How to remove a gear from an electric screwdriver motor

With a puller

The problem when removing the gear from the motor is that it sits very deeply (near the engine itself), and therefore there is practically no way to slip the puller “jaws” into the necessary grooves for dismantling. This difficulty is observed on most models of screwdrivers and electric drills.

How to change the gear on the motor of an electric screwdriver. three methods:

  • Try to grind off the “lips” of the puller to make them as thin as possible. The operation is risky, because with excessive grinding, the “jaws” can simply break off during the dismantling process. In addition, this puller will no longer be used to remove other nodes, since it simply will not withstand the load. Therefore, this method can only be used if the puller was purchased only to remove a specific gear.
  • The second method is preferable if you need to remove a whole gear from an unnecessary engine (after work, it remains only to remove it or use it as a “donor” of spare parts). To carry out the operation, you must use a vise. The motor is placed in the clamp vertically. so as to crush the part that is near the gear shaft inside the engine. Of course, after the operation, the motor must simply be thrown away, since it will no longer be possible to use it. But there will be the necessary clearance and the ability to place a ready-made, fully functioning puller in its original position for dismantling.
  • And the last method can be used in a situation where the master needs the motor itself, but he no longer needs the gear. In this situation, it is necessary to make notches on the gear teeth with an angle grinder so that there is a place for installing the “lips” of the puller. It is important to ensure that the motor is not damaged when working with an angle grinder, which can easily slip off the work surface. After the operation, the gear will only have to be thrown out.

Many craftsmen, with an unsuccessful attempt to remove some unit of the unit, try to knock on it with a hammer, in the hope that it will move from its place, and it will be possible to dismantle it further without much effort.

Important! It is categorically impossible to knock on the gear, since it rests against the impeller located inside the motor.

In this situation, the impeller will simply come out of its grooves, and it will be very problematic to put it back. However, even after the successful return of the impeller to its place, in the process of operation in the future it will constantly jump out of its grooves.

If there is no possibility or desire to buy a puller, then you can make it yourself with your own hands. In terms of time, production will take about an hour, and everything you need should be in the garage of any master.

  • M5 tap for threading.
  • Several files that are in good condition: square, flat and triangular. They must be small.
  • Vise.
  • Wrench nut for 27.
  • Hexagon bolt with M5 thread.
  • One side of the nut must be cut almost to the very edge.
  • On the side, additionally cut a hole into which the gear shaft will be placed (made after measuring a specific shaft).
  • From above, above the side that was cut down, drill a hole and cut the thread with an M5 tap. The corresponding screw will be placed there, with which the gear will be squeezed out of the motor housing.

The puller is not difficult to make for a person who has dealt with plumbing work.

How to change a gear on an electric screwdriver motor

an electric screwdriver is a useful tool that is often used in construction work to speed up the process. Breakdowns on this type of device are not uncommon, and therefore you need to know how to fix them. One of the most common problems, which is also the most difficult to fix, is how to remove the gear from the motor of an electric screwdriver. The article will describe in detail how to do this with improvised means or using a special puller.

When is it necessary to repair or replace the gear

The most common problem in which you have to replace the gear of an electric screwdriver (for example, the Interskol model) is the motor itself burned out. In this case, you need to purchase a new engine, which already has a gear. But, there is an important nuance. the problem is that on an electric motor, the factory gear may not fit the gearbox that is installed on the electric screwdriver itself. In this case, it is required either to look for an engine that matches the size of the gearbox, or to perform an operation to replace a small unit.

Another problem: the chuck starts to spin during operation. This only indicates a malfunction of the gearbox, or rather, the gear, which does not cling to the teeth. This leads to cartridge overshoot. Failure of this unit indicates that the motor is not turning the spindle.

An experienced craftsman can understand that the unit in question is to be replaced if extraneous noises begin to appear in the gearbox during operation, and slippage or large jerks are observed during the spindle rotation.

Important! The gear begins to fail in most cases due to the fact that it is made of plastic. This option is often found on the cheapest screwdrivers (for example, “Metabo”).

The unit in question cannot be repaired even if it is made of metal, and therefore it must be replaced.

All operations that a master may think of to repair a gear will end in failure due to the small size of the unit and the impossibility of securely attaching the fallen teeth, and therefore it is not worth wasting time.

Important! After the direct replacement of the gear, it is necessary to apply a large amount of lubricant to it so that the operation of the equipment is as smooth as possible and the components do not wear out.

Is it possible to independently replace the gear on the electric motor of an electric screwdriver

It is possible to fix this problem on your own, but the operation is rather complicated (due to a fragile assembly that must be removed from a thin shaft), and everything must be done very carefully, since there is a risk of breaking off the teeth. Then you have to buy a new gear.

You can independently remove the gear from the motor of an electric screwdriver (for example, the “Bosch” model) using a lighter and pliers, or a thin U-shaped piece of metal. But experts do not recommend using this option, since there is a risk of damaging the teeth.

How to remove a gear from an electric screwdriver motor

To remove the gear from the motor of an electric screwdriver (or drill), you can use only two methods. The first requires a special puller. You can make it yourself, or try to find it on the Internet, for example, on the Aliexpress website.

The second option is not so reliable, since you will have to use improvised equipment that is not specifically designed for dismantling small parts.

Each of these methods has its own characteristics, which you need to know about before starting work.

Without puller

The operation can be performed without a special puller, but the risk of damaging the gear increases. The first step is to thoroughly heat the gear so that it expands and gets off the shaft better. To do this, you can use an ordinary lighter.

After heating, several removal methods are used (at the option of the operator):

  • If the motor is not needed in the future, you can use a flathead screwdriver as a lever, and the motor will serve as a fulcrum. To dismantle, you need to gradually push the gear away from you.
  • If the engine cannot be damaged, you will have to take a small and thin metal plate in the shape of the letter “P”. The edges of the plate should rest against the teeth. After heating, it is necessary to firmly but gently pull the plate.

How to remove a gear from an electric screwdriver motor

If you want to change the motor on your electric screwdriver, watch this video, there is nothing difficult about replacing the motor. The most important thing is to find a donor. All screwdriver motors are the same in size, they differ only in operating voltage and gears. It will not work to remove the gear from the shaft just like that, for example by knocking out, and if it does, then with damage to the gear. At home, I made the simplest puller from the materials available in 10 minutes, it quietly squeezes out such gears.

A puller so that you can pull off the gear from the motor of an electric screwdriver. I spied on the idea on YouTube, but there a man made it out of a very small nut. It took about an hour, an hour and a half, I did it from what was at hand, I found a tap M5, a couple of files, a triangular. flat and square, rampant bastardiness, a vice and most importantly, hands))))

I have not tested it yet, I decided to make a puller after I could not disassemble the engine from the Hitachi electric screwdriver to the screw

I wrote it for what, on Ali and in shops, such a puller costs from 400 to 1500 rubles, you can make it from what you have, even if you buy everything, then the nut costs 30 rubles in leroy, taps are 100 rubles maximum, everyone probably has a file. hands and time. The cut was made with an angle grinder, a cut-off wheel, the same circle and expanded.

A bit more Disassembly removing the gear

I disassembled the engine, the smell began to flow, it can be seen between the rotor and the stator dust began to fall.

Disassembled several (4) screwdrivers from different companies, all have the same Chinese motors. Coincidence?!

no, 550 were more likely all of him, there is still a little more and a little less

All were 12 volts, the older terminals were slightly thicker. Now they probably already put neodymium magnets on expensive equipment

motors for the cheap and expensive segment are standardized in terms of docking dimensions, expensive ones can have their own bodyless, brushless, etc., in cheap ones everything is the same and depends only on the manufacturer who collects, and the motor can be assembled at one plant, which is for the brand, which is for the Chinese, for example, Bosch in the blue series for 12v Shura put a standard motor, which is suitable for both Makita and Metabo, they are all compatible. The situation is the same with buttons. Akums, there is generally such a spread, all manufacturers put the cheapest banks, just brands put Samsung, false, etc., the Chinese are what is left))))

He also repaired a few, on shurahs from 9 to 14 volts there are the same motors.

you can always identify the driver of BMW. he very carefully overcomes all speed bumps, pits, potholes because repairing a BMW is a fiasco for the budget

Where can I find a video or any explanatory diagram that will help to independently remove the gear from the engine on the “Makita” electric screwdriver?

It is a pity that the brand of this screwdriver is not indicated, but I think that basically the line of this brand should be more or less the same. Since the sprocket on the engine is pressed in quite strongly, it can only be removed with the help of a special puller. Since pullers are still not available to all users of such wonderful equipment as Makita, I strongly advise you to contact a service center, where they will very quickly remove you and, if necessary, replace this part (most likely with high-quality, and not with that junk that is sold On the market). Well, if you still want to see how to remove this gear using a puller, then I advise you to watch a video on this topic here
