Question about Bosch Drills

1 Answer

I have a bosch hammer 11311EVS I bought it used and on first job gave out on me. Everybody said replace the brushes so after a repair get was bought . I replaced them I checked and still no go . So I got a light checker and checked the cord it was good. I checked the on and off switch it was good. I got to the governor #80 on item list. and power going in from on off switch was good holding a steady light when i checked power coming out of governor the light checker was blinking not holding the steady light from before . The thing is the light on the governor wicth is suppose to turn on if it fails is not on when i pluged it so do i need a new governor what do i need to do to keep checking it to figure the problem out ?

I would take it to a Bosch service center at this point. You could end up spending a fair amount of money putting parts in until you get the unit to work. Problem with the governors is they are hard to meter, you almost have to have a fresh one to put in a try. If you have gone through everything up to the governor you will have to start looking at the field coil or armature. Let a service center tell you whats wrong so it costs you less money and time.

I have a bosch 11264EVS hammer drill that just stopped working. I checked the brushes and have continuity to the rotor. Is there somethingelse I need to check/replace before I hunt sown a service center?

Did you have continuity from one brush to the other? Some Bosch tools use "pop off" type of brushes. When they get worn down a spring loaded center pops out and keeps you from damaging the armature. If they are fine check cord continuity. If the cord is fine it is most likely the switch. You can test the field for continuity also but those rarely ever fail. Here is the parts diagram.

could be quite a few things, check the cord for a break that might have shorted the outlet. Also this tool requires 20 amp service so it could have affected the brushes, switch or other major electrical parts. Unless you are mechanically inclined and have a volt ohms meter I would suggest taking for repair.

I bought a used Bosch Bulldog hammer drill on the internet some time ago and discovered it's not hammering. It will drill be almost no hammer action. Any suggestions?

There is an o-ring on the striker that will wear down over time, this needs to be changed, of worst case the striker has stuck in the hammer piston. Both these repairs should really be done by a service center as these hammer drills are complicated to repair if you are not familiar with them. Any Bosch service center will be able to help you. Just go to the Bosch website and find a center in your area.

Check the motor brushes for breakage, badly worn, or weak springs (heat damage). Keep track of brush wear pattern when removing and reinstall in the same orientation.

Hammer drill quit

If it is an 1199, forget it. Replace the brushes and do NOT use for hammering. It is a design problem. My unit was repaired 4 times and hammered about 5 holes each time before same failure.

Drill just stopped? not working

These tear the brushes out. You can not use them for hammering. It is a design problem.

Replace the brushes and use only for straight drilling.
