Repairing a Bosch GBH 5-40 DCE Hammer that has started eating itself. 

Dean is a man who has perfected his craft. He makes it look easy because he's been doing it a long time. That comes with repetition. People say I make my craft look easy, but I've been doing it over 20 years. People can do it if they're willing to put in the time. I'm actually looking for old broken tools, just so I can try this while process. His videos are very well done and informative. Thanks Dean, you're the best

Highly unlikely, but hopefully Bosch watches this and takes care of your customer. You are Bosch's best salesman. You shoot us straight, while you're tearing their stuff apart, and praise them normally.

Bosch should honour this mans warranty, tool failed through metal fatigue, evidence is here courtesy of Dean,s superb,workmanship and diagnosis, do the right thing Bosch!

And that's her! the bob ross of tool repair

"It's just self-assembly." Well, for Dean maybe. Not us mortals.

Definitely saved the owner a few euros by not having to buy the whole repair kit. Lucky you have such a great range of stock. Another satisfied customer.

I think Bosch could be persuaded that this type of fracture on a striker bolt was a manufacturing defect and not as a result of normal wear.

Your customer could send that faulty part to Bosch Uk. They may refund the cost of repair due to the strange failure mode.

Dean. I work in the electronics industry here in ireland. Not commented before. Love the way you broke down the component parts of this hammer drill. Made it so simple. Based on your videos I’ve taken the same methodical approach in my own industry and encountered an issue with a touch panel from a well known controls system brand. Needless to say, I took it apart and recorded a video of what I was doing. I found the flaw and am surprised to say was able to fix it with a bit of solder and a cable tie. Happy customer. Never would have even attempted it had I not been so lucky as to come across your RU-vid channel. Keep it up. You are a master at your craft. Very few folk left like you these days. Trust me, I’m of the generation that sits between what is now and what is yours. Would love to come and work with you in the shop some day. That would be an experience.

A nice video.I think bosch should own the defective quality and send the replenishing spares used

Good evening great video thanks again for your video 📹 👍 😀 all the ways from the Philippines 🇵🇭 one of the best 👌 👍 😍 🥰

Surely there must have been a wierd defect in that part for it to split right across like that. If other people see that failure on a young tool again - Bosch needs to find out why. As ever Dean your videos are very well narrated. I learn more from you every time. Especially diagnostics.

Great one, Dean Keep em coming!!!!!!!!!

As i dismantle something i try to set everything in order for rebuilding its amazing how you just scatter bits here and there and get her back to gether again

It won't hammer......its not unusual it happens all the time.....there's a song in there deano....lol 👍🏴󠁧󠁢󠁷󠁬󠁳󠁿

Another great video. Thanks.

"Unusual" I dont think it can top up the "Do It Yourself" sander in a shoebox from year 2000 from previous video.

Top job as always pal

Thanks again for a great video.

Your videos are awesome, you inspire me to ttry and fix my fathers Bosch GGS 18 V-LI that he was gonna throw out the motor was loose and had spun around and cut the cables, fixed it as best as i could and the maching went smother than ever keep doing what you do!

I love your videos. You are the Louis Rossman of tool repair

Quality. Thank you.

Thank you Sir

Cool! Fantastic man

Best one lately!!!😮

Dean is on the job

Experience counts, good job mate 👍

I really love watching these but damn you need to get yourself 20 different gloves and try them on until you find the one you like haha

Great work, as per the norm. Nailed it right off the bat with a twist. Hopefully customer did so the online rego.

Dynamic Dynamo Dean !!!!!!!!

First, congratulations for the excellent didactics with which you explain. And secondly, ask you about the two fats you use. From already thank you very much

We had the strike lock up on a brand new hammer a year ago or so, it was never even used. I think i now know what happened, probably stored the case on its side in the van. it's a nice hammer but i really hate the trigger design, everyone always accidentally turns off the hammer while handling it.

It's a good thing you showing the downturn of Bosch quality. We builders are watching! Thanks, Dean!

The parts that had failed. Will you send them back to bosch for them to have a look at.. or will they go straight for recycling? If it did ho back to bosch it would be nice to hear an update from them after they tested it.

Hello I have the same model and I have two question it seem that I can't control the chipping hammering very hard to aim it in one direction the other question the top we're the grease and piston is located get very hot these are my question thank you

800 Euro 😱😱

👍👍

we have a 11241EVS, dad bought it more than 20 years ago. We rarely use it, maybe 0-3 times a year. Recently it didnt want to hammer, have to pull on the tool holder sleeve to loose the chisel and somehow the hammer would then work. once it warmed up it stayed hammering until the job is done. But I was curious and opened the cover to check it, all the grease is black. And damn, I didnt know you have to put back the screws like that, i just straight up screwed it back in. Did I screw my hammer?

I wonder what caused this mode of failure? A defect in the metal of the striker pin, perhaps?

Just a matter of interest..did you show the customer the damaged part Dean

Could the pin have had a flaw in the crystalline structure of the metal ?

What's the part number for the light grease put the gear casing? I serviced one of these but went with the mineral oil, should I replace it with the light grease?

Bosch quality these days

👍👍👍👍👍👍👌

What kind of assembly grease do you use?

Ill stick with my Milwaukee unlike you had bugger all problems with any of my tools n love my 5yr warranty, electric problems on couple Milwaukee fixed within week no questions asked.

Must be a manufacturing issue.. A striker pin must be made from some of the hardest most ductile steel you can get for it to last at all. So this pin must have just been forged incorrectly or the root cause was impurity in the steel who knows. Bosch should be notified about this failure.

And I see you used a single shim. When I disassembled my tool, it had two shims. Which is correct?

whats that little keyring torch youre using Dean? good bit of kit

Hi Dean, we're you an employee who of ToolsStream?

To you all those parts look simple when divided in the desperate parts, but to the rest of us that probably haven't seen those parts before, it looks like having to do brain surgery 😂

This was clearly a case of a manufacturers fault and regardless of Bosch warranty policy they should handle this one under warrenty even after 2 years of manufacturing date in my opinion. Unfortunately Bosch is not the easiest when it comes to warranty cases ...

Interesting fault. Does Bosch collect reports of such incidents ?

No matter how long the warranty is this is a Factory fault and should be replaced without raising an eyebrow. Does Bosch produce their tools now in China? I hope not! Thanks for sharing from Mexico

Bosch quality has gone down the drain. Everyone should avoid them.

Ah, good. Chinese metallurgy - emphasis on the lurgy - spreading to the workhorse brands.

2:52 Are you sure it couldn't possibly be a bad 'turbo', being it's a *"Turbo Power"* version?😂😂🤔🤦🏻‍♂️ 🛠️🔧🔩⛓️👌🏻👍🏻🚜🏗️😂

I hope Bosch is watching, this has to be manufacturing fault as this machine has not seen much work at all. Lets just hope it's not the beginning of the end of Bosch quality.

What torch is that on your key ring?
