This is the 5th tile project we've done where we've removed the old tile before installing new tile, and the first one with this tool ruclips.net/user/postUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS . I want to cry for all the unnecessary work we've done in the past. With this tool, we removed tile surrounding a fireplace, as well as the hearth tile, set in loads of cement, in less than an hour. I highly recommend this tool. It was easy to use, and very satisfying watching the tile literally fall off the wall.
bcbloc02 I dont think you could get down inside to make the solder joint work, the contacts are below the brush holders in the main body of the drill. I might be wrong, but I have never dug any deeper into this tool.
Bosch have used this same brush system for about 30 years, and it always used to be reliable, i can only assume 1 or 2 things, either the higher power motors draw too much power and burn them more (stress the metal?) , and poorer quality metal of the connectors/brush holder than used to be the case
Many thanks for this! I located the spade connectors on a similar type Bosch drill and tried first pulling them out and just pushing them in again. Plugged the drill into the power and it fired up perfect. I'm delighted!! Thanks again!!
Good video Stan. One thing I always do is coat the contacts with a silicone grease. Dow compound 4 or 11. 11 is thicker. Make these types of repairs last longer.
Hi Stan, I've got the much bigger brother of this hammer drill, with the SdS Max end, no problem after more than ten years, but the day it gives me problems, this video might save me time and aggravations... Thanks for sharing this... Pierre
Awesome! Thank you for making the video! We have four of these exact drills all with the same issue. We took them to be repaired and was told they were no good. I just went through and followed what you did and now I have four running drills. Saved me from having to buy more! Again Thank You!
I use that same exasperated tone when *I* say: "and with my *third* hand..." My wife looked in while I was watching the video, thinking that it was me talking! ;^) Thing is, to get my chemistry degree, I had to grow a third hand back in the day! ;^) Unfortunately, that hand is only really useful for working a wet bench in a lab... When it comes to machine design, I've never met that mythical "constant" pressure slip connector - any kind of a spring doesn't stand up well to heat and vibration... all you can do is hope that you get enough life out of the machine to not feel sad about junking it when metal fatigue and/or arcing kills your last available replacement part... All the Best, Eric
I have the 11241evs. And no hammer. I've ordered a service kit, my question is, are you supposed to oil these things somewhere periodically, besides keeping the grease up? I bought a enrh3201, while I wait for the kit, and it says, keep oil level up. Just trying to figure it out. Good video on the brushes, thanks
I have the same drill but my problem is that the hammer stoped working. I can still use the rotary thing but can't use the hammer. Any suggestions? Thanks.
Nice video. I have a Bosch 11202. It stopped working .I plugged the unit in, took off the 2 side covers for the brush assy. If I attache my meter probes with aligator clips and pull the trigger the drill humms like it wants to start, Do you have any ideas of what the problem can be? On the bottom of the drill it has a fan attached with a nut so I think it is different than the model in the video.Do you have any advice? Thanks Lowell
I have a Makita demolition hammer Its having a issue with hammering. the hammer turns on fine but when applied pressure it doesn't hammer properly, what you think could cause this?
Bill De La Vega Hey Bill, For conditions that are subject to vibration and heavy pullout load, use epoxy, Simpson set 22 is a good compound for retaining standard all thread, I know you are local to me, shoot me an e-mail if you need my epoxy gun for a few days.
Hey, Shadon. I got the same Drill and the chuck seems to have lost its ability to hold the bit,,,, I push it in and it feels connected but, it seems the drill is spinning but not the bit. Do you have any idea what happened? Eddie G
@@ShadonHKW Hey man, Ive got this tool just installed a service pack but i cant get the plastic on the front without locking the switch up, making it not able to switch. I Followed the diagrams, but no luck, I've attempted this like 20 times and had to take it back apart, Please help

Would it hurt anything to solder those connections besides making brush replacement harder?

BOSCH used to be the best...., now they SUCK!!!!!😐 Thanks alot China🤨🙄
Hi Stan! In my experience the vacuum connectors work much better.😂 Totally agree with your assessment.
Disculpen no ablo ni escribo español pero alguien podría decirme que tipo de carbones ocupa el tal

Nice work, our electrician said today that he had a Bosch hammer drill the local tech said was "unrepairable", will suggest he watch your vid.

Glad it helped, I can appreciate what these (new) drills cost.

Working live on a metal bench top?

Oh great video I have a hammer drill and it gets crazy hot after use any ideas thoughts answers would be great
Cooling fan blocked or broken, bad motor bearings, grease or oil level in the gear box.
I have the same drill but my problem is that the hammer stoped working. I can still use the rotary thing but can't use the hammer. Any suggestions? Thanks.
Awesome 👌 information... could just send you mine..I have two
My drill grabbing mechanisme is broken. Do you have any idea how to fix that too?
Cool I'm having problems with my bauer mag I'll see tommorow thanks for the valuable information
A voice as good as Mike Rowe on Dirty Jobs! Thanks for a great video
I need to know how to remove the chuck, this video did not help.
push down on chuck, 1/4 turn counterclockwise.
I have a Bosch I switched the carbon brushes turns on but throws a lot of smoke what could be the problem?
Nice simple repair on a great power tool!
Thanks for sharing!

Hi Stan
all the profesionals in europe are using Hilti for many reasons.
Good review, thanks for the post.
cheers
Mine just quit, for no apparent reason. I"m going to try this. Thanks for making this video!
Thanks for excellent Tip
Probably applies to other tools with similar brush holder/connections.
I am looking to purchase this part, does anyone know where to look for it?
I have the same tool with the same problem. Very expensive tool for 750 watt
I have a Bosch 11247 hammer only one of the speeds work, are there any videos on how to get the other speeds to work?
Hi Stan !
Nice fix - thx for sharing !
i ve done exactly like you done but it s now working
I have a Makita demolition hammer Its having a issue with hammering. the hammer turns on fine but when applied pressure it doesn't hammer properly, what you think could cause this?
+rocsvt1 Most rotary hammers have to warm up a little before they operate properly, the oil in the head is thick and needs to be warmed slightly.
rocsvt1 I also have same problem... Reason for that?? Any answer???
worn seals need's a service and new grease.
rocsvt1 junck bye millwalki and have no problems
I bet there's a bunch of those units left for dead when the fix is pretty easy.
Nice documentation of the repair Stan.
Colin ;-)
Thank You, nice presentation, fun to watch.
rh228vc bit will not come out?
Nice fix, thanks for sharing.
great video Thanks! i have the same drill that leaks oil at the bit; any suggestions on repair?
I have the same question
ok thanks ill check it out
You’re the man Stan!
Nice fix Stan. I saw the bottle brushes in your case that is a good idea. Any tips on installing anchors into the floor for equipment mounting?

@@miketartaglione5115 Not sure how to help you, I would have to at your bench with you, sorry man.
@@ShadonHKW gotcha, I actually just got it a few minutes ago!
i have a bosh 11241EVS it take a lilttle bit to slip into hammer .it will rotate but no Hammer or demo what could be the problem
Hi wilbur. I have the same bosh 11241 EVS AND I have the same problem as yours. Did you ever get it fixed?
No never got around to it
Great video
Nice repair Stan!
Good to know if/when my Bosch rotary hammer quits,
P,S, Thanks for the earlier tip on keeping some grease in case.
Hi mate.
Nice repair, however it should not be needed. Bosch, used to be a good brand, but now, like so many other brands from Germany they make a poor product, and are only trading on the good name they used to have.
