Bosch gbh 2 24 dsr rotary hammer disassembly

Repairing a Bosch Peorator with your own hands

The rotary hammer is a construction tool for chiseling and drilling operations. Thanks to a special mechanism, the torch can punch a hole in different materials very effectively and quickly. It can be used to work with concrete, brick, metal, wood, stone. Bosch brand peorators are very common among builders and ordinary people, so it is very important to know how to repair these devices in case of breakage.

It is important to pay attention to the original models! There is a knockoff of the Bosch Hammer Drill chuck 32. Beware of imitations!

Bosch Peorator Disassembly

The electrical and mechanical parts are the main components of this tool.

  • motor;
  • The difference between the SDS-plus chucks and the SDS-max chucks is in the principle that the chucks have a motor control device (sometimes combined with a switch);
  • on/off switch;
  • The following are some of the components that damp out interference;
  • power cord.

This tool can be supplied with various accessories in the form of a drill, bits, vacuum cleaner and other parts.

Disassembly procedure for the Bosch 2-26 torch

Since the order of disassembly of the Bosch 2-20; 2-24; 2-26 is almost identical, let us examine the disassembly sequence on the example of the Bosch 2-26.

Disassembling the Bosch GBH 2-26 dre starts with taking apart the quick-release chuck.

Disassembling the quick-release chuck

The two most common types of chucks used in Bosch rotary motors are SDS-plus chucks and SDS-max chucks. The difference between them is the principle of clamping the tail part of the working organ.

The Bosch Peorator chuck design differs in the design of the tool’s seat rods, depending on the SDS-plus or SDS-max model. In addition to the above types of chucks there are SDS-top, SDS-quick chucks.

The difference between the cartridge mounting assemblies

The disassembly procedure for the Bosch 2-26 chuck is simple:

  • remove the rubber nipple pos.34;
  • take out the retaining ring pos.87;
  • Remove the steel washer pos.833;
  • Remove the conical spring pos.833;
  • carefully, so as not to lose it, using a magnet, take out the barrel balls pos.89.

Carefully examine all the parts of the cartridge.

SDS-plus quick-release chuck disassembled

SDS-plus chucks specially developed for drilling tools. Tool shank diameter is 10 mm, working tool length is in the range of 1101000 mm. Diameter of drills is in the range of 426 mm.

How to remove the mode switch

With the tool on its side, remove the mode selector pos.832.

First, turn the switch to the “Drill” position, press the screwdriver all the way into the face of the switch button (it’s red) and turn the switch counterclockwise at an angle of 70º.

Wiggle the switch handle and pull the switch handle out of the.

Disassembly of the firing mechanism assembly

With the Bosch 2-26 upright on the handle, remove the four screws from the.90 holding the housing cover of the mechanical assembly.

Next press on the end of the striker shaft and remove the cover. Black plastic cover.

Now remove the barrel, pos.821 and the intermediate shaft pos.826. They are not secured in any way.

Then using a screwdriver remove the shackle, pos.48 rolling bearing pos.830. By the way, in simple terms it is called the “drunken bearing”. removed one by one: sleeve, pos.26 and the “drunken bearing”.

Got to the drunken bearing

bosch, rotary, hammer, disassembly

Disassembly of the cylinder

There is a striker inside the cylinder pos.27, from which you must remove the rubber ring pos.73. Rubber parts must be replaced at any disassembly.

On the opposite end of the cylinder there is a pivot pos.29 and two flat washers pos.41.

Disassembling the intermediate shaft

The intermediate shaft is disassembled by removing the shaft pos.24 and pulling it out of the housing pos.77 “Drunken bearing”.

Bearings can be removed with pullers or by hand, with the help of a tool.

An unusual problem with a Bosch torch

Bosch pedal motors are very reliable. But there are faults that are almost never seen in practice. Here is one of these.

Bosch drills but doesn’t chisel

If your torch stops chiseling but lets you drill, the most likely cause is a broken “Drunk Bearing”. This fault is not very common and can be difficult to find.

No need to go to the garage to fix it. Anyone with a little mechanical understanding can do it.

New Drunk Bearing

First disassemble the Bosch torque motor as far as the intermediate shaft. The disassembly procedure is shown above.

By removing the intermediate shaft you get to the “drunk bearing”. A broken roller bearing is indicated by a broken cage, scattered balls, and pieces of the cage.

Take out the bearing, remove dirt, all parts of the broken mechanism.

Buy a new “drunken bearing”, and, having lubricated all parts with new grease, replace and reassemble, in the sequence opposite to the steps of disassembly.

Brush replacement

If the time has come in the peorator to change the brushes, for this task you can take the tool to a service center, or you can carry out your own hands, which is not difficult. Service center replacement has a number of advantages:

  • Quality work if it is a specialized center
  • Original parts, for your tool model
  • Extended warranty, if it’s not already expired
  • In addition to replacing the broken part, the service usually inspects all internal important parts, cleans them, and lubricates them

Along with the advantages, power tool repair in the service center also has negative aspects:

If you are not satisfied with the mentioned inconveniences of repairing the tool in a specialized center, it is better to perform the task yourself.

The parts replacement process is done in stages:

  • When unplugged, unscrew the peorator to remove the top cover.
  • After that, use a small screwdriver to easily hook the brush holder, pull it out and remove the old parts.
  • Insert the new ones into the holder, press them to the edges, install them in place inside the peorator.
  • Make sure the brushes reach the contacts for smooth operation of the power tool.
  • Close the cover and secure it with screws.

Handyman’s tips for repairing the torch

When performing the replacement of brushes on their own, experts recommend:

  • If one is wiped out, both should be replaced
  • At the same time you should clean dust and carbon deposits from the collector during the repair
  • When replacing the part, it is better to lapping it to the collector with fine sandpaper
  • It is better to use components that comply with the model of the tool

Replacing the brushes is a simple process that can easily be done at home.

The torch is your assistant in all kinds of repair work. As unfortunate as it may sound, as well as what to do our client here is the sun, it also does not work forever. At some point you have to deal with its maintenance not repair. The more care you take with it, the longer it will last.

Nettle, your peorator has lost power. It says it all? Repair work is pending or “it’s time to go”? Mostly something special, I guess. it’s just time to change the brushes in the torch.

Brush. part of the electrical circuit of the electric motor, the current conductor to the collector armature. Since the armature rotates, due to the electromagnetic field, there can be no fixed connection as in the stator. The way out was realized by using pieces of graphite, which slides over the collector plates, thereby supplying current to the sectioned armature winding. In turn, in the winding of the latter creates a magnetic field. According to the law of magnetism, the opposite poles are attracted and this creates the motion of the armature. As pictured below.

But we can say that this is the weakest place of collector motors, because brushes in the process of work are erased, and coal dust clogs collector. this leads to a violation of the normal operation of the electric motor.

The construction of a brush is very simple: the contact terminal, the wire from the terminal to the working surface of the brush, and the spring that presses the surface to the collector plate.

We have understood the purpose of brushes, now let’s look at their types. There are three types of brushes. How to change the cartridge on a peorator There are actually more. but they are not used in peorators. For example, the so-called “generator” (copper-graphite, copper. carbon) brushes.

In peorator you can find brushes of these types:

  • Graphite. long life, but due to the hardness of the graphite, the “lapping” is not ideal, and the collector suffers from this;
  • Carbon brushes for the gator. good contact with the working surface of the manifold, but short service life;
  • carbon-graphite brushes as an alternative to the previous two types.

Design features of the Bosch 2-24

The best way to repair your Bosch 2-24 is to familiarize yourself with the schematic diagram and the constructional features of the tool you are installing. The principle of operation of the Bosch 2-24 is similar to that of the Bosch 2-20.

The torque is transmitted to the tool mount shaft, simultaneously with the transfer of the shock impulse. There are three modes of operation for the burner: drilling with impact, drilling without impact, impact.

Rotor helical gear pos.803 transmits torque to the helical gear of the intermediate shaft pos.826.

schematic diagram of the Bosch 2-24 accelerator

Intermediate shaft design of the Bosch 2-24 torch

The intermediate shaft of the Bosch 2-24 geared motor consists of a roller bearing unit pos.830, clutch parts pos.823, shift parts pos.44. Failure of the clutch is the most common failure. The teeth in the clutch are wearing down. Repair of the clutch is to correct the tooth profile in the clutch and on the intermediate shaft.

Intermediate shaft assembly Bosch 2-24

Shaft design of the percussion unit

The shaft of the firing unit is designed to transmit the rotary impulse and to move the firing pin at the same time.

The rotation is transmitted from the spur gear of the intermediate shaft to the large spur gear pos.22 Barrel shaft pos.821.

The reciprocating motion is transmitted via the drunken bearing pos.830, percussion piston pos.26, hammer pos.27, striker bolt pos.28 on the chuck mounted pos.756 drill.

Design is a shaft, hollow on one side. Components are mounted on both sides of the shaft.

On the side where the chuck is mounted, a spur gear pos.22 and is fixed on the shaft by a roller pos.88, is pressed against the shoulder of the shaft by the spring pos.80. The spring itself is secured by a retaining ring pos.85.

In the cavity of the shaft of the firing unit is inserted: assembled firing pin pos.28 and the striker piston. In the striking piston pos.26 the striker pos.27 with a new rubber ring pos.73. Lubricate all rubber parts with recommended grease.

Failure of the striker shaft

Due to weakening of the spring force, fixing roller drop out, the pinion may rotate on the shaft. This manifests itself in the loss of torque with the presence of a shock pulse.

Drill but not punch.

When the rubber-mechanical elements (O-rings) are worn out, the motor ceases to operate in the “Boring” mode. This occurs gradually. The striking force becomes weaker as the rubber rings wear. The whole point is that from the drunken bearing, the motion is transferred to the impact piston pos.26 in which the striker pos.27 generates air pressure and acts on the striker bolt pos.28.

Drills but not chisels.

If you apply too much force when operating the tool it may result in the firing pin failure, jamming of the striker in the striker piston and other damage. This condition can be eliminated only by the full replacement of the damaged part. details about troubleshooting in the Bosch perforator.

Design features of the Bosch 2-26 torch

To begin the repair of the Bosch 2-26 torch you need to know the construction of the tool you are installing. The principle of operation of the Bosch 2-24 is similar to that of the Bosch 2-26.

Schematic diagram of the Bosch 2-26

rotation is transmitted from the rotor shaft, through the intermediate shaft, to the striker shaft. Drunken bearing fixed to the intermediate shaft at the same time transmits the reciprocating motion to the striker piston.

There are three operating modes of the rotary table: drilling with impact, drilling without impact, impact.

Rotor helical pinion pos.803 transmits torque to the helical gear of the intermediate shaft pos.823.

The intermediate shaft is similar to the shaft in the construction of the Bosch 2-24 and is interchangeable with the parts included in the intermediate shaft of the Bosch 2-24, 2-26. Instructions for disassembling the Bosch perforator.

Failure of the shaft of the striker unit

The design of the firing unit barrel shaft is similar to that of the Bosch 2-24 torch unit. Failures are caused by the same parts as in the Bosch 2-24.

Shaft diagram of the striker shaft

The Bosch 2-26 shaft is characterized by a large spur gear pos.22 is secured to the shaft by three pins pos.37, unlike the fixing roller in the Bosch 2-26 torque converter.

When disassembling the firing pin shaft of the Bosch 2-26 firing pin, pay attention to how the pinion is locked in place. Before removing the gear, you have to remove the three pins. Order of the correct assembly of the Bosch rotor.

Disassembling the electrical part of the Bosch 2-26

Disassembly of the Bosch 2-26, its electronic part, begins with the removal of the back cover on the handle of the rotor by removing the three screws.

Then pull out the reversing switch.

Turn it into neutral position without lifting it personally. Pull out the reversing switch.

To remove the stator cover, you must clasp the mechanical assembly in your right hand and the stator housing in your left hand and drag them in different directions while wiggling.

Separating the percussion unit from the rotor not the stator

To separate the rotor from the mechanical assembly, it is sufficient to drag these parts in different directions. The rotor is fitted to the mechanical unit by a small helical gear inserted into contact with the large helical gear of the mechanical unit.

You can not look closely at the condition of the collector, the bearings.

What to remove the stator, rather remove the protective plastic protective sleeve, do not knock with a wooden spindle on another saying cudgel at the end of the body, in which the stator is inserted. Before this is still necessary to keep in mind to remove the two screws that secure the stator in the housing.

the stator is removed, the rotor is taken out, naturally proceed to their inspection not the defects of all parts that are part of the electronic part of the Bosch rotor.

When examining the disassembled Bosch 2-26 burner, pay special attention to the condition of the carbon brushes, deposits on the brush holders, the integrity of the reversing switch contacts, the condition of the wire at the entrance to the burner.

The length of the brushes can not be shorter than 8 mm. On the brush holders do not need to make a spark and carbon dust from the brushes on the contacts of the reversing switch is not Bosch 2-26 burnout or otherwise damage contacts.

Depending on the power tool is suitable for household and professional needs. The peorator is a functional building tool. The device consists of an electronic motor and gearbox, an impact unit and a cartridge under the nozzle. On the outside there are handles and []

The most widespread among professional builders in Russia are the Bosch peorators, and among amateurs the household models Bosch 2-20, 2-24, 2-26.

Peorators not only work well, they are also easy to repair. Any defective part can be easily found.

The designs of the described perforators are based on the same principle, to transmit the torque from the rotor to the shaft of the percussion unit while at the same time transmitting the progressive impulse to the working tool.

Structurally, the torches are made under the same scheme, but individual units or parts have their own features.

If you know the specific differences between the models of the described Bosch torches, disassembly and repair with your own hands will not be difficult.

Along with the originals on the Russian market there is a large number of fake tools, including Bosch torches.

The design features of the models and ways to disassemble and repair them with your own hands are described below.

Bosch torch principle of operation

The principle of operation of the peorators is the same, but the design features are different.

Main details, used in the listed models of Bosch perforators, are interchangeable. This applies to the mechanical and electrical assembly.

But there are nodes that differ in the parts used.

To repair a Bosch 2-20, 2-24, 2-26, you need to know these differences. Knowing the design features of each torch makes it easier to repair it and find and repair the defects.

Designs of Bosch torches are so simple that they allow making simple repair practically by your own hands and replacing any part without service call. It is necessary to have skills of assembler, to have elementary knowledge of electricity and understand the principle of perotor.

Design features of the Bosch 2-26 torch

To repair the Bosch 2-26 you have to get acquainted with the construction of the tool to be adjusted. The principle of operation of the Bosch 2-24 is similar to that of the Bosch 2-26.

The rotation is transmitted from the rotor shaft, through the intermediate shaft, to the shaft of the percussion barrel. Drunken bearing fixed on the intermediate shaft transmits reciprocating motion to the striking piston.

Three operating modes on the rotary table: drilling with impact, drilling without impact, impact.

Helical rotor pinion pos.803 transmits torque to stub shaft helical gear pos.823.

The intermediate shaft is similar to the shaft of the Bosch 2-24 penorator and is interchangeable with the parts included in the intermediate shaft of the Bosch 2-24, 2-26 penorators. Instructions for dismantling the Bosch torch.

Shaft design of the striker shaft

The design of the firing pin shaft is the same as that of the Bosch 2-24 torch shaft. Failures are caused by the same parts as in the Bosch 2-24.

A special feature of the Bosch 2-26 shaft is that the driven large spur gear poses.22 is fixed on the shaft by three pins pos.37, unlike the securing roller in the Bosch 2-26 peorator.

When disassembling the shaft of the Bosch 2-26 drum unit, pay attention to how the pinion is fixed. Before removing the pinion it is necessary to remove the three pins. How to Reassemble Bosch Pellets Properly.

Disassemble the peorator and remove the cartridge

In order to repair the peorator, you must first properly disassemble it. And we begin by disassembling the cartridge.

  • Remove the rubber tip and retaining ring;
  • Remove the washer and conical spring;
  • Take out the side balls (preferably with a magnet);
  • Place the mode lever in the position equal to the maximum and remove the switch knob. Fix the position;
  • Remove the back cover on the handle and motor brush;
  • Unscrew the 4 screws near the auger to remove the front cover;
  • Remove the barrel and shaft, and using a screwdriver, remove the bracket and bearing;
  • Open the back cover and take out the reversing switch;
  • We remove the rotor, for which we unscrew the fasteners and disconnect the terminals from the starter, which must also be removed by removing the protective cover.

Important! When disassembling, be extremely careful where and when you remove any parts. Fold them so that they are not lost in any way. Whether or not you can put the tool back together again depends on this.

Bosch Peorator Repair with your own hands

If any parts in the tool are damaged, broken or not properly functioning, they simply need to be replaced. If the brushes are frayed, they are simply replaced with new ones during disassembly. Peorator cartridge in slow rotation of the rim, worn dust cap, failed bearings are also replaced. But there are other malfunctions you can fix as well. If a winding breakdown occurs, the stator and armature must be rewound. Keep an eye on the lubrication and lubricate some parts from time to time.

Bosch Peorator Repair 2 26

Before fixing anything in this model, you should get acquainted with the features of the device, the circuit and the principle of operation. The rotor shaft transmits the rotation to the shaft of the barrel through an intermediate shaft, the bearing of which directs the return motion to the striking piston.

When disassembling the barrel shaft in the firing unit, pay special attention to the fixation of the spur gear. Before you remove it, you must remove the 3 pins holding it in place.

Repair of Bosch 2 24 Peorators

In this Bosch gbh 2 24 dsr peorator, the intermediate shaft consists of a shift part, a bearing assembly and a clutch. The latter deteriorates most often, because in it the teeth wear out quickly. Repair of this breakage is to correct the tooth profile of the meshing. You often notice that there is no shock. The motor may gradually stop chiseling due to the wear of the rubber parts, which must be replaced in time. And if you apply more than necessary power, it can lead to the fact that the striker piston jams the firing pin.

Repair of Bosch 2-28 torches

Sometimes slots in this tool model are subject to wear. In this case, you need to disassemble the reducer (it is almost similar to Bosch 2-24, only the bearing is different). It is better to replace the entire trunk, because together with the slits wear out and the strikers.

As you can see, the repair of peoratorov can do at home with their own hands. At the same time not to spend a lot of money on various types of repairs in the service centers, which, as we know, are very expensive. But do not forget that it is necessary to adhere to the rules of use and safety.
