To disassemble and assemble the Teana V6 generator, you must first remove the generator belt, then remove the generator mounting screws.
1. Remove the drive belt.
2. Loosen the fixing screw. The details are shown in the figure below:
3. Remove the generator by shaking it.
4. Use mounting screws to secure the new generator.
5. After fixing, install the drive belt and you're done.
Operating Procedures:
1. Before starting, check whether there is sufficient oil in the fuel tank and whether there is oil leaking in each oil pipe. and the seal; Is the amount of water in the cooling system sufficient, clean and leak-free? Is the fan belt tight enough? Check that the transmission parts of the internal combustion engine and generator mustmust be reliably connected, that the output line wires must be well insulated, and that all instruments must be complete and efficient.
2. After starting, it should run at low speed for 3-5 minutes. The operation can only be started after the oil temperature and pressure are normal. There should be no abnormal noise when the generator accelerates, the slip ring and commutator brushes should be in good contact, and there should be no jumps or sparks. After the operation is stable and the frequency and voltage reach the rated values, power can be supplied externally.
3. When abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting.
4. The power factor ofgenerator must not exceed 0.95 in late phase (lag). The variation range of the frequency value should not exceed 0.5 Hz.
5. Before stopping, you must first turn off the main switches of each power branch, gradually reduce the load, then turn off the main power switch of the generator and return the excitation rheostat to the maximum resistance position to reduce the voltage to the minimum value, then turn off the excitation switch and the neutral point grounding switch, and finally stop the operation of the internal combustion engine.

Why does the Saturn car belt make an abnormal noise?
The engine does not have enough cylinders.
When the engine runs out of cylinders, problems such as loud engine noise, low revsunstable lens and abnormal body vibration will occur. In this case, check the condition of the cylinder and the working condition of the spark plug. When the engine is running, the piston skirt collides with the cylinder wall, producing a clear "dang-dang" sound, which is usually more obvious at idle or low speeds.
Can the car be idle charged on site?
What should I do if the car belt makes an abnormal noise?
A way to judge the abnormal noise of the engine belt
Step 1: If there is an abnormal noise in the engine compartment of the car, it means that the belt is usually loose or poor quality, so check the motor belt first. If there are many belts in the car, we cannot know which one is defective. You can start the car and pour water on the belt. If the abnormal noise disappears, there is a problemwith the belt. We can see if it is loose or poor quality.
Abnormal noise coming from the engine belt. Water is poured in to increase its viscosity, which actually increases the viscosity of the belt. But once the water dries, the belt will return to its original shape. This is the principle of belt watering.
Step 2: We can also judge which belt has problem by listening to the sound. If there is a problem with the steering wheel, there may be a problem with the steering pump belt. If there is an abnormal noise when the car starts cold, there may be a problem with the engine belt, and we can check it step by step.
A method for determining and solving the problem of abnormal engine belt noise
1. The engine belt squeals.
This is because the joining surface of the belt and pulley is relatively smooth. This usually happens whenthat the engine speed changes quickly. Sometimes the load on belt-driven accessories increases, which can also cause the belt to idle.
A squeaky belt usually means that the coefficient of friction on the belt surface has been significantly reduced and the belt is excessively worn. If there is noise when the vehicle is loaded, you may want to observe one of the drive belts and notice that the resistance or elasticity of the automatic belt tensioner or tension wheel of the belt will increase abnormally.
Most automatic belt tensioners have a set of belt wear length indicators on the slider located between the bottom of the belt tensioner and the tensioner arm. The mark consists of a pointer and two or three marks indicating the working range of the belt tensioner. If the pointer is atoutside of this range, the belt may be overstretched and need to be replaced. On cars without an automatic belt tensioner, use a standard belt tensioner gauge and measure halfway between the two pulleys. If it differs from the standard value, it is better to replace the belt.
2. The motor belt makes a long-term squealing or high-pitched noise
Although the surface of the pulley is stained with sand and other dirt or the worn belt is installed upside down, the The belt will make a long-term high-pitched noise or squeal, but this is usually caused by poorly assembled auxiliary devices.
If the noise occurs in a new car that has not been driven for a long time, it may be caused by poor quality of the original equipment. Check the visual elements that you think could be causing the malfunction. If the above noise occurs in an old car, yous then need to consider whether you need to completely replace some of the associated accessories of its auxiliary drive unit. Carefully examine accessories that could have been delicately replaced (such as generators, auxiliary steering pumps, etc.). ) and check if their mounting brackets are secure, which can also cause misalignment of the pulley assembly.
Dust or sand between the pulleys and pulleys can also cause loud noises, so if the car is used in a dirty environment, check the surfaces of all pulleys for dust.
Take the example of the timing belt. It must be adjusted immediately after installation. This is why the direction of rotation of the timing belt must be marked. If the timing belt was installed backwards during other maintenance, you will hear a high-pitched squealing soundwhen the belt is running.
Try reversing the direction of installation of the belt to see if the fault disappears.
3. The motor belt is making a whistling, clicking, roaring or chirping sound.
A persistent whistling or clicking sound that increases with engine speed usually means that the auxiliary rotating mechanism bearings are deprived of power. oil.
Using a stethoscope, we can hear these noises more. Next, remove the drive belt and turn the suspected defective part by hand. If it is difficult to turn or the noise is rough or crackling, do not hesitate to replace the bearings or corresponding parts. However, it should be noted that whenever you replace parts of the auxiliary transmission accessories, remember to replace the belt elastic pulley and automatic elastic device.
As engine speed increases, the ruContinuous rolling gradually turns into a whining sound, indicating that the corresponding bearing will soon fail.
4. Engine Belt Rumble
Rumble is a typical noise caused by belt vibration, especially when the auxiliary mechanism transmission system is running and when the engine reaches a certain speed, the noise will increase considerably. The cause of this failure is usually that the drive belt is too loose, too tight, or the belt tensioner and elastic pulley are damaged.
If the car engine belt is abnormal during the warranty period, it is recommended to contact the 4S store as soon as possible to negotiate repairs. Once the warranty expires, you may have to pay for repairs at your own expense. Engine belts are automotive wear products and must be replaced regularly.lierly. Replacing the engine belt on some models is very complicated. It is better for car owners to go to a repair shop or 4S workshop for replacement.
The car can be charged after 20 minutes of starting.
Charging conditions:
Starting the car on the spot for 20 minutes can charge the car battery, if it is just to help replenish the car battery, idling is enough. When the car battery is not powered, the engine speed can be maintained at 1500 rpm for 20 minutes, which can be used by the starter to start the engine once, and if maintained for 30 minutes, it can be started once the next time. day. ?
Precautions for car batteries:
If the car is not used for a long time, the battery will lose powerpower because the battery itself discharges automatically. Features: If the car is not used for a long time, it is recommended that the car owner remove the negative terminal of the battery. This can prevent battery loss and at the same time extend battery life. If the car battery is low on power, you can choose to charge it using a power cord. Use a power cord to connect the positive and negative poles of the battery. It should be noted that you do not need to complete the connection. in the wrong direction, otherwise it may burn the battery. In addition, car owners are recommended to remember to turn off the car's electrical equipment before turning off the car during daily car use, especially the car headlights, driving recorders, etc. car battery power.
Precautions for idling in place:
Idling for a long time will cause higher fuel consumption than normal driving and it is easy to produce carbon deposits. When charging in place while idling, you should try to turn off high-power electrical appliances in the car. If you turn on high-power electrical equipment such as air conditioners, high beams and car audio while charging, the maximum power of. generator power will be exceeded, a battery that doesn't have much power in the first place will be overdrawn, causing permanent damage to the battery.
What is spot idling:
Car spot idling refers to a working condition in which the engine is idling and the gear is in neutral. , which is what we call “The work is done effortlessly”, the fuel is consumed on the spot and the car does not move.
Why idling in place will charge the car:
First, let's talk about why the car can be loaded in slow motion. The car's generator is driven from the engine's crankshaft via a belt, which is a "speed-increasing transmission."
When we repair cars, if you observe carefully, you will find that the crankshaft pulley of the engine is much larger than the generator pulley, and the speed of the generator is generally about 2.5 times the engine speed. the engine idles at a speed of 800 rpm, the generator speed is usually around 2000 rpm. For example, for some small displacement engines, if you turn on the headlights when the engine is idling, not only will the headlights be very dim, but the engine will shake violently. This is whatwhich many experienced drivers call “the power take-off”. What does that mean? This means that the headlights are drawing too much power, causing the ignition system to have insufficient power and poor ignition to the engine, which will naturally cause it to vibrate. However, some "smart" drivers discovered that as long as they pressed the accelerator a little, the engine became much more stable and the headlights became brighter. This is mainly because the speed of the generator increases, producing more power and current. After keeping the engine running, if there is power left, the battery can be charged.
From here you will also find that idling the engine can actually charge the battery.
Solution in case of significant power loss:
1. First make sure the auxiliary battery is12 V and the negative terminal is connected to ground. Of course, we also need to turn off all unnecessary lights and accessories to avoid electrical accidents.
2. Then follow the sequence shown in the figure below to connect the jumper cables. Make sure not to reverse the positive and negative poles of the cable, otherwise sparks will fly when you connect them. We also need to wrap the cables and battery well (full contact) to avoid sparking when connecting.
3. Start the engine of the auxiliary battery vehicle and run the engine at medium speed. Then start the engine of the vehicle with a discharged battery.
4. Finally, simply unplug the cables in exactly reverse order.
