How To Lubricate The Punch Reducer

How and with what to lubricate the gearbox and the drill chuck?

Welcome to my site! This article will focus on lubricating a rock drill. The operation of this tool requires more than just simple respect. It is imperative to periodically lubricate the gearbox and chuck.

In this case, the gearbox, of course, comes already lubricated from the factory. But over time, the lubricant leaks somewhere, dries somewhere. In addition, it is only intended to reduce friction, not to eliminate it. Therefore, one way or another, and the parts still rub against each other, due to which fine metal dust is gradually formed, which remains in the lubricant.

As a result of this mixing of metal and lubricant, the properties of the latter are gradually lost and wear of parts is accelerated.

The cartridge is dry from the factory. Here, in fact, not one cartridge is completely smeared, but only that place of it that comes into contact with the drill, since it is in it that strong friction occurs, and not reducing which can damage both the cartridge itself and the drill shank.

So, below we will consider how and with what to lubricate these elements. An SDS rotary hammer with a horizontal engine will be considered, since it is it that is used by home craftsmen in the overwhelming majority of cases, and the article is mainly written for them.

Gearbox grease

A special lubricant is used here, which should be called so. Gearbox. It can be as under the brands under which the perfs themselves are produced. Makita, Bosch, AEG, etc.

How To Lubricate The Punch Reducer

But it can also be produced by a company that deals with this particular type of product, for example, Ravenul, Shell, Xado, etc.

Some people use for THESE purposes and simple lithol or salidol. But in comparison with special lubricants, they dry faster, and they DO NOT eliminate friction as much as necessary.

Drill grease

Everything is exactly the same here. Special greases for this purpose are called so. For the Boers. And also themes are usually produced by the same firms that do punchers.

In the absence of a special lubricant, you can use graphite. But it does not remove heat from the shank so well, and this is important, since sometimes during prolonged work the shank sometimes becomes flattened, which is why it is difficult to extract it later.

How to lubricate a punch

Different types of lubricants are used to lubricate the gearbox and drill chuck.

We lubricate the gearbox

You will need to disassemble the tool body. Follow the points:

  • Let’s analyze the cartridge. To do this, first remove the rubber ring. Then pry up with a screwdriver and remove the retaining ring. Next, the outer casing of the cartridge is carefully removed, and then the clamping ring, ball and spring are removed.
  • Now unplug the mode switch. This is done differently depending on the model. At the end of the article, I gave a number of links to, which tell how he is removed in one or another model. If among them there is your unit, then you can look at any similar one to understand the principle. And then, I think, it will not be difficult to disconnect it and at home.
  • Free the collector from the brushes. To do this, unscrew the rear housing cover and remove the brushes.
  • Unscrew the self-tapping screws that pull the body longitudinally and disconnect it.
  • Remove the gearbox together with the motor armature.

Now thoroughly rinse the gearbox itself, as well as the inside of its housing. Flushing can be carried out, for example, with gasoline.

After that, the most critical parts are first smeared. And then the entire gearbox is completely coated with grease.

Well, it remains to collect everything in reverse order.

Lubricate the chuck and drill shank

This operation is very simple, so its description will be rather short.

We just take the drilling lubricant and add it directly to the chuck. Another option involves applying it to the shank and then installing it into the socket of the cartridge. But no one forbids combining these two methods for reliability.

It is necessary to ensure that the grease is constantly present and, as necessary, add a new one. If this procedure is neglected, the shank will overheat, which will either tear it off the rest of the drill or flatten it. So DO NOT be lazy and add.

That’s all you need to know about the chuck and shank.

As I promised, I am attaching at the end of the link to the disconnect switch:

This is all the information I have regarding the lubrication of the hammer drill. I hope it was clear and accessible. On this I say goodbye. Until next time!

What is hammer drill lubricant and why is it needed?

Lubrication. It is a viscous substance designed to minimize the coefficient of friction between parts of the tool. Reduce, not completely remove. That is, this means that friction between the parts is almost always there, and at the same time some of the small particles are separated from the tool and get into the oil itself. After a while, this grease saturated with metal dust does NOT perform its direct function. At first, its viscosity simply changes, and later the lubrication itself is a prerequisite for the rapid wear of the tool parts. Viscosity is considered the main parameter that you need to pay attention to when buying it.

The manufacturer must indicate in the technical documentation all the characteristics of the tool and the lubricating mass to be used. Much attention should be paid to the frequency of maintenance, where it is indicated after what time it is necessary to change the lubricant.

For a hammer drill, which has a quality certificate, it is imperative to use only branded lubricants, otherwise, after the tool fails, you will lose the right to warranty service. After the warranty period has passed, it is also better to use the lubricant recommended by the manufacturer, but at this time, most often, the user uses cheaper domestic counterparts. Litol or grease will NOT harm your instrument in any way. But do not forget that lithol is produced much faster, that is, it needs to be replaced much more often.

Is it possible to disassemble the rotary hammer reducer itself?

The tool reducer requires a lot of attention. It is not so difficult to lubricate the gearbox parts, but by the end of the warranty period, it is undesirable to lubricate the hammer drill. You will be able to disassemble the gearbox in any case, but not everyone can assemble it. With the problem of lubricating the gearbox, it is advisable to contact the company service center or specialized workshops. This is a rather delicate job, therefore it is advisable to entrust it to professionals. But there are times when this nearest center is far from you, so you need to lubricate the gear yourself.

Pay attention to all details during disassembly. Some of them have absolutely no lubrication. This does not mean that the lubricant has already been used up. It’s just that some of the gearbox parts are NOT machined. You don’t need to lubricate them either. During disassembly, we try to remember as much as possible the location of the parts and the sequence of their disassembly. Thus, you will not have “extra” parts during assembly. All parts of the gearbox must be thoroughly washed with gasoline (or with a spindle) and wiped dry with a cloth. It is also necessary to wash the gearbox housing inside. It is not worth hurrying with the assembly: let the housings dry well.

How to lubricate the gearbox in a rock drill: lubrication and work steps

Every tool needs timely maintenance, and the hammer drill needs it first. After all, the work of this tool is accompanied by a huge number of reciprocating rotations and movements, and the volume of dust emitted from the working object has a high concentration. Under THESE operating conditions, careful maintenance of the device and timely replacement of the lubricant in the perforator gearbox are required.

Most users believe that if grease is present, it can be used indefinitely. This opinion usually exists among users due to the poor level of knowledge of the laws of physics, so let’s talk about the mechanism of the lubrication in more detail.

How to choose a drill lubricant?

One of the most popular products is diesel engine oil. Graphite lubricant is also quite good, it is often used for open worm gears. Litol 24 is also popular, but this lubricant also causes braking and additional heating. Yes, and it works for a short time, unlike branded grease for a hammer drill and for cordless tools, it is extremely undesirable.

Maintenance features Electric drill with punch function

It is much more difficult to maintain an electric drill, which works with a hammer drill function. This hybrid of tools has some disadvantages as opposed to a conventional rock drill:

  • There are special containers for filling the lubricant;
  • It is much more difficult to maintain the drill chuck.

Permanent lubrication is required only for the drill bit. The amount of lubricant is minimal: it is enough just to clear the storms of dust and apply a small (the size of a match head) amount of grease to the tip. The same requirements apply to the lubrication of a brown conventional rotary hammer. An excess amount of grease on brown will NOT harm the tool mechanism, but it will splatter in any case and can damage the repair of the room. But if the grease is brought into the gearbox in an excessive volume, then it will simply leak out.

There is little to say about professional rock drills. In home use, this tool, as a rule, does not exist. Here, first of all, the price of the instrument plays a role, therefore, it is chosen much less often. But at the same time, this tool is considered the simplest and most unpretentious to use. There are usually no problems with the lubrication of this tool, because the design of the mechanism is very simple.

The gearbox also does not have any features that make it difficult to maintain. It’s simple: we unscrew the drain valve, pour the used grease into the container, rinse the punch grease container, twist the drain hole and pour new grease at the desired mark. The gearbox of this rock drill is serviced in the same way as described above.

Why the hammer drill is overheating?

And now we lubricate all parts of the gearbox and assemble it in reverse order. Do not forget that excessive amounts can also affect the performance of the tool: the heating of the gearbox may increase significantly.

If the rotary hammer began to heat up more than usual during operation, this does NOT mean that there is a problem with lubrication. Most likely, you used the chiseling mode for a very long time and the lubrication simply did not pass to all parts of the hammer drill in the right amount.

Another reason may be a clogged motor cooling hole. In this case, there is only one solution: to clean the tool from dust and switch it temporarily to another operating mode. If the hammer drill works for half an hour like a regular electric drill, the body temperature will drop significantly. The gearbox must have the same temperature in any mode of operation of the rock drill.

What it is?

Lubrication. It is a viscous substance that reduces the coefficient of friction between tool parts. The work of the hammer drill is associated with a huge number of different rotational movements, which increases the degree of wear of structural elements.

What parts need lubrication?

According to their physicists. Technical parameters grease for drill, piston, drill, as well as gear and other elements Almost does not differ from greases of all other types. It is a rather viscous substance of oily structure, it is used to reduce the frictional force of rotating parts, thereby reducing wear on the operating mechanisms.

Over time, the grease becomes impregnated with dust, which is formed during drilling, grinding and crushing. This leads to a change in the degree of its viscosity. In this situation, friction, on the contrary, increases and the wear rate increases, so the lubricant should be renewed from time to time. In order for the perforator to serve longer, you should clearly understand which parts can be lubricated and how often it should be done.

The device has a complex structure, including several complex units:

  • Anti-vibration casing;
  • An electric motor is located horizontally or vertically;
  • Piston system;
  • Cartridge;
  • Housing-shaped gearbox. It contains cylindrical bevel and worm gears;
  • Clutch required to stop rotation;
  • Working nozzle (drill, as well as a chisel, lance or blade).

Almost all hammer drill mechanisms are subject to lubrication.

  • Reducer. This is a mechanism responsible for the rotation speed of the main working nozzle. It protects the parts located inside from dust and dirt, therefore it is equipped with a protective coating. During the operation of the tool, its parts experience huge loads due to the constantly increasing friction between them, which, in turn, leads to rather rapid wear.
  • Cartridge. In addition to the gearbox, you need to lubricate the cartridge, as well as the landing site of replaceable nozzles. The cartridge is initially dry, therefore, after purchase, it should be lubricated in the area in contact with the tail of the nozzle. This is where the maximum friction occurs. If it is NOT reduced in a timely manner, then the degree of wear increases sharply, which quickly leads to its damage.
  • Tail nozzle. This part wears out under the influence of impact forces, which, when heated, increase its abrasion. Shanks must be lubricated every time they are installed, but before that you need to wipe off dust with a cloth and remove all dirt.

Rotary hammers can operate in different modes depending on the features of operation. Some use the instrument daily, others. Only from time to time, so there is a clear answer in the frequency of lubrication of the working parts of the tool. Usually, the operating instructions clearly describe the procedure for lubricating parts.

When deciding to change the lubricant, they are guided by the moments:

  • Perforator use frequency;
  • Tips outlined in the user manual;
  • Warranty service period.

Features of the choice of oil

One of the main parameters that is taken into account when buying a lubricant. This is the viscosity of the oil. High quality products are usually expensive, but in this case, you do not need to save. The perforator is an expensive tool, so you should constantly take care of its performance. Usually, the types of grease are listed in the instructions, but if information is not available, then you can always seek advice from the manager of the service center or sales point where the device was purchased. Experts will select the optimal composition for the perforator.

There are also universal compounds, which can be used to lubricate different types of drills. In recent years, graphite lubricants have been very popular because of their good viscosity and high quality level.

Experienced specialists confirm that many branded mixtures are of much lower quality than mixtures Produced on the basis of graphite. In addition, they have a fairly affordable cost, so many people confidently make a choice in their favor.

For perforators, you should take substances such as grease and lithol. Litol. 25. High quality material with long use, which has a low cost. Therefore, it is very popular among power tool owners.

Do not forget that such mixtures can cause slight braking of rotating structures, and can also significantly increase the heating of the tool during operation.

And in order to lubricate the gearbox, a more liquid composition is required, which must completely cover the contacting parts. We fill the free cavities. But if there are plastic parts in the gearbox, then the lubricant can only be silicone.

The transmission mechanism can also be lubricated with plastic compounds, however, not every technique can function without interruptions when using means with a similar consistency.

Thicker mixes are suitable to reduce wear on the tail nozzles. Usually the packaging indicates that they are intended for processing brown.

For cartridges, silicone grease options can be used. Lubricants are branded, which are manufactured by manufacturers of electrical tools, for example, Hitachi or Metabo, as well as AEG, Bosch or Interskol. They can also be produced by enterprises specializing in the production of lubricant mixtures.

The following brands are most in demand:

  • Bosch. Produces oils for gear lubrication and tail nozzles;
  • Makita. Purchased for drills;
  • Lubcon Thermoplex. Produce products for gearboxes;
  • Turmogrease. Universal greases;
  • Nanotech. Used for shanks;
  • Interskol. Optimal for handling brown;
  • PRORAB. It is a composition used for the treatment of tailpieces;
  • Kress. Used for lubrication grease boring.

Rotary hammer lubricants: what it is, how to choose and use?

Rotary hammers require careful maintenance during use. Various types of lubricants are used for their long-term operation. Compositions can be mineral, semi-synthetic, and synthetic. Mineral minerals are made from petroleum products, therefore they quickly lose their operational characteristics, and they have to be changed quite often.

It is very important to choose such a composition, which will be suitable for the selected type of perforators.

How to properly lubricate parts?

When it comes to lubricating a hammer drill at home, as a rule, it means changing the lubricant on its SEPARATE parts on your own. Lubricate the gearbox first. This mechanism is quite simple to understand, but it has a complex structure, so all actions must be carried out in a strictly defined order.

First, you need to prepare the necessary materials:

  • Dry clean cloth. Rags;
  • Locksmith tools, which are required to assemble the gearbox;
  • The lubricant itself.

In most cases, world-renowned manufacturers such as Bosch and Makita, in the operating manual, indicate the entire procedure for disassembling and assembling devices and issue important recommendations. The owners of rotary hammer drills, Who are faced with such work for the first time, following these tips, can master all the manipulations quite quickly, with a minimum of effort.

But if such a guide is at hand, then you should work according to a certain algorithm.

  • The tool must be removed from dust and dirt.
  • When disassembling and then assembling the drill and hammer drill, it is necessary to remember as accurately as possible the order of arrangement of all functional parts so as not to confuse them during disassembly. Better to use the commit.
  • All work related to the lubrication of parts is performed only after a certain time after the stop of the drill. It must cool down, otherwise the cooled grease may cause the power tool to malfunction if it comes into contact with Hot spots.
  • After taking out all the basic parts, including the gearbox, they are washed with spindle oil or gasoline, and then thoroughly dried from excess moisture. Pay particular attention to the gearbox.
  • Every detail of the device should be inspected as carefully as possible. Some areas have grease. This means that it is not necessary to apply a new composition to this place.
  • After applying the composition, the gearbox is carefully assembled in the reverse order. If done correctly, the hammer drill can be used immediately.

In addition to the gearbox, Storms should also be lubricated. In this case, the tail of the mechanism, as in the first case, is washed with gasoline, cleaned and dried, and only after that it is carefully coated with specialized oils.

At the same time, it makes sense to process the cartridge oil seal with your own hands, this will significantly increase the period of its service, and also protect against dust penetration. However, one should not lose sight of the fact that it is lubricated only when a system with an open type chuck is mounted on the perforator. If the system is closed, there is no need for lubrication.

Gearbox lubrication

The perforator gearbox is the most complex unit of the device in terms of design, therefore it requires special attention. It is not so difficult to lubricate the perforator gearbox, but self-assembly of a pre-disassembled unit can cause serious difficulties. If the rotary hammer is still under warranty, then with the question of lubricating its gearbox, it is best to contact a specialized workshop that provides warranty service for such equipment.

A detailed diagram of the device of your punch will help you understand the mechanism and correctly assemble the tool

If, however, the hammer drill that you own is not covered by any warranty or the warranty period for your equipment has already expired, and the Authorized Service Center is far enough away, you can lubricate the gearbox yourself, observing the maximum accuracy and care. To do this, you need:

  • A set of locksmith tools with which you will assemble and disassemble the perforator gearbox;
  • Clean rags;
  • The composition itself for performing lubrication.

“Native” grease for the Makita P-08361 reducer. Refills upon initial tool assembly and is recommended for maintenance

It is better if the lubricant is a proprietary product specially designed for equipment of a certain brand. So, it can be grease for a Makita rotary hammer or grease for a Bosch rotary hammer. If you have a branded lubricant, but you can’t buy it, you can also use inexpensive domestic lubricants.

It is very important that you have the instructions for the hammer drill, which you are going to Lubricate. Naturally, if you are the owner of a Makita or Bosch hammer drill, this should be an instruction manual for the equipment of these particular brands.

All parts of the gearbox must be completely cleaned of old grease

Having carefully studied the instructions for the perforator, you can start the procedure for lubricating its gearbox.

  • Before disassembling, the punch should be well cleaned of dust.
  • When disassembling the gearbox, it is advisable to immediately remember how the elements of its design are located in it. It should be borne in mind that it is not recommended to disassemble and lubricate the gearbox immediately after the end of using the hammer drill. This is explained by the fact that the still hot parts of the gearbox, if cold lubricating composition hits them, can lose their physical characteristics.
  • After all components of the gearbox have been removed from its housing, they should be thoroughly rinsed with gasoline or spindle oil and wiped dry.
  • The inside of the gearbox housing must also be washed, wiped (as far as possible) and allowed to dry completely.
  • When disassembling the rotary hammer gearbox, you can pay attention to the fact that there is no lubrication on some elements of its design. It only means that such parts do not need lubrication and applies it to them if necessary.
  • As mentioned above, it is better to use a proprietary lubricant for the gearbox of a drill or hammer drill, which has a number of advantages. In particular, branded lubricants retain their initial characteristics much longer, so they can be used much less frequently. In addition, the proprietary lubricant composition has such an important quality as water resistance, so it effectively protects the metal parts of the rock drill from moisture and, accordingly, from corrosion. As a good alternative to branded lubricants for a hammer drill or drill gearbox, you can use Metabo oil, the cost of which is quite affordable.
  • After lubrication of all elements, the gearbox must be carefully reassembled following the reverse sequence.

Before performing this procedure, the tool shank should be thoroughly cleaned. After that, a special grease for rock drill drills or regular lithol is usually applied. In addition, if an open-type cartridge is installed on perforators, it is advisable, after wiping, to process its oil seal, which will provide more reliable protection of the inside of the device from dust.

Brown Punch Lubrication

How to lubricate a punch

The punch must be lubricated strictly in accordance with the annotation:

  • Remove residues of dust and dirt;
  • Before disassembling the tool, remember the location of its parts;
  • Immediately after completion of work, it is forbidden to Lubricate, you need to wait a while. Otherwise, cold oil will provoke problems in the future due to contact with heated elements;
  • After removing the gearbox and brown, they are washed with gasoline and dried. It is better to purchase branded lubricants designed for specific models. The hammer drill will repel moisture. The risk of corrosion is minimized;
  • After completing the procedure, the parts are carefully assembled. With proper lubrication, the tool is completely ready for use.

Drill grease

Everything is exactly the same here. Special greases for this purpose are called so. For the Boers. And also themes are usually produced by the same firms that do punchers.

In the absence of a special lubricant, you can use graphite. But it does not remove heat from the shank so well, and this is important, since sometimes during prolonged work the shank sometimes becomes flattened, which is why it is difficult to extract it later.

What is hammer drill lubricant and what is it for?

Lubrication. It is a viscous substance designed to greatly reduce the coefficient of friction of boundaries between parts of the tool. Reduce, not remove one hundred percent. That is, this means that the friction of the boundaries by the parts is virtually constant, and at the same time some of the small particles are separated from the tool and get into the oil itself. After a while, this grease saturated with iron dust does NOT perform its specific function.

At first, its viscosity simply changes, and later the lubrication itself is a prerequisite for the rapid wear of the tool parts. Viscosity is considered the main parameter that you need to pay attention to when buying it.

The manufacturer indispensably shows in the technical documentation all the properties of the tool and the lubricating mass that must be used. Great attention must be paid to the frequency of maintenance, which indicates how long it takes to change the lubricant.

For a hammer drill, which has a certificate of properties, it is imperative to use only branded lubricants, in an unpleasant case, after the tool breaks down, you will lose the right to warranty service.

After the warranty period has passed, it is also better to use the lubricant recommended by the manufacturer, but at this time, most often, the user uses the cheapest domestic counterparts. Litol or grease will NOT harm your instrument in any way. But do not forget that lithol is produced even faster, that is, it must be replaced much more often.

How to lubricate a hammer drill gearbox

The perforator gearbox should be lubricated with a special material, which is called gear lubricant. Such a lubricant for a hammer drill gearbox is produced both under brands of well-known product brands and under common names, for example, Xado, Shell, Ravenul. What kind of hammer lubricant to use depends on the money. Special lubricants are much more effective than grease or Litol.

Usually, for each model of the product, the manufacturer specifies the recommended lubricant in the instructions. You can lubricate the perforator gearbox with your own hands, since the procedure is not particularly difficult and does not take much time. Replacing the gearbox lubricant at home requires disassembling the machine, so you need not only new lubricant, but also a screwdriver.

The sequence of lubricating the gearbox with disassembling the rock drill is as follows:

  • Before disassembling the product, it should be thoroughly cleaned of dirt and dust.
  • If the tool has been used recently, then you need to wait a few hours until it cools down.
  • After removing the cover of the punch body, a visual inspection should be performed. The lack of lubrication on the gears will indicate that prevention should be carried out much more often.
  • Remove all parts of the gearbox from the housing, and then thoroughly rinse them with kerosene or gasoline. After that, they need to be wiped dry. All retrievable elements must be remembered where and how they were located.
  • After that, you can begin to lubricate the structural elements of the gearbox. Some models of rock drills in the design of the gearbox have special containers for oil. The presence of such a container is indicated in the instructions, which also contains information on the location of the oil filling hatch. Initially, all elements are lubricated separately, and then the entire gearbox should be checked for the presence of grease, and where little. Add to.
  • Before installing the gearbox in place, it is necessary to wipe the housing with a dry cloth, thereby remove metal particles and dust.

What kind of lubricant for the gearbox to choose has already been discussed above. In any case, it is worth understanding that the more expensive the tool, the better the lubricant should be used. After installing the gearbox in place, you should assemble the tool and check its performance.

Equipment overheating reasons

In many home craftsmen, the question arises about how to use a hammer drill so that the housing of its gearbox does NOT overheat. First of all, you should find out the reason for the excessive heating. One of these reasons may be too much grease in the inner part of the gearbox, which also negatively affects the performance of the device.

The reason for the intensive heating of the perforator gearbox may be that an insufficient amount of lubricant is supplied to its internal parts. This can happen when the hammer drill is used for too long in slotting mode.

Through this hole in the punch body, lubricant is periodically added during operation

Another common cause of device overheating is clogged holes that supply cooling air to the hammer drill motor. In such cases, it is necessary to thoroughly clean the rotary hammer from dust and put it in the normal drilling mode for a while. When operating in this gentle mode for about half an hour, the temperature of the gearbox housing should decrease.
