Repair of the cartridge of the BOSCH oral transplant: how to correctly disassemble and repair the Bosch peorator with your own hands

The principle of operation of the Bosch 2-26 peorator does not differ from the peorators of well-known brands.The rotating rotor transfers torque to the intermediate shaft of the mechanical node of the penetrator, while transmitting the progressive movement through the rolling bearing to the perch mechanism of the ash and the impact pulse. A rotational moment is transmitted to the working tool with a progressive shock impulse. This principle is implemented in all peorators.

But various companies producing peorators have their own design features.

Bosch peorators are considered the best in their segment of power tools. But there is nothing eternal.

If your Bosch 2-20, 2-24, 2-26 pea has stopped working, then it can be restored with your own hands. You need to have elementary locksmith skills and understand a little in electrical engineering.And also an important detail, the design of Bosch peorators is so simple that it does not cause difficulties in repairing.

When repairing power tools, including Bosch peorators repair, strictly observe safety precautions when working with electrical appliances.

To facilitate the repair of the Bosch peorator, its disassembly and assembly, study the instrument assembly scheme:

Any disassembly of the Bosch 2-26 pedorator begins after inspection, testing and identifying the causes of the device malfunction.

The procedure for disassembling the Bosch 2-26 peorator

Since the procedure for disassembling the Bosch 2-20 peorators; 2-24; 2-26 is almost the same, consider the sequence of disassembly on the example of the Bosch 2-26 peorator.

Disassembling the Bosch GBH 2-26 DRE ONE begins with disassembling the fast-parting cartridge.

Dismantling of a quick.Parting cartridge

In Bosch peorators, two types of cartridges are most often used: SDS-Plus cartridges and SDS-MAX cartridges. The difference between them in the principle of the clamp of the tail of a working organ.

The device of the BOSCH pedorator cartridge is different in the design of the boiler rods depending on the SDS-Plus or SDS-MAX model. In addition to the listed types of cartridges, SDS-Top, SDS-Quick cartridges are found.

The difference between cartridges attachment nodes

The procedure for disassembling the infantry cartridge Bosch 2-26 is simple:

  • Remove the rubber tip pos.34;
  • Get out the stop ring pos.87;
  • Remove the steel puck pos.833;
  • Draw a conical spring pos.833;
  • Gently, so as not to lose, using the magnet, take out the barrel balls pos.89.

Carefully inspect all the details of the cartridge.

Uncharacteristic malfunction of the Bosch Peorator

Bosch peorators are very reliable. But there are malfunctions that are practically not found in practice. Below is one of them.

The Bosch peorator is drilling, but does not hammer

If the peorator stopped hammering, but at the same time allows you to drill, the most likely cause may be the destruction of a “drunk bearing”. This malfunction is not often found and it is not easy to find it.

You do not have to go to the repair workshop to eliminate it. Such a malfunction will eliminate any person who is more or less versed in mechanics.

First you need to disassemble the Bosch peorator to the intermediate shaft. The disassembly procedure is given above.

Having removed the intermediate shaft, you will get to the “drunk bearing”. The destruction of the rolling bearing is indicated by a broken clip, scattered balls, pieces of clips.

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

Buy a new “drunk bearing”, and, lubricating all the details with a new grease, replace and assembly, in the sequence, reverse steps of disassembly.

Dismantling the electric part of the Bosch 2-26 infantry

Dismantling of the Bosch 2-26 peorator, its electric part, begins with the removal of the rear cover on the pen of the penetrator, twisting three screws.

At the next stage, it is necessary to remove the reverse switch.

Turn it into a neutral position and raise it on yourself. The reverse switch is taken out.

To remove the stator lid, holding a mechanical knot in the right hand, and drag them into different directions into the left hand of the stator, shaking them.

Separation of a shock block with a rotor and stator

To separate the rotor from the mechanical node, it is enough to drag these parts in different directions. The rotor is mounted in a mechanical node with a small lobby gear, inserted into contact with a large lobby of the gears of a mechanical node.

The rotor was released and you can carefully inspect the condition of the collector, bearings.

Repair of Bosch Peorators and its features

A peoporator is a construction tool with which they perform dialled and drilling operations. Thanks to a special mechanism, the peorator is very efficient and quickly pierces the hole in different materials. It can be used in 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 their breakdown.

It is important to pay attention to the original models! There is a fake the Bosch Hammer Drill 32. Beware of fakes!

  • With a horizontal installation of the engine (the barrel and the anchor of the engine are placed in parallel);
  • With a vertical installation of the engine (the same parts are at a right angle).

Electric and mechanical parts. The main components of this tool.

  • Engine;
  • Engine control device (sometimes combined with a switch);
  • Switch/switch;
  • Elements that are hidden;
  • Network cord.

Different additions in the form of a drill, crowns, a vacuum cleaner and other details can be attached to this device.

Disassembly of the penetrator and removal of the cartridge

To repair the peorator, first you need to correctly disassemble it. And we begin to do this with a disassembly of the cartridge.

  • Remove the rubber tip and stop ring;
  • We extract a puck and a conical spring;
  • We take out the side balls (preferably using a magnet);
  • Put the lever of operating modes in a position equal to the maximum maximum, and remove the switch handle. Fix the situation;
  • Remove the rear pad on the handle and engine brush;
  • We unscrew 4 screws near the drill to remove the front cover;
  • We take out the barrel and the shaft, and with the help of the screwdriver. A bracket and a bearing;
  • Open the back cover and take out the reverse switch;
  • Remove the rotor, for which we unscrew the strengths and disconnect the terminals from the starter, which also needs to be removed by extracting a protective casing.

Important! When disassembling, be extremely attentive to where and when you extract certain details. Fold them so that in no case do not lose. It depends on this whether you fold the tool back or not.

Do.It.Yourself

If some details in the tool are damaged, broke or poorly perform their function, then they just need to be replaced. If the brushes are and, then during analysis they are simply replaced with new. The cartridge of the penetrator during slowed rotation of the rim, worn an boiler, the failed bearings are also replaced. But there are other malfunctions that you are able to fix. If the winding break occurs, then you need to rewind the stator and anchor. You need to monitor the lubricant and from time to time lubricate some parts.

Repair of Peorators Bosch 2 26

Before correcting something in this model, you need to familiarize yourself with the characteristics of the device, the scheme and the principle of action. The rotary shaft transfers rotation to the shaft of the barrel through the intermediate shaft, the bearing of which directs the return movement to the stressed piston.

When disassembling the barrel in the shock block, you need to pay special attention to the fixation of the straight.Line gear. Before you remove it, it is necessary to remove 3 pin on which it is fixed in this model.

Repair of Peorators Bosch 2 24

In this Bosch GBH 2 24 DSR, the intermediate shaft consists of a switching part, a bearing node and clutch couplings. The latter spoils most often, because the teeth wear out quickly in it. Repair of this breakdown is to correct the profile of the gear tooths. You can often notice that there is no blow. The peorator may gradually stop hammering due to wear of rubber parts that need to be replaced in time. And if you use more than you need strength, it can lead to the fact that in the shock piston it will jam the boiler.

Repair of Peorators Bosch 2-28

In this model of the tool, slots sometimes wear out. In this case, it is necessary to disassemble the gearbox (it is almost similar to Bosch 2-24, only the bearing differs). It is better to replace the entire barrel, because together with the slots we wear out.

Diagnostics of the penetrator

Take the multimeter, switch it to the continuity mode and start testing using the power cord.

  • Connect one probe to the end of the fork, and the other to the contacts on the other end of the wire. When connecting to one of the contacts, the sound signal should be heard. Do the same with the other end of the fork.
  • Check the power button on the power cable and stator contacts. Pull the trigger.
  • Check reverse contacts.
  • Connect the measuring wires to the brushes to check the contact through the anchor.
  • Connect the probes to the stator wires and make them ring.
  • If the contacts of the stator or brush do not call, and the buttons and the power cord are serviceable, then proceed to the diagnosis of collector and engine windings.

Diagnosis of wires and buttons of a multimeter as a multimeter

At the anchor, first inspect the collector and winding. If the wiring is melted, the burnt insulation paint will leave black traces or a specific smell. You can see curved and crumpled coils or conductive particles, for example, the remnants of the solder. These particles cause a short circuit between turns. Collector damage: raised, worn or charred plates.

We put the resistance of 200 Ohms. Connect measuring probes to two neighboring collector plates. If the resistance between all neighboring plates is the same, the winding is in good condition. If the resistance is less than 1 Ohm and very close to zero, there is a short circuit between the turns. If the resistance is two or more higher than the average, there is a break in the turns of the winding. Иногда при выходе из строя сопротивление настолько велико, что устройство зашкаливает. On the analog multimeter, the shooter will go to the right to the right. And on the digital he will not show anything;

Determination of innovation. Set the maximum resistance on the scale of the device. Depending on the tester, it can be from 2 MOM to 200 MOM. Connect one probe to the rod, and the other. To each plate in turn. In the absence of malfunctions, the resistance should be zero;

Do the same with the rotor. Connect one probe to the iron corps of the rotor, and draw the other on the plates.

Determination of the closing of the winding of the rotor body

An anchor can be saved if you do not break the balance. If during operation of the device an intermittent hum appears and strong vibration is observed, this is a violation of the balance. This anchor must be replaced. And you can repair the winding and collector. Small short circuits are excluded. If a significant part of the winding is damaged, it can be rewound. Grind worn and severely damaged lamellas, accumulate or weld. Also, do not take on the repair of the anchor if you are not confident in your abilities. It is best to replace it or take it to the workshop for repair.

correctly, disassemble, bosch, pull, drill, perforator

Set the resistance mode for 200 Ohms. Connect the probes of the device to the ends of the winding. One means a cliff, and zero means a short circuit between turns. If the resistance exceeds 1.5 Ohms, check the second winding. Both windings must have approximately the same resistance;

Check the lack of circuit to the ground, that of a short circuit of the winding on the metal case of the stator. Set the multimeter in maximum resistance mode. Connect one probe by the end of the winding, the other to the metal body of the stator. The device does not show faults.

Bosch 2-20 transit and design scheme and design

Repair of the Bosch 2-20 peorator will not be possible without knowledge of the design of a fixed tool.

The principle of operation of the Bosch 2-20 peorator is based on the transfer of the rotational moment from the shaft of the Rotor pos.3 to the shaft of the shock block pos.22 through the intermediate shaft pos.824, simultaneously transmitting a longitudinal pulse to a working tool.

Rotor pos.3 transfers a rotational moment to the gear of a shock.Absorbing intermediate shaft pos.824.

The scanty gear is fixed on the intermediate shaft and transfers the moment of rotation to the shaft. A drunken bearing is fixed on the shaft, receiving the moment of rotation through the clutch coupling. Due to its design, a drunken bearing transfers progressive movement to the cylinder of the stress mechanism barrel.

The design of the intermediate shaft of the Bosch 2-20

The intermediate shaft of the Bosch 2-20 peorator consists of a rolling bearing node (drunk bearing), clutch couplings, a large lobby gear, and a small straight line of a cylindrical gear.

Most often, breakdowns are manifested in the wear of the clutch huts, which leads to the disappearance of the rotation of the infantry cartridge in the presence of a shock pulse.

Corrected by the replacement of the clutch coupling or the restoration of the teeth of the coupling parts.
