You have a bearing problem if it is wobbling and possibly armature damage. You can go to ereplacementparts.com and look at a parts breakdown for disassembly. You can remove the cover to see if the bearing has collapsed. Let me know.

SOURCE: Bosch 11247 Hammer drill works

Usually replacing the o-rings on the piston, striker and Impact bolt will solve any hammering issues. That is considering there is no damage to the mechanical parts in the hammer mechanism.

SOURCE: i have a bosch rotary hammer 11245evs and it was

They are filled with a special grease that comes from Bosch. It sounds like the impact bolt or the striker pin in the unit are not moving the way they should. These are the pieces that work together to create the hitting action. About all that can be done now is the unit has to be dismantled to get those to pieces moving again. Bosch makes what they call service packs for all thier hammers. They have all the o-rings and grease to get your hammer working again. A Bosch service center can supply you with the kit. Ask for P/N 1617000225, or they can take care of it for you.
Hope this helps

SOURCE: rotary hammer won't rotate, hammers very good

If tool hammers brushes still good. Motor runs hammer action.
Take hammer/ drill switch lever off by removing small plastic plug in center with small screw driver.remove indicator handle off by removing #8 torx screw and lightly pry off. There is a pin and spring that lock tool into hammer or drill.Check for broken spring or binding spring and pin.If binding , clean and grease.

SOURCE: Bosch rotary hammer (model # 11230EVS) drill will not rotate

There is a clutch in the main spur wheel of the unit. These sometime begin to slip, on rare occasions they will slip to the point where the drill will not rotate. If you are interested the part number for this clutch is 1617000817.

SOURCE: Makita HP1640 hammer drill dual mode - 2 hours

Exchanged Makita HP1640 hammer drill for a new one. The 2nd drill did the same thing in under an hour!! Will return for refund. Instructions say the Forward/Reverse switch must be in a full up or down position for the Hammer/Rotary switch to move; well, it is and the Hammer/Rotary switch still stops at a 1/2 way point between modes. Although I can still use the drill, instruction warnings say not to because it may potentially burn out the motor. I'll have to go with a different brand this 3rd time around. It seems to be a design flaw.

Sparks coming off brush


#1 Check your brushes & brush springs - you will have to remove the switch handle completely to access both brushes
#2 Visual of the armature - is it black / burnt or does it have raised segments?
Most likely it will need an armature if it has run for any length of time with bad brushes.
The armature comes out the front of the motor housing so you need to remove the gearcase to access it. Armature 2610003331 for Bosch Power Tool eReplacement Parts Carbon Brush Set

I have a Bosh, model no. 11232 EVS Hammer Drill, but do not have the service manuel, and would like to know how to service it, how and when.


Many people service their hammer drill when it begins leaking, stops hammering, or just quits running. Bosch makes a service kit that comes with brushes, grease, and all the o-rings and seals their own technicians at the Factory Service Center use to rebuild the tool. 1617000263 is the part number for the service kit, and costs under 50.00 . The unit will have to be torn down and cleaned(everything forward of the armature). If you dont do it for a living, it can become quite a project. Try to avoid bringing into a service center disassembled, because they will charge you more than if you just dropped it off for a rebuild.

Exesive sparks on the brushes (Bosch GSB 16RE drill)


If you used the drill any amount with a burned field coil there is a good chance that is has burned the new armature out.
