses, which can hold mobile phones and personal items, especially suitable for mountain bikes. Cell phones, wallets and tools can all be put in. The most convenient thing is that there is a small bag with a mobile phone on it, so you don't have to stop to answer the phone anymore. The beam bag of mountain bike is filled with pearl cotton, which effectively reduces the influence of vibration on the items placed inside.
Question 9: Installation of mountain bike disc brakes Since your friend said that your mountain bike can be installed, it means that your hub fork and frame are supported.
Installing disc brake
Tools you need: Just a set of Allen wrenches and t25 ring wrenches.
Let's start with the above picture.
The purpose of the above picture a is to adjust the passive collar (that is, the top one in the above picture). The collar is fired at high temperature, and the most taboo is oil, so don't stick oil stains, otherwise cleaning will be very troublesome. The most commonly used disc brake adjustment is to adjust the passive collar, as shown in the following figure.
Shimano's 3mm inner hexagon is used for adjustment. When the screw rotates in the direction of the super arrow, the gap between the two collar pieces is small.
Tighten the first two tabs and the tabs will stick together.
Next, the disc brake disc will be installed.
Disc brake can be divided into positive and negative sides! The text indicates that the front is facing the outside of the wheel, and the direction indicated by the arrow in the figure is the direction of the wheel movement. Shimano should also install gaskets.
The next step is to install the quick release lever.
Note that the handle of the quick release lever should be placed on this side of the disc brake, the two conical springs on the lever should be placed on both sides of the flower drum, and the two small heads should be above the inner side. Is to put two little heads face to face.
All right, the front wheel is fixed! Now we need to install the brakes! ! !
Fix the two screws and the brake line, but the brake line should not be too tight, which will shorten the line. Now it is necessary to fine-tune the handle system and adjust it to the right position. The longer it is screwed out, the longer the pipe will be, which is equivalent to shortening the brake line, so that the brake will be better used and it will be easier to rub the disc. At the beginning, adjust the fine adjustment to the appropriate position to facilitate the later debugging.
Next, hold the handbrake and see where it is. Give it a gentle pinch, and it will be pinched to the end. The following figure
This means that the distance between the two tabs is too far, so it needs to be adjusted more tightly.
Twist counterclockwise, and pinch the handbrake while twisting. To what extent? For example, if you want the adjusted brakes to have a distance of one centimeter after death, those will now be adjusted to a distance of two.
After the adjustment, I will retreat a little. I feel that it is usually adjusted to about 2 cm, and it is about 1 cm after adjustment. Now roll the brakes. That's why I said I couldn't die. If I die, I can't adjust. Then one hand pinches the brake, causing the collar to bite the brake. Now, start to tighten the two fixing screws. Remember to screw at the same time, that is, one screw turns a quarter turn, the other turns a quarter turn, and the two screws are exchanged until they are screwed to death. Now release the handbrake and look at the distance between the brake pad and the two collar plates. You will find that there is a distance between the active collar plate and the brake pad, while the passive collar plate is closely attached to the brake, which will definitely wear the plate. Now, the inner hexagon adjusting the passive collar plate will turn a little counterclockwise, so that it will not grind. In theory, the passive collar plate is getting closer and closer to the brake pad, but it is very difficult to operate in practice. Generally, the gap should be controlled within 2mm. Such disc brakes are basically adjusted, and the later adjustment and fine-tuning are based on personal preferences. Generally, the front wheel brakes should not be too tight, which is too dangerous.
