Remove the positive pole of the battery, loosen the tensioner wheel or generator adjusting screw, and remove the belt to disassemble the generator.

Car generatorsDisassembly and assembly need to remove the generator belt first, and then remove the generator fixing screw, and the generator can be removed1. Remove the generator drive belt.

2. Loosen the fixing screws of the development motor.

3. There is another identical one below.

4. Remove the generator when it shakes.

5. Use fixing screws to fix the new generator.

6. After fixing, install the transmission belt and it is completed.

Precautions. Alternators are widely used in automobiles, and the following points should be paid attention to when using them:

1. Clean the dirt and dust on the surface of the generator frequently, and keep it clean and well ventilated. Envy Ridge.

2. Always check the fastening of the fasteners related to the generator, and tighten the screws of each part in time.

3. The tension of the transmission belt should be appropriate. Too loose, easy to slip and cause insufficient power generation; Too tight, easy to damage the belt and generator bearings.

4. When installing the battery, do not install the wrong one, usually install the positive wire first, not the iron wire, otherwise it is easy to burn out the diode.

5. Adopt integrated circuits.

When the regulator is not running, the ignition should be turned off immediately.

6. It is never allowed to use the "scraping" method to test whether to generate electricity.

7. When the generator fails to generate electricity, it should be eliminated in time, otherwise it will cause more serious failures.

Remove the dust cover first; Dismantle three more heart-piercing wires; Next, remove the back cover screws; Take the back cover off with the stator; Simply remove the front cover.

The order of installation and disassembly is reversed.

Electricity is one of the most important sources of energy in modern society. The generator is a mechanical device that converts other forms of energy into electrical energy, which is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or atomic nucleus fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology, and daily life.

1、Remove the generator drive belt. The specific method is shown in the following figure:

2. Loosen the fixing screws of the development motor. The specific method is shown in the following figure:

3. There is another identical one below. The specific method is shown in the following figure:

4. Remove the generator when shaking, the specific method is shown in the figure below

5. Use fixing screws to fix the new generator.

6. After fixing, install the transmission belt and it is completed.

The generator is divided into two ,,, internal adjustment and external adjustment,,, internal adjustment has a regulator with carbon, it is necessary to disassemble the regulator first,,, this is a generator, this kind of regulator must be dismantled first, and a few long screws around the perimeter are removed in the continuation, hit with a hammer, and there is a brushless generator,,, which is directly dismantled,,, and the external adjustment is the same, directly dismantled.

1. Remove from the engine assembly, remove the relevant covers, pipelines, etc., and then loosen the tensioner or generator installation screws and circuit connections, 2. Disassemble the generator, the back cover - regulator - rectifier diode group (some should be welded down with an electric soldering iron) - rear shell - front pulley (as needed) - front housing - rotor bearing, Jinzhou Baihui replied.

1. Disconnect the battery cable.

2. Find the Orange Stream Generator on the vehicle.

3. Use the snake belt tool to loosen the belt, and then remove it from the alternator's Tanhuai pulley.

When disassembling the generator negative cable, the ignition switch should be in the "off" position. Prevent damage to the ECU and electrical equipment by the electromotive force generated by the grounding of the generator wire. 2) When disassembling the generator transmission belt, the hands of the staff should be clean, and it is strictly forbidden to stick grease and oil to the transmission belt.

3) The generator is very closely matched with the support frame. After removing the generator bolts, the motor can be loosened with a wooden crowbar, which makes it easier to remove the generator. 4) The tightening torque of the generator fixing bolt should meet the specified requirements.

Precautions during generator replacement; Before disassembling and assembling the generator, check and protect the vehicle, turn off the battery power, avoid abnormal ignition, pay attention to the disassembly and assembly sequence, prepare special tools and transmission belts, etc. When installing the generator, the screws must be tightened according to the specified torque, the connection must be firm and reliable, and the engine is the heart of the car. Whereas, an engine is a machine made up of many structures and systems.

It can be said to be very complicated. There will inevitably be times when repairs are needed. Different types of engines have different structures.

There are also different precautions when it comes to maintenance. Next, let's take a look at how to disassemble, repair, and install the engine. We're going to make cars to use.

Know the age of the car, mileage, damaged parts, fuel consumption, etc. And check if the appearance and accessories of the engine are complete? Such as cylinder block, cylinder head, water pump fuel system, etc.

Check for oil leakage or abnormal noise, and start the engine. Also check the cylinder compression pressure. Cylinder pressure affects engine power.

The degree of wear of the cylinder piston can be judged by inspection. Then it is necessary to determine the engine model so that it can be correctly matched with the tools used in the repair. Before disassembling the engine, remove the battery to avoid fire.

During disassembly, they should be discharged sequentially. For reinstallation. When removing the vacuum tube, the middle of the hose should not be pulled.

And pay attention to mark the connecting end of the hose. Avoid installation errors. The engine must be disassembled after cooling to prevent deformation due to excessive temperature during disassembly.

and use professional tools. Be sure to tighten the bolts when overhauling. The tightness of the pump fan housing should meet the technical requirements.

If it is too tight, it will not only break easily, but also shorten the service life of the belt.

In addition, excessive tension can cause deformation of the generator shaft and pump shaft. Generally, the normal belt device is 10-15 mm, and when installing the crankshaft and connecting rod shaft, sufficient lubrication must be maintained, otherwise the shaft will be stressed when the engine rotates.

When installing the bolts, first use a cleaning tool to ensure that the screw holes are clean and free of dirt or water. When installing valve springs, it should be noted that the direction of the springs can be pre-marked. If you forget about the usual situation, the place with high spring density is facing downward.

If the engine temperature is relatively high, never blindly disassemble the thermostat. The coolant does not regulate the cooling intensity. It is difficult to guarantee that the engine will work at the right temperature.

Moreover, the engine works at low temperatures, which will cause the engine power to decrease, fuel consumption to increase, and wear to accelerate. The correct way to do this is to check the rest of the cooling system. Instead of removing the thermostat.

The problem that needs to be paid attention to when replacing the car engine is that we must pay attention to the process of engine installation, and we must also pay attention to whether the installation of the engine is correct, and we must also pay attention to protect our body when installing the engine, and also pay attention to not rubbing the vehicle when installing, which are all problems that need to be paid attention to when installing the engine.

Pay attention to the brand of the engine, but also pay attention to the quality of the engine, but also pay attention to the method of replacement, at the same time pay attention to the installed parts, but also pay attention to the installation of the engine, and so on.

It is necessary to pay attention to the circuit before the disassembly, as well as the connection situation, such as some screw mouths must be screwed up, and pay attention to the way of connection to prevent it from being unusable after disassembly.
