Questions & Answers

Excessive spark from the motor.
Jose for model number 11304 asked on 2019-11-14
Hi Jose, Thank you for your question. If the motor is sparking, this can be caused by a motor overload, vibrations, high humidity, worn brushes or worn commutators. When checking for sparking or arcing, you will need to inspect both the commutator and brushes to verify what the problem is. I hope this helps. Thank you and have a great day!
Runs with sparks and very little hammer action
Tim for model number 611304034 asked on 2020-02-25
Hi Tim and thank you for writing This is normally caused by worn brushes. Remove the brushes and inspect them for wear. Brushes 1/8 of an inch or less are considered worn and require replacement. Also, any uneven wear and any damage to the brushes such as chips and cracks will also require replacement. The communtator may also need to be cleaned at this time. You will have to remove the armature and clean it with electrical contact cleaner only. Inspect the armature for burn marks and melted insulation indicating it is bad and requires replacements. If it all passes inspection, use 600 grit aluminum oxide sandpaper only and wrap it around the communtator and rotate in the direction of travel only. Clean again with electrical contact cleaner and wipe dry and reassemble. Good luck with your repair.

Question: Bosch 11304-no Data Tag-034 Or 1...

TedGeneralRental

As the title line says...I am trying to identify my hammer without a data tag. I need a service pack, but don't know which one it is.
WJA
Hello TedGeneralRental,

The motor assembly between the 034 and 139 is one of the main differences, but that is a little difficult to tell without disassembling the tool. There is one difference on the outside of the tool which will tell them apart though. It is the guide tube ( item #37 on both the part diagrams). By looking at both diagrams you will be able see the differences, and hopefully identify your hammer.

Hope this helps,
WJA
HeyTedGeneralRental,

The outside of the piston housing on the 139 has very deep ridges while the 134 is smooth just like the drawings show. Hope this with WJA's explanation helps.
Question: Bosch 11304 Braker Repair

dieselMEN

I have a bosch 11304 Hammer. it seems to have lost its punch the motor and piston rod seen to work fine. I looked at the striker and piston there is no visible damage. although there is Grease every where. what give the striker power? is the grease supposed to be behind the striker in the cylinder? is the grease causing a suction, not allowing the striker to move freely?

thanks for any info
Mark
Mark, The piston causes high pressure in the cylinder forcing a slug down the cylinder which hit the striker pin which hits the bit.The striker pin has two o-rings and moves back and forth in short strokes.This most likely where your problem lies.You have grease leaking from the transfer case and this is why it coming out the link removed a service kit and replace the grease but don't replace the striker o-rings unless their damaged as replacement o-rings will have to go through a break in run of a couple of hours to get the hammer action working good. Hope this helps.
Thanks for your response, I have ordered the service kit and I am uncertain to where to put the grease. I currently have grease in the motor housing, (connecting rod area) the hammer piston (inside and out) and the Guide tube. I will clean the old grease out as best as possible.
What is the procedure for replacing the new grease?
Do I just squeeze the content of the tube in the motor housing (connecting rod area) and reassemble?

Is the o-ring you say not to replace #32 of the internal flange?

Any help will is appreciated
Thanks
Mark
Hi Mark.No you don't want to replace # 1610210033 ref #27. and yes you put the grease in the crankcase where the connecting rod is.the kit I believe gives you instructions on most of that. Hope that helps.
