Follow whether changing the flywheel ring gear and starter has an impact on the vehicle

Repair of flywheel ring gears.

The collision between the ring gear and the starter when starting the engine, or the poor meshing of the two gears, is easy to cause wear and damage to the teeth.

Ring gear teeth are usually worn on one side. The ring gear can be turned over. The disassembly and assembly of the ring gear should be heated and the flywheel should have an interference of 8mm.

If the individual teeth are damaged, they can be reused after grinding with a stone stone.

There is serious wear on both sides of the ring gear or tooth damage, and when the replacement repair is not available, it can be repaired by surfacing welding.

Restoration of the flywheel working surface.

The flywheel face is worn or grooved. When the depth is exceeded, it should be polished or polished after fine turning. After the flywheel thickness is processed, it should not be less than 2mm thickness of the new flywheel. The wavy depth does not exceed, allowing no more than two annular grooves, and burrs should be eliminated.

Check and adjust the yaw of the flywheel.

After the crankshaft and flywheel are mounted on the cylinder block, the yaw is checked on the working surface of the flywheel with a differential gauge. As shown in Figure 2-27. The flywheel rotates for one week, and the pointer swing difference shall not exceed to ensure the balance between the crankshaft and the flywheel and reduce the wear and tear of the clutch related parts.

Surface scratches can be removed by simple mechanical processing. Badly damaged flywheels should be replaced.

Hello. There is no impact on the use of peace of mind [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, generally the flywheel teeth are worn, and the motor needs to be replaced if it has a toothing sound. I hope mine can help you and have a great day! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello: The function of the flywheel gear is to ensure that the starter starting gear is properly engaged with the gear to ensure that the engine starts. Once the gear is severely worn or damaged, and it affects the normal start of the engine, it needs to be replaced.

When you can't get a taxi.

Hello, when the power is seriously insufficient, there is also a speed that cannot be increased with the increase of the throttle. It's possible that the flywheel is malfunctioning. I hope mine can help you [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The role of the engine flywheel ring gear:

1. The main function of the flywheel is to store the energy and inertia outside the power stroke of the engine. At the power take-off end of the crankshaft, that is, the side where the gearbox is connected to the power equipment;

2. The flywheel has a large moment of inertia. Since the work done by the individual cylinders of the engine is not continuous, the engine speed also changes. When the engine speed increases, the kinetic energy of the flywheel increases, storing energy; When the engine speed is reduced, the kinetic energy of the flywheel is reduced, and the energy is released and released.

The flywheel can be used to reduce speed fluctuations during engine operation. The main causes of the damage and maintenance of the collapse of the flywheel are mentioned above;

3. In addition, the flywheel also has the following functions: the flywheel is the driving part of the friction clutch; The flywheel rim is inlaid with the flywheel gear ring for starting the engine; The flywheel is also engraved with a top dead center mark, which is used to calibrate the ignition timing or injection timing, as well as to adjust the valve clearance.

What is the replacement technique of engine flywheel ring gear? Engine flywheel ring gear replacement tips:1

Dismantle the old ring gear: the ring gear and the flywheel are interference fit, and the ring gear needs to be heated first, most of which are about 300 (can be heated with a blowtorch or welding gun), and then washed down with copper or pressed down with a hydraulic press; 2.Criteria for selecting a new ring gear:

The interference of the outer circle of the new ring gear and the flywheel is that the fit between the new ring gear and the flywheel should be tight, and the interference amount is that the end face of the new ring gear should have a certain chamfer; 3.Install and configure the new ring gears: First, clean and dry the flywheel on which the ring gear is installed.

Heat the ring gear to 300-350 with waste engine oil to expand its inner diameter. When it is hot, it can be inserted vertically or pressed to the outer edge of the flywheel with a hydraulic press to check whether it is installed correctly, fitting, and natural. There is a certain tightness after cooling.

In order to avoid the loosening of the ring gear, it can be drilled every 1200 places and implanted with steel dust pins to fix. 4.After the ring gear is installed and configured firmly, it is still necessary to grind the chamfer of the gear teeth.

What are you referring to? Lock rings?

It is necessary to check whether the pre-starting device on the starter is faulty, which is commonly known as the suction package, which makes the starter and the ring gear slowly combine when starting, and can be replaced if there is a problem. The starter, also known as the motor, converts the electrical energy of the battery into mechanical energy and drives the engine flywheel to rotate to realize the start of the engine.

The starter gear ring may be: the static axial distance between the starter gear and the flywheel gear ring is too large, the standard is 3-5mm, or the meshing lily gear of the starter and the flywheel is seriously worn, or the one-way clutch in the starter is broken, or it is caused by the failure of the electromagnetic switch line, it is best to go to the nearby maintenance plant in time for maintenance inspection and replacement.

Maintenance: In the process of starting the engine, the starter should introduce 344 400Ah of power from the battery. Therefore, in order to prevent the battery from overcurrent or damage, the starting time should not exceed 5s, and the starting time should not be too long in winter, and there should be an appropriate interval in each start.
