If during operation the device emits extraneous sounds, this means that the bushings or the bearing are worn out. To fix this, you will need to disassemble the electric motor, and then check the integrity of the bearing and the level of wear of the sleeve. The anchor should rotate freely, there should not be any friction or distortion. These devices can be bought at a construction supermarket and replaced by yourself.

In all cases, it will be necessary to replace the defective gearbox elements. All the above steps must be followed carefully. Disassembly of the screwdriver must be done in a clear sequence, otherwise any of the parts may be lost.
Anyone can repair a screwdriver, you just need to correctly identify the faulty element.

PT Devolt702 ku, s, type 1 was brought in for repair. I looked at Dyatko in detail, there it is, but type 2, the question arises, are their anchors interchangeable? If anyone knows, please tell me.
I decided to repair the Soviet drill IE-1036E. It turned out that her armature had a break in several windings. While looking for a replacement, I opened the second drill, IE-1032-1, at its anchor the tip of the drive was broken off. Now I'm looking for two anchors, and different! I looked through a lot of things, the replacement revolves around AEZ products, but I can not find a catalog with a list of the main parameters of the anchors.

Hello, let's be friends with channels! I already liked and signed up!
They brought a rootless screwdriver, the marking is worn out, apparently China. The ratchet is triggered from the smallest load, you can fix it, but no, so take it in spare parts.
I checked the charger, batteries, engine, button - everything is in normal working condition.
Unscrew the screws securing the electric motor to the gearbox (if the motor is not fastened with screws, then we turn the gearbox relative to the motor, the gearbox is in front, the motor is behind, clockwise)
The three main reasons that lead to the fact that you have to do the repair of the screwdriver with your own hands are:
Diagram of a screwdriver device.
Any screwdriver has the following basic elements in its design:
Engine.
Reverse.
Reducer.
Regulator of turns.
The transistor of the speed regulator, which is connected to the radiator.
The repair of the device most often has to be done in connection with the occurrence of various malfunctions that are characteristic of cheap and expensive devices. Among them stand out:
When a screwdriver breaks down, the main percentage of malfunctions is the battery.
Broken battery.
Broken button for turning on the device.
Burnt out anchor.
The presence of whistles and various squeaks during operation.
Increased tapping of the clamping chuck.
The impossibility of regulating the speed of the screwdriver.
The reverse of the screwdriver does not switch.
The motor of the machine does not stop turning after the screwdriver is turned off.
The device turns on for a split second, followed by wedging.
Consider the features of eliminating each of the listed malfunctions.
In order to make sure that the screwdriver's battery is damaged, it must be checked with a multimeter.
The battery should be checked first before it can be replaced. The battery should be checked by routine measurement of the voltage level using a multimeter at the terminals of the device. You can also check with any other tester. In this case, there should be a coincidence of the output voltage of the batteries in working condition, if they are charged. The values 12V, 18V, etc. indicated on the battery cases must be strictly observed. If this condition is not met, then the device should be replaced.
Possible malfunctions of the screwdriver charger lead to the need to disassemble it, followed by checking using a tester that has already been used. Each battery included in a battery must be subjected to a similar test. After identifying the faulty elements, you should buy special elements of the same type with the same capacity in the store in order to install them in the places of the previous ones, replacing the old ones with new ones.
When repairing the power button, you must have special skills and relevant knowledge in the field of electronics. Disassembly of the apparatus should be carried out with the utmost care and care. Otherwise, opening the device can lead to the fact that parts of a certain type can easily fall out of the screwdriver.
It is best to first make a sketch of the order of arrangement of different springs, contacts and screws.
After you have made sure that the cause of the breakdown is in the battery, then it will be necessary to disassemble it.
When the case of the device is opened, the device must be checked for the presence of contacts that have darkened in it. If available, it is necessary to clean them with sandpaper.
When the switch has already been repaired, it is possible that the device will not adjust the number of revolutions if the trigger is pressed smoothly. However, the functions of the device are not lost when the trigger is fully pulled. In this case, the fault itself is associated with the adjustment circuit. In this case, a complete replacement of the switch is carried out.
If there is no reverse in the device, then it is replaced with a reverse switch, but you can also try to repair it. To this end, repairing the reverse is similar to repairing a switch button. The switch cover is lifted carefully.Then the contacts are checked, cleaned and assembled.
If burnt or deformed contacts are found under the cover, the reverse must be replaced. In the version of the button, when the reverse is assembled in its body, that is, inside it, the button changes completely.
In the event that, when the button is released, the screwdriver motor continues to work, then the button will have to be changed.
When, when the button is released, the motor continues to rotate, which did not happen before, then the button changes completely. The reason for the continued rotation of the button may be its release, which was not observed before. This requires a complete change of the button, or it is necessary to replace the transistor separately.
You can check the speed regulator using a multimeter configured for ringing the circuits. The governor circuit is not included in the general circuit acting as a result of the full push of the button. This is where the contact closure begins. Two wires are connected to the electric motor of the screwdriver, the same amount falls on the battery button.
The power button is connected to a regulating element or field-effect transistor through 3 wires, which is located outside the screwdriver body. It is necessary to connect the probes in order to dial the supply connected to the electric motor and to the input wire.
If possible, the probes are connected not only to the motor wire of the device, but also attached to the reverse input contacts. The device can show whether there is a contact or not. Further, in the same way, all measurements are carried out for the other wire, which is the input. Then you should move the reverse lever to repeat the measurements. If there are no contacts, then these changes affect the button.
The cause of the breakdown should also be looked for in the brushes of the screwdriver motor.
If all the elements of the device are in good working order, as shown by the operations that were carried out earlier, then it is imperative to check the condition of the engine brushes. This can be done by disconnecting the motor from the button by connecting a multimeter to its wires through the probes.
If there is little resistance in the circuit, then this may indicate that the brushes are worn out. In this case, the breakage of the anchor is not excluded, which can occur in rare cases. A winding break can also occur. In this case, a complete replacement of the engine is performed. If only the brushes are worn out, then you can restore the screwdriver motor with your own hands.
To restore the motors, for some models of screwdrivers, only the brushes are changed, and the element is not completely disassembled. For repairing other models, the back cover of the engine is separated with brushes from its body part. For this purpose, the flanging of the cover is bent without touching its edges, because they must be returned after the end of the assembly to their original place.
Flexible wire brushes are spot welded to attach to the holder. Soldering of wires for new brushes is possible. For this purpose, only refractory solder can be used.
Prolonged use of the screwdriver can cause the bearings to wear out or become clogged.
Before starting the assembly of the electric motor of the screwdriver using a thin wire, which serves as a clamp, each brush is removed in the brush holder, the cover is installed in its original place. In this case, the brushes release and bend around the body along the edges, which contributes to the best pressing of the back cover.
If the screwdriver works for a long time, then this may be accompanied by a process of curvature of the shaft related to the gearbox due to heavy loads and pressing the tool. The chuck, twisting around the shaft, sometimes causes a strong runout during the operation of the device. The support bush or shaft bearing can be severely worn. As a result of damage to the bush or only the bearing, and not the shaft, only replace them.
Sometimes it is impossible to start the engine for a certain fraction of a second, that is, it stops abruptly. This may be due to the failure of the gearbox. Often the malfunction occurs due to the breakage of the pin, which serves as an attachment to the satellite. It is possible to replace the carrier or the entire gearbox, which may fail if the gear teeth are worn out.
If, after carrying out all the above operations, no malfunctions were found in the device, then it is necessary to check the condition of the armature and the serviceability of the engine brushes. In this case, the engine should be disconnected from the switch button, and then the resistance should be measured by connecting a tester of any kind to the engine wires. If there is no resistance in the circuit at all, then this may indicate that the brushes are worn out. In this case, malfunctions in the motor armature are not excluded, which may be associated with a rupture of the winding. However, these types of problems may rarely occur.

If the engine armature is completely burnt out, then the device engine is completely replaced. If only the engine brushes are worn out, then it is better to repair the device yourself. Before starting repairs, gently open the screwdriver motor housing so as not to damage its edges. All stages of work related to the replacement of brushes are indicated above. It is possible that the armature bushings were worn out due to the magnet, which came off and began to come into contact with the armature. After dropping a drop of special oil on the bushing, turn off the engine to wait until the oil has dispersed in all bushings. However, it still requires replacement over time.
