I order parts for my Bosch tools at WWW.toolpartsdirect.com. They have the parts lists also so it is easy to find what you need. Don't forget to order some bosch grease for your tool because you will need to carefully wash-out all the old grease with metal bits. Good luck with you repair. Enjoy

Have you pulled the collar to release the pressure on the steel balls. Just pull the collar usually forward and slide on the shaft and then release and twist till it locks. Let me know if I can help further

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.

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

The spindle still spins, even in hammer mode. This model will jump out of hammer mode, sometimes you will have to duct tape it in position hammer.
