Idler bolt installation method automobile

1. Install a new belt : Reserve the position of the new generator belt in advance and start winding the belt from the idler side of the generator. During the installation process, you may need to use a tensioner or adjust the bolt to ensure that the belt is properly tightened. Check the tightness of the belt: After installing the generator belt, make sure that its tension is moderate.

2. Install a new iddler: Place the new iddler in the corresponding position and fix it with bolts or fasteners. Loosen the tensioner and install the belt: slide the belt back over the idler, and then use the tensioner to tighten and lock the belt.Check: Make sure that all parts are installed correctly and the belt is properly tightened.

3. There are two ways to install a single bolt. One is the hub bolt + nut. The bolt is installed on the hub through the over-over-over cooperation, and then the nut fixes the wheel. Generally, Japanese and Korean cars are widely used, and most trucks also use this method. The advantage of this method is that the wheels are easier to locate, easier to disassemble and install, and safer.

4.) As shown in Figure 59, align the marker A on the camshaft belt wheel with the pointer B on the rear cover, so that the camshaft belt wheel is set to the upper stop point position. 4) Install the idler with a new idler bolt (do not tighten the bolt first) so that the idler can move without falling off.

5. There are two ways to install single-head bolts, one isIt is a hub bolt + nut. The bolt is fixed and installed on the hub, and then the wheel is fixed by the nut. Generally, Japanese and Korean cars are more used, and most trucks also adopt this method.

Summarize the connections between bolts and nuts at the bottom of the vehicle?

1. First of all, a flat pad should be added to the bottom of the bolt, and then the bolt should pass through the workpiece in a direction that is convenient for maintenance. Add a flat pad, spring sheet, and finally add a nut to tighten. Nut, also known as Nut, is a fixing tool with a hole in the center and a thread on the inside of the hole.

2. Screw connection is suitable for occasions where the connector is thick and not often disassembled. The bolt (or screw) is directly twisted into the threaded hole of the connector without a nut. The structure is simpler and more compact than that of double-headed studs. It is used for a thicker one of the two connectors, but it does not need to be disassembled frequently to avoid damage to the threaded hole.

3. Double-headed stud connection Features: one of the connected parts is thick, blind holes are made on it, and threads are cut on the blind holes. Thin parts are made of through holes, no threads. Connect with double-headed studs and nuts. It is allowed to be installed and disassembled many times without damaging the connecting parts.

3. As long as there is external force or vibration, the bolt has a probability of loosening, but the size is different. The bolts of the car chassis may be loose, and there are usually several cases: long-term high-intensity bumps, such as youOn a good road running every day, the suspension system frequently experiences high-intensity vibration and vibration, and the probability of bolt loosening is greater. External force impact exceeding the design load.

4. Hello! Every time it is maintained! You have to do it once [If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

5. As long as there is an external force or vibration, the bolt has the probability of loosening, but the size is different. The car chassis bolts will also loosen. There are several situations: long-term high-intensity bumps, external impact exceeding the design load, and the connection bolts of rotating parts are more likely to loosen. So the screws on the chassis of the car will be loose.

Don't tighten car screws too much

1. Car screws don'tTo tighten it too much. Some car owners like to tighten the screws of auto parts by themselves, because they don't know much about it, and they will always tighten it too tightly, which is actually wrong.

2. The reasons why the car screw cannot be tightened too tightly is as follows: The reason for sealing: When sealing, the screw tightens the gasket is compacted and produces a micro-deformation, so that the micro-gap formed by mechanical processing on the surface of the connected object is fully filled to achieve the sealing effect. If the tightening pressure is too high, the gasket will be crushed or squeezed out without sealing.

3. The tighter the car nuts and bolts, the better. If they are too tight, they may affect the performance of the car, and even break the bolts. It's better to check the relevant information by yourself. It's always fake on the Internet. If you meet someone who pretends to know and answers casually, it will directly mislead you or even make you miserable.

4. Therefore, the screw must be twisted according to the torque parameters specified by the manufacturer during maintenance, for example, the torque wrench can be used to tighten the screw. There are many fasteners connected by bolts and nuts on the car. It should be ensured that they have sufficient pre-tightening force, but not too tightened.

5. That's definitely not this concept. Just tighten it. As the wheel rotates, the screw itself will become tighter and tighter. From the tire wrench of the car tool, use something about 50 centimeters to tighten it.

Are automobile suspension bolts subject to axial force

1. The bolt shear force is usually about 0.6 to 0.7 times the axial force. This is because in the process of bolt fastening, in addition to axial force, there are also transverse force and bending force.The action of these forces will cause the bolt to produce a shear force, and the magnitude of the shear force is related to the size of the axial force.

2. The bolt is pulled along the axis: In this case, the bolt bears the tensile force along the axis. In addition to considering the cross-sectional area and material strength, the length of the bolt and the influence of the connector on the bolt restraint also need to be considered.

3. And the helical gears on the second axis mainly generate axial force, and the needle bearing can withstand a large axial force, which can meet the requirements. Drill a lubricating oil hole in the gear of the two-axis to lubricate the needle roller bearing. For example, it can increase the stability of the car body and the stability of the chassis suspension.

When to replace the automotive magnetic screw

It is recommended that everyone replace the gasket of the oil release screw after each oil replacement, which can improve the sealing performance.The oil release screw is fixed on the oil sup, which is used to release the oil in the engine. If there is no oil in the engine, the engine cannot operate normally.

As long as it is disassembled and installed more than 10 times, it must be replaced. In large dump trucks, tire screws can be used up to 3 to 4 times, and then they can no longer be tightened. They must be replaced with new ones, otherwise the steel rim will be loose, causing the threaded holes to swell.

In order to clean up during the oil release process of each maintenance. This kind of magnetic oil seal screw can minimize the damage of metal impurities to the engine, reduce the run-in damage of the new car, and slow down the aging speed of vehicle damage. Therefore, replacing magnetic oil seal screws in car maintenance is an effective way to maintain and protect the engine.

Therefore, there is no need to replace the oil release screw.But some cars use plastic oil slas. This oil release screw is disposable and needs to be replaced every time. In fact, the magnetic screw is just a gimmick, and it is difficult to say whether it is useful or not.

Because the wheels have to jump up and down when the vehicle bumps, the connection part produces a certain torsion force on the bolt, just like screwing. Therefore, theoretically speaking, the bolt in the turning part is more likely to be loose.

Yes. It is necessary to change the magnetism of the BMW's magnetic screws, which can absorb the fine metal particles from the engine and some impurities in the oil in time. Magnetic screws are not easy to damage. However, when used on electronic products, it is easy to damage electronic products, affecting their accuracy and service life.
