How to scrap the tires of a car without a tire scraper? 20

The first step is to prepare the tools and equipment needed for the whole process of disassembling car tires, a tire wrench, a small hook, both of which can be found in the trunk of the car, and a jack.

The second step, the disassembly of the tire screw cap, take out the small hook, hook the hole of the screw cap with a small hook, and then pull it out to remove the screw cap, a total of 5, take it off one by one, the third step, take off the screw cap to be placed in a small box to avoid loss.

Fourth, the initial loosening of the car tire screw, take out the tire wrench, use the tire wrench stuck on the screw, and then turn counterclockwise to loosen all 5 screws.

The fifth step is to support the place where the tire needs to be disassembled, take out the jack, find the support point of the stiffener in the place of the chassis, and then use the jack to support the vehicle.

Sixth, take out the tire wrench again, disassemble the 5 screws that were loosened before to fix the tire, and put the disassembled screws in the previous small box.

Step 7: We can remove the tires of the car, hold both sides of the tires of the car with both hands, and then lift them out.

First of all, the tires should be cleaned comprehensively, including the surface of the tire, the contact surface between the wheel and the rim and the bolts and nuts on the wheel, and the rust, slag and mud on the wheel. The main purpose of cleaning is: first, to reduce the impact of dirt on the repairer in the process of disassembly and assembly; The second is to reduce the amount of dirt entering the inside of the tire and reduce unnecessary secondary injury.

2.Lubricate the grooves of bolts and nuts before dismantling to facilitate disassembly and reduce wear. Use a matching torque wrench, leave a spacing of 2-3 nuts, and disassemble them in the order of the diagonal, which can effectively reduce the irregular force on the bolt and reduce the fatigue loss of the parts.

If you choose a motorized wrench, you need to adjust the air pressure, which depends on the size of the nut.

3.Place the lock ring of the wheel upwards to release the air from the tire, and push out the valve when the inner tube tire is deflated. Make pairing marks on the tires and rims. Note: The gas in the tire must be cleaned to avoid accidental injury accidents in subsequent operations.

4.Insert the straight guide vane plate between the rim ring and the tire, and press down the bead of the tire; Insert the vane guide plate at the gap formed so that the end of the vane guide plate is supported in the flange ring, and the top of the shaft head rests on the straight guide vane plate.

5.Remove the tapered edge of the lock ring from the tire by pressing down the tire bead on one side and moving the straight and curved vane plates along the circumference of the wheel on the other side.

6.insert the end of the straight guide vane plate into the notch of the locking ring, and press the locking ring out of the groove; Lift the locking ring upwards, support the bent vane plate in the rim ring, and insert the end of the straight vane plate into the lower end of the locking ring; Hold the lock ring in your hand and remove the lock ring from the groove of the rim with the straight guide vane plate.

7.Take out the rim ring, flip the wheel, take off the side of the tire from the wheel with the help of straight and curved vane plates, and then place the wheel vertically, first take out the rim from the tire, and decisively beat the rim from the tire by punching along the locking part of the wheel with a hammer. If you have a tube, you can take out the inner tube.

Although many tire repair shops now have professional disassembly tools and even professional machinery and equipment, such as: special tire removal machine for truck tires. But the principle of disassembly is the same, and you must be careful during operation

1.When disassembling the tires to be replaced, it is important to note that you should not use a jack when you come up.

To lift the car up, you should first use a socket wrench.

Place the tire set screws diagonally.

Unscrew the sequence and then use a jack to lift the vehicle partially. If you lift the car first, you will find that you cannot unscrew the set screws because there is no force point.

2.When disassembling the fixed wheel screws, pay attention to the direction of force: the counterclockwise direction is loosening; Tighten in a clockwise direction. In addition, since the screws that hold the wheels are tightened, we can rely on the strength of the whole body.

3.After loosening the screws one by one, we can use the jack to partially lift the vehicle. When using a jack, pay attention to the fact that there are card slots for placing jacks on both sides of the bottom of the car, and be sure to place the jacks in the card slots to avoid accidents.

4.After the jack is propped up, the loosened screws are easily unscrewed in turn, and then the tire can be removed as a whole, which means that the tire disassembly is successfully completed.

The manual tire scraper is the latest improved product launched according to the market demand, and its performance and quality are more stable and reliable. The tire scraper also dismantles the tire, loads the tire, and inflates it in one, and also has the right auxiliary arm and other devices to make it more convenient, safe and reliable to disassemble and assemble the wide flat tire. It is suitable for dismantling, assembling and inflating tires of various small and medium-sized cars, and is a powerful assistant for auto repair shops and auto tire shops.

The automatic tire scraper and tire removal, tire installation, and inflation in one, and the unique right auxiliary arm and other devices make it more convenient, safe and reliable to disassemble and assemble wide flat tires. It is suitable for dismantling, assembling and inflating tires of various small and medium-sized cars, and is also a powerful assistant for auto repair shops and auto tire shops.

Tire scrapers are generally used, and the operation steps are as follows:

1. First of all, the equipment and sundries that hinder the operation on and near the tire scraper should be removed, and all parts of the machine should be checked to see if they are normal. Secondly, when picking the tire, completely drain the air in the tire and remove all the lead on the steel rim.

2. Put the tire in the tire extrusion position, use the wheel rim to detach the hoof to compress the tire and make it separate from the steel ring, so that the tire and the steel ring are completely separated, and the hands and feet should be prevented from going deep into the extrusion arm during the extrusion process. Pay special attention to be sure to deflate the tires when performing this step.

3. Lift the tires on the disassembly and assembly table, at this time you should avoid bumping the equipment, step on the pedal to support (or clamp) the steel ring after the tire is placed, and it is not allowed to use your fingers to detect whether the steel ring is aligned.

4. Install and disassemble the bird head, pay attention to the fastening and the position of the bird head from the steel ring. The best position is centimeters, and it is fastened after adjustment.

5. In the process of disassembling and assembling tires, when using a crowbar to pick the edge of the tire to the bird's head, you should pay attention to the direction and strength of the crowbar, and never allow your hands to go deep into the gap of the prying.

6. At this time, press the rotation pedal to rotate the workbench of the tire scraper clockwise, and the outside of the tire can be removed.

7. The inside tire can be removed in the same way. Pull the tires out of the rim.

The tire removal machine (also known as the tire scraper) can easily and smoothly disassemble and disassemble the tire during the car maintenance process, which is convenient for tire repair and replacement.

Try to keep the head close to the rim when you disassemble it. While dismantling, replace the tire removal head and press down and move it outward.

The boom and boom are used as pillars, we drive the scraper to an open field, and then let the leader of the scraper drive the boom and boom, the bucket touches the ground, and the boom and boom support the front wheel of the scraper. Then we find a jack and put the steel plate on the side of the flat wheel, check the puncture position of the inner and outer tubes, remove the foreign objects on the tires, and make marks for us to find, remove the outer tires, and repair the tires.

We can remove the inner tube, fill it with air, put it in the pool, check the inner tube one by one for air leakage, and then check the outer tire for damage. If the damaged surface is small, it can be continued to be used, and if the damaged surface is large, it should be checked and repaired in time. For tires with hard seams, it is best to use the spring steel plate of the trolley when tearing the tire.

It's easier to press the opening of the tire against the bird's head with a homemade elongated pig's foot. When you load the tire, press the belly of the tire with both hands. When the gap is about 200mm and the fetal opening is at its narrowest, press the belly with your right elbow.

At the same time, push the tires clockwise with your left hand, which will prevent the engine from slipping along with the V-belt and protect the engine.

I would like to explain a fact that almost everyone understands. For some configurations, the original option is cheaper than the externally installed one due to volume cost control, but for some of the original configurations it is ridiculously high. The ** given is really convenient, you should be very clear, I don't know if you remember that once a Mercedes-Benz S broke into the door to buy parts, and actually recovered almost two Mercedes-Benz S money, which proves that the zero vehicle ratio is still very exaggerated.

Start the loader, find a relatively flat and open place nearby, press the boom lever, use the bracket to lift the front wheel off the ground, and then use the bracket to place it on the side of the front axle near the tire break, and lock the rear wheel (work closely with the driver to avoid personal injury). Use the lift bar and other tools to remove the support ring and locking ring, and then check that the tire platform adheres to the outer surface of the circle (if the tire is used for a long time, the tile and outer surface of the tire can be respected, if needed, remove the bracket and let the car slide slowly back and forth for a short distance until the tile separates from the outer surface of the circle; Driving and high-speed driving are prohibited. r to avoid damaging the inner tube.

Thus, the front wheels are supported from the head.

Find a stable place to press the boom dry.

Will the tire scraper hurt the tire? When changing tires, you can avoid scratches on the rims. When using a tire scraper to change tires, the master will apply special lubricating oil to the rim and tire, which can protect the rim and tire, and can also effectively avoid scratches.

The tire is a more important part of the car, this part is the only source part of the car in contact with the ground, and the tire is related to the driving stability and driving safety of the car. 2. Material: Tires belong to rubber products, and rubber products will be aging after long-term use, so tires need to be replaced regularly.

When buying new tires, it is also important to look at the production date of the tires as they also have a shelf life. 5. Warranty: Under normal circumstances, the shelf life of the tire without Hu Xiao is three years, if the tire leaves the factory for more than three years, then it is not necessary to buy the trouser draft.
