Repair of any equipment involves parsing. A screwdriver is a common unit, it is available in every home. Its breakdown occurs at any time and it is not always possible to contact the master. How to disassemble a screwdriver? Without this, you can not do in the repair process. All units have an identical device, so the principle of operation is approximately the same.
Breakage and device
Before disassembling a screwdriver, it is worth examining its device. This includes a number of functional units:
- Start system.
- Regulator.
- Engine.
- Transistor.
- Planetary reductor.
Each node is located in a housing made of durable material. There is a control button, a pen, a place for the battery. On sale there are units that can only work from the outlet. Performing a start at low speeds, a squeak appears. This is a normal occurrence. Carrying out the work, do not worry about the fact that he fell into disrepair.
There is a ratchet, the task of which is to limit rotation when the cartridge moves. The location is easy to understand - the ring undergoes rotation. It helps to understand how deep a bolt or self-tapping screw goes. If the work is carried out with soft material, then the fasteners sink there, sometimes it goes right through. The task of the ratchet is to keep the tool in working condition and not allow the cutting of the hats of the screws.
Increasing the number allows you to make revs frequent. The right choice is made depending on the work. Often there is an icon in the form of a drill on the screwdriver, which means that this function is applicable in the work. When switching, the speed becomes maximum.
What kind of breakdowns are there?
Before disassembling a screwdriver, everyone should study the information about which failures are most common. Conventionally, each tool, regardless of brand, has typical breakdowns. It is worth highlighting:
- Battery malfunctions.
- Damaged brushes.
- Buttons fall down.
- The cartridge vibrates or beats.
- It does not turn on, off.
- Unstable work.
Each person is able to cope with such violations himself, but only if he has experience working with measuring instruments and a soldering iron. More difficulties arise when the gearbox or motor breaks down. In such a situation, it is better to contact a service center. Do-it-yourself screwdriver repair procedure has several main stages. The instruction should be the basis.
How to repair?
Before disassembling a screwdriver, it is worth roughly figuring out what the problem is. After the housing is removed, the main components are disconnected. Do not violate the correctness of actions:
- The battery is removed.
- The screws securing the housing are removed. It has a lot of them, so each screw is carefully cleaned so as not to break the case.
- Detach the top. The entire internal set should be removed.
- Dismantle the button. This is the most difficult because it is fixed to the main motor system by wires. They can not be torn and broken.
- Remove the speed switch.
- Dismantle the gearbox, motor, clutch, cartridge. Most often you have to unscrew the fixing screws, you can not miss a single one.
Thus, the Whirlwind screwdriver and others are disassembled. The difference between the systems is insignificant - the instruction is suitable for each model. After that, the repair begins.
Cartridge Recovery
The part, depending on the brand, has a different mount to the shaft. There are few ways:
- Morse cone.
- The presence of thread.
- Thread and screw for fixing.
There is useful information on the bottom of the appliance body. Instructions should be at hand. How to disassemble a threaded chuck:
- Release clamps.
- Remove the screw by turning it clockwise.
- The hexagon is fixed in the cartridge and pressed (it should be started or hit the unit). It’s easier to unscrew the part.
To disassemble the cartridge, it is worth removing the plugs, depending on the material (plastic or metal) a tool is selected. There are many problems with this component:
- The bolts are fixed unevenly.
- The gap between the bat and the cam.
- Cams go out incorrectly.
Sequence
Repair is carried out strictly according to the instructions, any deviations lead to a new breakdown:
- The cartridge should be disassembled.
- The flare nut is dismantled (it is bisexual).
- The jaws must be removed by unscrewing them.
- View thread on fasteners. In the event of a breakdown, the details change.
- The cartridge is going. It is necessary to memorize the sequence of unwinding so that when recovering, one is not mistaken.
When the thread on the cam or nut breaks, it’s difficult to get the part. The only way out is to remove it from another tool. Often when the cartridge breaks, it is completely changed. At the Whirlwind screwdriver, the parsing procedure is identical. When choosing a new part, the old should be available for example.
Gearbox repair
It includes:
For the manufacture of using two materials - plastic, metal. To make repairs, you need to know how to remove the screwdriver gear. The gear has cylinders with internal teeth fixed around the perimeter. And already on them is the movement of the satellite. The engine transfers the rotational process and work begins. After detecting a breakdown, it is worth analyzing:
- Dismantle the cartridge.
- Remove all fixing fasteners on the housing.
- Disconnect wires from gearbox to motor.
- Remove the plates.
- Pull out every part in the housing. Be sure to follow the sequence.
- To disassemble the gearbox itself into two parts, the fasteners are removed.
- Check the spring so that the gear passes faster.
- Remove the snap ring, washer, bearing (this is a disassembly of the coupling).
- Carry out shaft removal.
How to disassemble and assemble a screwdriver? So that the assembly does not cause difficulties, each part is arranged in order. When the work of a screwdriver is accompanied by unusual noise, damage to the gearbox gives such a change. After the analysis, it will become clear that it has become unusable. Replacement is usually subject to bearings and support sleeve. If after starting the engine stops, you will have to replace the carrier or gearbox. If the gear wears out, work is carried out with the gearbox. There are enough failures, but sometimes it is enough to disassemble and lubricate. Do not do too much, otherwise the work will become poor in the future.
Button violation
When this part fails, the following is observed:
- Unauthorized traffic.
- The device does not turn on.
- There is no constancy in work.
From the button there are several wires to different components - the battery and the engine. You need to know exactly what the problem is in it:
- The voltage is checked, it should not be in the button.
- The battery is removed and the upper motor cable is removed from the button itself.
- The engine turns on directly. In the absence of malfunctions, the button is out of order.
How to disassemble a screwdriver button?
The instruction is simple:
- You should not get rid of the connecting wire. The bottom of the button is removed.
- Remove the protective flap. This will require a screwdriver. They tidy up and clean it, remove the compartment cover. If the contacts are soot, they remove it. Often it generally burns out, then undergoes a complete replacement.
- Lock the spring to pull out the trigger mechanism. There may be dust inside. It interferes with proper operation. Everything is well cleaned.
- Another failure is the transistor. The contacts are cleaned, then the device is assembled. The transistor is replaced, after collection, a performance check is performed.
Depending on the cause of the breakdown, they analyze the screwdriver. There is no need to do unnecessary processes, otherwise everything cannot be returned back.
