How to replace the old Beverly generator belt?

Second, the parts used: belts, belt tensioner accessories.

3. Tools used: flashlight, screwdriver, pry bar.

Fourth, the operation steps:

01.Turn off the engine and let it cool down, open the hood of the engine to find the generator belt on the front of the engine.

02.Press the belt between the pulleys to check its relaxation, if you press more than 1 2 inches, the belt is loose, the loose belt will affect the performance of the generator and even damage the belt.

03.Check the generator belt for oil or grease contamination, flip the belt over to check for cracks, missing rubber blocks, and slippage in the inner layer.

04.Loosen the adjustment bolts of the development motor and adjust the pivot bolts.

05.Move the generator inward to release the belt.

06.Strip the generator belt from the pulley and remove the generator belt.

07.Compare the removed old belt with the new belt, confirm it, and install the new belt.

08.Pull the generator outward until the belt is tight, making sure the generator belt is installed in the proper position.

09.Adjust the pivot bolts in strict accordance with the manufacturer's instructions.

10.Start the engine to verify the repair results, and recheck the tightness of the belt after turning off the engine.

You need to remove the air conditioner belt first.

Timing belts. Low noise, low transmission resistance and low transmission inertia, which can improve the power performance and acceleration performance of the engine, and is easy to replace. But the disadvantage is that it is easy to age, and the failure rate.

High, the cost of use for car owners is relatively high.

1.Engine belts.

The installation requires a certain amount of skill: the crankshaft and the camshaft are aligned.

Ignition mark, hang the belt on the crankshaft wheel, and hang it straight on the camshaft wheel from the opposite side of the tensioner by the way, and then fold the belt into the side of the tensioner, and brace the tensioner tighter.

2.The installation of the engine belt requires a certain amount of technology: the ignition mark of the crankshaft and the camshaft, the belt is hung on the crankshaft wheel, and the belt is hung on the camshaft loss wheel from the opposite side of the tensioner, and then the belt is folded into the side of the tensioner and the tensioner can be tightened.

The tightness of the timing belt is very important, if it is too tight, the tension is too large, it can easily lead to breakage and affect the life of the belt; Therefore, after the timing belt is installed, the tightness needs to be adjusted to the belt pressure to 10mm looseness, which can be flipped 90 degrees. If the belt is pressed less than 10mm, it means that the timing belt is too tight.

3.In addition, if the timing belt is too loose, it is easy to slip, resulting in the configuration timing lag, resulting in the car shaking, refueling weakness, insufficient power, increased fuel consumption, etc., and it is easy to jump teeth when the engine load is large or the power impact is large, which may lead to the top valve, thereby damaging the engine. The use of the belt should be checked regularly to check whether the tightness is appropriate, and if it is too loose or too tight, it should be adjusted in time; In addition, it is also necessary to check whether there are cracks on the surface of the belt, whether the tooth shape is worn, if the wear is serious or cracked, it should be replaced in time to avoid breakage.

Generally speaking, if the generator belt is replaced once every 60,000 kilometers or two years, the belt replacement time on the car is stipulated by the manufacturer, and it is introduced in the maintenance manual of the car. According to the general car maintenance and use standards, the generator belt will be replaced about 60,000-80,000 kilometers, and a small number can be replaced after 80,000-100,000 kilometers.

Inspection, adjustment and replacement of generator belts.

1.Belt inspection.

Check if the belt is damaged or detached. If yes, replace the belt in time.

Check the tightness of the fan belt, see "Belt Mistracking Check" for details.

2.Belt adjustment.

If the generator belt is too loose, it can cause problems with undercharging and engine overheating.

When adjusting the belt tightness of the generator, use the adjusting bolt to move the entire alternator inward or outward to adjust the belt tightness, as shown in Figure 1-6-2. After adjustment, the fixing bolts should be tightened reliably. Note:

Don't tighten the belt too tightly, or it will damage the fan belt and bearings. During operation, care should be taken to avoid the belt being contaminated by grease, otherwise it will cause sliding wear and shorten the service life.

3.Belt replacementWhen there are precursors such as cracks, wear, and peeling on the surface of the belt, or when there is a sliding sound, it means that the belt may break. At this time, the belt should be replaced in time.

When replacing the belt, first loosen the fixing screws of the development motor, move the generator in the direction of the cylinder block, loosen the belt, and then remove the belt. If the belt is still not easy to remove after being released, insert a screwdriver between the pulley and the belt and pull the belt outward while rotating the pulley so that the belt can be removed.

Condition in which the generator belt is too tight and too loose.

Too tight: 1. The belt card is dead, and the rotation needs more power; 2. It will cause the axial load of the motor shaft to be large and easy to fatigue; 3. Endanger the service life of the belt; 4. It is very easy to cause the destruction of the rolling bearing of the automobile engine.

Too loose: 1. Cause deviation and abnormal noise; 2. The belt will be damaged in the early stage, which will endanger the service life of the belt; 3. Cause the automobile engine to charge the battery insufficiently, endangering the service life of the battery; 4. The car may be idle and shaky, not enough driving force, high fuel consumption, and high temperature.

Signs of generator belt replacement.

1. In the case of the generator belt in operation, in the case of outgoing.

This kind of condition is caused by the envy cavity in the car engine belt is too loose, or the assembly part is uncertain, and it is best to check immediately if the slip grinding sound occurs.

2. The generator belt is cracked, cracked and falling off.

This kind of situation is due to the incorrect installation part, uneven bearing force or erosion, or due to the long application time, the automobile engine belt has long been brittle, hard bottom.

3. When the service time of the generator belt is almost 2 years, or when the driving time is 60,000 kilometers.

The service life of the general automobile engine belt is 2 years or 60,000 kilometers, so it must be dismantled and replaced when the required service period is reached. It is certainly not possible to replace it until it is broken, which is very easy to cause risks.

What happens if a generator belt breaks?

If the generator belt breaks while the car is in motion, then the car is likely to lose its driving power all of a sudden. If the distance between the cars is not enough, it is very easy to cause road traffic accidents, and it is better to go to the situation on the highway.

Therefore, in ordinary times, we must always check the automobile engine belt, generator belt, centrifugal water pump belt, compressor belt, engine timing belt and other components on the car, to ensure that the components on the car are basically working under better conditions.

Hello dear! Precursors of generator belt replacement may include the following:1

Abnormal engine noise: After the generator belt is aged or worn, the abnormal engine noise may be eliminated, which is generally caused by the slack or serious wear of the belt. 2.

Low battery voltage: After the generator belt is aged or worn, the generator cannot work normally, and the voltage of the battery will gradually decrease, resulting in difficulty or failure to start the vehicle. 3.

Engine cooling water temperature rises: After the generator belt is aged or worn, it may cause the engine cooling water temperature to rise, because the generator cannot work properly and cannot provide enough power to the vehicle, which will affect the normal operation of the engine. If the above phenomenon occurs, the generator belt should be checked and replaced in time to ensure the normal operation of the generator and the safe driving of the vehicle.

Hello dear, thank you for waiting for the precursors to the generator belt replacement are mainly the following. The first point is that the engine has a branch and obvious abnormal sound after starting, and there will generally be a squeaky sound, the second point is that the vehicle will make a squeaky sound when accelerating or the lack of ears when the air conditioner is turned on, the third point is that when the vehicle turns on the lights, it will make a squeaky sound, and the fourth point is that the vehicle is easy to smell the smell of rubber burnt during the driving process, if the above points appear, it is necessary to consider replacing the belt. <>
