1. Motorcycles within the warranty period, principlesYou can go to any specialty store of the brand for free repair (of course, the repaired faults are also covered by the warranty, and those that are not covered by the warranty cannot be repaired free of charge).
2. Motorcycle specialty stores can help you order or motorcycle accessories stores can also get it. Generally, they sell bulk parts, because overhaul is to change the piston or cylinder liner, and rarely replace the assembly.
3. Except for motorcycles and wheeled self-driving machinery) If the motor vehicle safety technical inspection pass mark is issued for the first time this year, the Motor Vehicle Delayed Scrapping Approval Form also needs to be submitted. Now the annual inspection of motorcycles needs to be tested online. The inspection fee is between 40 and 60 yuan, the traffic insurance of 120 yuan, and the labor cost of 10 yuan.
Check whether the quality of the newly replaced cylinder, that is, the quality of the cylinder block, piston and piston ring is qualified, whether the model is correct, whether there are problems in installation and debugging, etc., whether the gas distribution timing is correct, etc.
Change the cylinder: If the cylinder is seriously pulled and the processable margin of the cylinder wall is too poor, and the suitable plugs and rings cannot be selected, a complete set of cylinders, plugs and rings are generally selected to replace them.
Check whether the gas timing is correct. If the gas timing is wrong, it will affect the start-up and acceleration performance. However, if it is a top-bar engine, replacing the above parts will generally not affect the timing of the gas.
1. The simplest repair method for motorcycle oil burning: change the piston ring and improve the cylinder assembly. Replacing the piston ring. If it is just an oil-burning failure caused by normal wear, and the cylinder block is not pulled, the fault can be completely eliminated by replacing the piston ring. If you choose a high-quality piston ring, the repair effect is also better.
2. Motorcycle burning engine oilThe simplest solutions include motorcycles paying attention to the cleanliness of the fuel oil line, regular maintenance of motorcycles, and the use of high-quality engine oil for motorcycles, etc. Motorcycles should pay attention to the cleanliness of the fuel oil route. The use of high-quality fuel additives can keep the fuel oil route clean, which is the key to preventing oil burning.
3. If you find the phenomenon of burning oil, the handling method is: go to the repair shop to replace the aging oil seal and rubber ring. Go to the repair shop to replace the cylinder block and piston. When the piston is worn too much or the piston ring loses its elasticity after long-term use, the seal is not tight, and bringing too much oil into the combustion chamber to participate in combustion will also form burning oil.
4. Replace the cylinder block and piston, because the wear of these two parts for a long time will cause oil leakage. Just replace the new rubber ring. If the rubber ring is used for too long, the oil will be loosely sealed.Replacing the oil filter, the blockage of the oil filter will lead to an increase in oil consumption.
5. The solution is as follows: First, check whether the oil level is too high, because if the oil level is too high, it is easy to cause the oil to rise. When checking the oil surface, it should not be checked after the engine has just stopped. It should be checked after 10 minutes of shutdown. If the oil level is too high, the excess oil should be released in time.
6. Repair method for slight oil burning of motorcycles: choose the appropriate oil according to the actual situation; choose gasoline with good oil price; maintain good driving habits.
First of all, if you want to repair the cylinder of Zongshen three-wheeled motorcycle, you need to replace the damaged parts such as cylinder block, piston and piston ring. Secondly, check whether the failure of the adhesive cylinder is serious, and the crankshaft connecting rod and bearing need to be replaced. Finally, after the replacement, it will be tested to ensure safety.
It is solved by replacing the sleeve cylinder (cylinder, piston ring, piston) and engine oil.
Water in the brake system causes the blisters of the brake main cylinder to expand, which needs to be replaced immediately.
The rear fender is the one behind the fuel tank, without corrosion and rust. If there is no major problem with these two parts, it can be considered for repair. In fact, the power of the 110 is very cheap now, and you can get a brand-new one with a thousand yuan. For maintenance, as long as the crankshaft connecting rod is not dead, the cylinder is burned too serious, the gear teeth are worn and broken, so on.
You try according to my method. First of all, replace the original sleeve cylinder, which should be replaced together with the conduit oil seal and air filter. To change the oil, the oil must be a big brand oil above sj level, and pay attention to add only 0.8 liters. In the future, change the oil and maintain the air filter every 1,500 kilometers. Change the oil twice and replace the air filter. If you have any other questions, you can continue to ask me.
Generally, if the valve is not closed, you only need to grind the valve, the valve seat or replace the new valve. If the valve seat is also seriously worn, the general car does not have much maintenance value. Moreover, the cylinder head of this kind of engine is not expensive, and now it is rarely needed to ringed the valve seat.
1. The cost of repairing pedal motorcycle head faults, from simple debugging to replacing parts, ranges from tens of yuan to hundreds of yuan.
2. More than a thousand to about 10,000 yuan. In terms of expenses, the new engine accounts for about 15% of the total price of the vehicle. That is to say, your vehicle costs 200,000 yuan, so it will cost about 30,000 yuan to replace a new set of engine. And if you choose a major repair, it must be cheaper than this price.
3. Pedal motorcycles burn engine oil, generally need to replace the cylinder block, piston, piston ring, valve oil seal and cylinder pad, etc. If it is an ordinary domestic brand pedal, the general maintenance price is about 200 yuan. If it is some expensive cars, special models or high-end models of joint venture brands, maintenance The price is even more expensive.
4. According to the severity. The slightest replacement of the middle cylinder, piston, piston ring, piston pin, valve oil seal (cylinder sleeve). 200-300 slightly serious sleeve cylinder intake and exhaust valve camshaft rocker arm 400-500 the most serious sleeve cylinder intake and exhaust valve camshaft rocker arm oil pump crankshaft.
1. If there is a problem with the motorcycle, it needs to be repaired. If you have strong hands-on ability, you can repair it by yourself. However, if there is a problem with the engine, it is generally more troublesome. Next, I will introduce a few issues that should pay attention to when disassembling the motorcycle engine.
2. It's not easy to repair.The bent beam motorcycle engine is not compressed, which usually means that the fuel in the cylinder cannot burn normally to produce energy. Repair involves many details, such as piston rings, valve gaps, etc. If operated improperly, it may cause bigger problems.
3. The cylinder of the bent beam motorcycle has risen, and only the cylinder block, piston, piston ring and other parts can be replaced, and the crankshaft connecting rod needs to be replaced in serious cases. In addition, it is also necessary to check and exclude the reasons for the rise of the cylinder, such as whether the oil is not good or lack of oil, whether the oil pump is damaged or the oil filter element, filter or oil channel is blocked, so as to avoid damage after replacing the new part.
4. You can unplug the starter motor from the right side. If you need to further disassemble the starter motor, you need to remove the fixing screw of the starter motor shell, and then you can separate the motor. Disassembly and maintenance of the starting motor require certain maintenance experience and tools. It is best to go to the after-sales service or motorcycle repair shop for repair.
5. After nearly ten years of actual maintenance work, I summarize the matters that should be paid attention to in the overhaul of motorcycle engines as follows, and I hope to encourage you. The operating environment should be dustproof and windproof, and the operation should be standardized. Some motorcycle repair shops overhaul engines are operated outdoors. No matter how big the wind and dust is, they only care about replacing parts.
