The tire repair shop is designed for dismantling and mounting wheels and tyres, replacing tires, TP tubes and wheel rims, as well as balancing complete wheels.

At the same time, the washing and drying of the wheels before their dismantling, if necessary, is carried out here or in the UMR zone, where there is a hose washing installation. car service tire balancing

The technological process at the tire fitting site is carried out in the order shown in Figure 1.

Rice. 1. Scheme technological process at the tire shop

The wheels removed from the car at the post are transported to the tire fitting site using a special trolley. Until the start of repair work, the wheels are temporarily stored on a rack.

The dismantling of tires is carried out on a special dismantling and assembly stand in the sequence provided for by the technological map.

After dismantling, the tire and wheel disc are stored on a rack, and the camera on a hanger.

The technical condition of tires is controlled by a thorough inspection from the outside and inside using a manual pneumatic side expander (spreader).

Foreign objects stuck in the tread and sidewalls of the tires are removed with pliers and a blunt awl. Foreign metal objects in the tire can be detected during the diagnostic process using a special device.

When checking technical condition cameras reveal punctures, breakdowns, tears, dents and other defects. The tightness of the chambers is checked in a bath filled with water and equipped with a compressed air supply system.

A control inspection of the discs is performed to detect cracks, corrosion deformations and other defects.

It is mandatory to check the condition of the holes for the wheel studs.

Rim rust is cleaned on a special machine with an electric drive.

Minor defects of the rims, such as curvature, burrs, are eliminated on a special stand and using a bench tool.

Studding is carried out on a special stand, if the tire does not have holes for studs, they are drilled on a pneumatic drilling machine, which provides the necessary, high frequency of rotation of the drill.

Technically serviceable tires, cameras and wheels are mounted and dismantled at the same stand.

The air pressure in the tires must comply with the standards recommended by the manufacturer.

The tire fitting area is equipped with a reference pressure gauge, according to which the working pressure gauges are periodically checked. After mounting the tires, it is necessary to balance the wheels as an assembly on a special stand.

The tire fitting department is provided with the necessary technical documentation, including technological maps for the performance of the main types of work, and the corresponding technological equipment.

• safety requirements, industrial sanitation and fire safety.

1.3. Personnel must:

• perform only the work included in his duties or assigned work;
• master safe working practices;
• be extremely careful when carrying out tire work;
• comply with internal regulations.

1.4. During work, the following hazardous production factors may affect the personnel performing tire fitting work:

• moving machines and mechanisms;
• falling objects;
• dangerous level of electrical circuit voltage;
• increased surface temperature of equipment and materials;
• collapsing structures;
• increased air pressure;
• insufficient illumination of the workplace;
• increased gas contamination and dustiness of the working area air;

1.5. Personnel in their work must use the following PPE:

• cotton overalls;
• leather boots;
• respirator;
• goggles;
• combined gloves.

1.6. Mounting and dismantling of car tires should be carried out on a stand or on a clean floor (platform), and inside - on a spread tarpaulin or other bedding.

1.7. When dismantling the tire from the wheel disk, the air from the chamber must be completely released.

2. Labor protection requirements before starting work

2.1. Wear the proper attire.

2.2. Check the condition of the tool and guards.

2.3. Before removing the wheel, make sure that the car is securely installed on the trestle, and stops are placed under the removed wheels.

2.4. Before unscrewing the fastening nuts of paired discless wheels to remove them, make sure that the tire on their inner wheel has not come off the rim, otherwise it is necessary to first completely bleed the air out of it.

2.5. The chamber must be completely vented before the tire is removed. Dismantling the tire must be carried out on a special stand or using a special removable device.

2.6. Before mounting the tire, it is necessary to check the serviceability and cleanliness of the rim, bead and lock rings, as well as the tire.

2.7. When mounting the tire on the wheel rim, the locking ring must securely enter the rim recess with the entire inner surface.

2.8. Removing, setting and moving the wheels and tires of heavy-duty vehicles must be mechanized.

3. Labor protection requirements during work

3.1. When dismantling a tire from a disk that is firmly attached to the side of the wheel, it is carried out with a puller. It is forbidden to knock out discs with a sledgehammer (hammer).

3.2. Before mounting a tire, check the condition of the rim.

3.3. Tires must be free of dust and dirt before repair.

3.4. Roughing machines should be equipped with local exhaust ventilation for dust extraction and securely grounded.

3.5. Work on roughening should be carried out only in protective glasses.

3.6. Remove the chamber from the clamp after vulcanization only after the recovery area has cooled down.

3.7. When cutting patches, the knife blade must be moved away from you. The handle must be correct.

3.8. Containers with gasoline and glue should be kept closed, opening as needed.

3.9. Tires should be inflated in two stages: first, up to 0.5 kg per cm2. with checking the position of the lock ring, and then to the pressure prescribed by the instructions.

3.10. If the lock ring is found to be in the wrong position, bleed all the air from the tire being inflated, correct the position of the ring, and then repeat the above operations. Inflating tires without dismantling should be done if the air pressure in them has decreased by no more than 40% of the norm.

3.11. A pressure gauge or air pressure dispenser must be installed in the tire inflation area.

3.12. When using an electrically driven compressor unit to inflate tires:

• inspect the condition of electrical apparatus, pressure gauge (should be checked in the laboratory of the State Standard, there should be a red line on the pressure gauge scale corresponding to the allowed pressure);
• check the presence and serviceability of the compressor grounding and the availability of PPE (dielectric gloves, mats, tools with insulated handles);
• drain the condensate through the purge cocks from the air collector.

3.13. Before turning on the compressor, scrolling by hand, check for jamming.

3.14. Test the compressor at idle speed with air bleed to the outside according to the manufacturer's instructions.

3.15. After switching the compressor to the "Operation" mode, check the lubrication of the mechanisms, cooling and air pressure in the receiver.

3.16. To inspect the inner surface of the tire, a spreader (expander) should be used.

3.17. New tires must be equipped with new tubes. The same is recommended for retreaded tires.

3.18. Install tires with a directional tread pattern in such a way that the direction of the arrows on the sidewalls of the tire coincides with the direction of rotation of the wheel when the self-propelled equipment moves forward.

3.17. To remove foreign objects from the tire, use pliers.

3.18. It is forbidden to mount the tire on a rim that is rusty or has dents, cracks, burrs.

3.19. When mounting the tire on the rim, the retaining ring must securely enter the rim recess with its entire inner surface.

3.20. When inflating a tire with air, it is possible to correct its position on the disk by tapping only after it has stopped feeding.
