Repairing a Bosch GBH 5-40 DE Rotary hammer, FULL Service tool restoration.
ฝัง
- เผยแพร่เมื่อ 30 พ.ย. 2023
- This is a Bosch GBH 5-40 DE Rotart hammer from 2008. Time and work have worn the seals and o rings inside, causing it to lose hammer action.
Looks like someone had already opened it and closed it up again incorrectly. As the change mechanism was not ingaged inside the tool. Meaning it was stuck in rotary mode.
Servicing any hammer is a stand repair after so much work. Every hammer will eventually need some sort of service to keep it hammering.
Bosch knows this and readily supplies a pre packed kit for the job.
Servicing a hammer can cost anywhere from 100 to 500 euro. Depending on the size and brand of the hammer.
But a good hammer can cost anywhere from 400 to 2000 euro.
So it will always be several times cheaper than buying a new machine.
The age and condition of the tool must be considered when deciding to service a machine or not.
When cleaning, check each part for signs of wear, especially critical expensive components like the armature, hammer pipe, tools holder crank, and torque limiter. Any excessive wear or damage on these parts can make the repair uneconomical.

I'm amazed by your knowledge of how to dismantle and repair every single tool, regardless of brand. And the way you just throw the dismantled parts around your bench without a care in the world, or worrying about which part of the tool they came from, is just outstanding! Kudos to you sir !
I think he repaired 21k tools by now. Imagine the experience.
This guy quite literally knows his job inside out. I wish I could find someone even close to this level over in Bolton UK to take my kit to. Great videos too 🤘😎🤘
Theres fuck all money in it,
And the biggest headack of a job,with 30+ things takin apart at the same time waiting on parts to come in
i'm a licesned powertool technitian and i love watching your videos. but for the love of god wear some gloves :D i used to work on tools just like you...and grease, cleaning solutions, oil and dirt damaged my skin, my nails... specially during winter.. when you constantly wash them with abrasive cleaners.. I thought I was unable to work in gloves...but eventually found a type that fits and protects...and still have a good feel in my fingers. not to mention....my wife is much happier. :D one pair costs arund 1,5 euros...and they last 2-3 days.. on a monthly basis...a few packs of cigarettes for clean and healthy hands. not to mention all the paperwork after the repair...my keyboard, papers...were all dirty and greasy.. now i just take the gloves on and off and continue with repairs.
15 year old machine and keeps on going, quality build. All needed was a full service and took 50 minutes by Dean.
Without editing or BS.
I love the way Dean casually chucks stuff across his workbench as he's dismantling tools. I try to keep dismantled bits in neat rows so I know what order things should go back in, but this man just knows his stuff so well he doesn't need to worry about that.
He's like the Swedish Chef in the Muppet Show LOL. Great informative vids.
Love how he chucked the bits on the bench could probably build it back together blindfolded 😂😂😂
I'm sure the majority of us will watch and appreciate any content you feel like providing. Top work Sir.
It's good to see old tools repaired, and the build quality in the original construction.
Dean, you are a master, if I undid stuff like you do I would never get it back together. Absolutely brilliant.
Your ability to dump everything apart and recollect it is impressive. My skills in mechanic stops at opening a pickle jar but your expert and straight forward motions are very educational. I've watch hours of your videos and I defeninitly feel like i've learn something. If i have a faulty tool i would try and see if i can diagnostic and fix one of the common issues. And i'll stick with Makita. Thank you!
140 and worth every penny.You really know your stuff.Well done sir
Where can I get touch with you I have power tools I need refurbished I live in kildare and I really like your TH-cam videos are you in the North or South
Like one hell of a 3 D Jig saw puzzle. The speed this thing gets put back together with shows a huge amount of muscle memory.
I think you’ve got the content spot on so I’m not sure specific tool reviews are needed. I tend to take notice of what you get in for repair and why you’re having to repair it. Case in point being the Mafell MT55 plunge saw. Nearly went for one but after hearing what you said about the switch fitted it put me off. In comparison you had nothing negative to say about the Festool TSC55 you rebuilt. This helped me choose. Having said that though I did enjoy the strip down of the Parkside and review of the intervals for that. Enjoy watching and learning all the while. Keep posting your efforts are appreciated by us all.
I do the same job as you. I see that this drill has been refurbished and runs very well. Your skills are very professional. The end result is amazing. Well done. Thanks a lot. ❤❤❤
Honest reviews on tools are always welcome, unfortunately many just shill a brand because of the benefits of doing so.
$pon$or$
I would be shilling any brand if they sended me free tools.
Great video Dean. I never even knew what a ferrule was until I stumbled across your channel. I use them all the time now with barely a penny in the swear box. Video wise I quite like the odd review though, as you say, only do them if you’re interested in the tool. Maybe a bloopers video once in a while? 😊
I would like to see reviews as in: THIS is the tool I recommend. There are hundreds of brands and it's good to get an advice from a professional tool guy who is repairing them and knows the ins and outs.
i can say right away - makita and bosch are great bang for buck on hammers and battery tools. but it's more about a whole tool platform...when you choose a brand...you should stick to it, cause od battery compatibility. for precision, durability and ergonomics... would say hilti and festool. but makita is my personal favorite... quite cheap and simple to repair and service, has a full range of battery tools.... has some great tools that are unchanged for decades....and available parts for 40 year old tools.
I love the way you chuck things about Dean.
Boy you are quick.
You must have been whacking these tools about for years.
Great the way you knock things apart. Putting them back together like it's nothing. 🇺🇸
I always find it amazing how he does it
Excellent video. Well done on breakdown and reassembly. Outstanding
Nice professional work; a pleasure to watch. Thanks.
If I was doing that job I'd be taking lots of photos as I dismantled each assembly, and lining up the parts in order of removal.
Needless to say, I wouldn't screw the parts diagram up and sling it!
Dean, excellent and informative video as usual. Thank you.
I want you to do what you want to do and do it with pleasure. Do not listen to the crowd. Doing what you enjoy long-term will bring you success on the channel. Based on the commments on milwaukee videos, i think thag would just bring additional stress to your busy life. Cheers from Romania
Love the way you just throw everything on the bench when stripping down.
WOW! The patience of Job!! So interesting. Thanks!
ove to here your top three tools in commercial and DIY categories.
Lovely job Dean
You work fast Sir! Thank you!
Excellent class! Thanks for the great information.
so impressed of everfy little component you know it! maybe this drill runm + 5-10 years more! glad yopu do this !
Great vids mate, learning soo much 👍
Would love to see some reviews and your point of view for different brands like
- build quality,
-durability/long life - for professional and home use and tools that have potential to be used in startup of small business,
- price/performance,
- what to stay away from.
Also levels of use for tool in different classes... for exp. there are a lot of Bosch drilling hammer tools for construction. It would be great to have an idea where is the border where you don't overbuy for your need. For one big project like punting up a house you need something dependable for a short period but not the most expensive hammer.
Maybe reviews Of Parkside from Lidl and Ferrex from Aldis/Hofer. They sell a lot of machines. Are they all garbage or is something good to own from there?
In a recent video you commented that Milwaukee tools are not so good, DIY tool with hefty price. I have been quite surprised, a lot of businesses use them including at my workplace and I have been considering buying my next tool from them. Bullet dogged.
Thankyou for sharing your knowledge.
very nice job like the explanation at the end of this one especially
Very util Video, Complet repair of Hammer Bosch
Great video bonny lad.
I find your videos informative and soothing. You know your tools, amazing. 73's Andy M6APJ.
Full credit to dean for fixing these tools but look how complicated the design and engineering that’s gone into the product impressive
So interesting to watch obviously you know these machines backwards forwards and inside out.
Looking at the list of videos I viewed: I mostly prefer watching a single tool getting repaired. Or a single type of tool (like several rotary hammers).
I serviced and repaired one of these yesterday
Do you ever get any table saws in for repair or recip saws?
Nice one Deano. You should make another channel with all the videos just without all the swearing edited out 😂
Love the content mate, fascinating stuff
Love the job you do to these tools. Thanks for your instruction and the time you give!
I love watching u as nuch as i love watching the famous GLASGOW RANGERS..SUPERB
Thank you Sir
Random guy owning this machine:
- Maybe I can watch this video and do the service myself.
After watching this video:
- Nah......!!!
Dean, could you do a movie about your cleaning machine? How is it build, what fluids do you use with it? Some kind of walkaround, please.
AMAZING!
I wouldn't mind reviews, I would appreciate them hearing what's mechanically good, if the machine is well built etc based on your was experience of fixing power tools. Knowing the repairability of the power tools. That would be invaluble information to me, when considering buying a tool! 👍
Also, awesome repair as usual, amazed at how you can remember where every little part and screw goes! Way better if we can repair tools than just buy new ones if it's financially worth it, saves money and resources! Great video! 👍
Brilliant how he screwed up the diagram & threw it no need for that he really know his stuff
Simply INCREDIBLE skills.
Love how he just lobs it all with absolute confidence, that's a man who KNOWS his trade.
How do we contact you?????????
70k ! when 100k i will celebrate 🤩
🤞
I know how you feel about TTI products, but a AEG AFNDA180 would be entertaining because of it's uniqueness.
you got this!!!
How the hell does he remember where it all goes 🤯
after hundreds of machines it's simple as breathing. i repair mostly makita tools, and i can replace an armature and full service kit on a hammer under half an hour. cleaning parts takes most of the time....putting apart and assembly is quick and easy...you just need 3-4 years of experience. it's even easyer if you specialize just one tool brand. for example...where i live is mostly bosch and makita... and once in a while i get metabo...dewalt or milwaukee.. basically they operate on a same principle...but have some diferences on how they are put together...or tools needed fot the repair. this is a great channel, work seems very complicated for a average Joe.... but for us technitions...it's a walk in the park. plus..if you have something complicated...all brands have excellent aftersales and tech support, with diagrams, part numbers and even assembly numbers for putting parts back together. but i can't remember when i last used that.
,
amazing, but how do I fix a woobling chuck? which part am I looking to replace?
Hi, thanks for vid! Is it just a little grease going into the head or is oil being poured?
Maybe you need a large ultrasonic cleaner for the thinner. It seems like it wouldn't expose you to so much if it wasn't splashing around. And less work too.
thats an idea
@@deandohertygreaser ultrasonic cleaners are good just for carburetors. the amount od grease and dirt in powertools is to much for a ultrasonic cleaner. nothing beats a brush and a good cleaning solution. plus a big air compressor just for dust.
That was like a soldier striping his rifle down
Dean., when you rebuild and put it back together with new brushes and you plug it in and get a red light, how do you reset it??
When on spare parts it actually states "Made in Germany". Thats why I love buying Wiha, Wera and Knipex. Most of their tools are still made in Germany, Czech Republic or sometimes Poland.
6:25 gave an ulcer. How does this genius keep track of these parts???
Hi Dean, I wonder why you use grease instad of following the Bosch instruction and jsut dip the stuff in OIL ?? No worries that the Greas you use wil have impact on the life of the later added oil ?? What Greas do you recomment ? that would be a very useful hint ... Your Explanation Video is outstanding Very Nice done !!!
Pretty sure as long as you stick to lithium (White grease) it will be fine
Do you ever do snap on stuf
I wonder what is the oil grade that you put in the gear case?
You are amazing, I think you can do this with your eyes closed.
Does kerosene leave a residue mate and is it fast drying also what electrical cleaner do you use thanks pal
We in the UK called it paraffin when a was a lad...bum..bum..bum..bum... Esso blue, showing me age now like..😂
There's plenty of review videos on TH-cam. Your content is great as is, but your thoughts on tools the average Joe uses would be interesting.
This is a very impressive work. I would need to take a picture of everything that I take apart , so that I can put it back together :-)
I saw that you are using several type of grease. Could you explain the logic behind the different types?
Thanks for the sharing.
There is no real logic behind it. One grease will do fine. I simply like to use the heavy bosch grease when building the machine. The finish by filling with the correct grease.
The heavy grease will help male a better seal and protect the greases on startup bit it will quickly mix together after a few seconds running. So it make no odds it really just makes less mess for me when rebuilding.
@@deandohertygreaser Thanks for your answer. The original grease from Bosch is so expensive, so that using a single variation instead of 3, will also save me money.
Hello. What do you use to clean that grease off
Thanks for sharing and showing me how it works, Dean.
I've ran this machine enough to know to watch my skinny legs when drilling down through rock filled concrete, or elbows when drilling at shoulder height through 12" foundation; it'll kick your butt if you let it.
Quality drill, I will attest. Does this same design model get larger? It's nagging me that it does; the one I frequently used had that design, just seems a bit smaller.
It ran big, and long bits, got heavy sooner than later, and I broke a 140 dollar 1 ⅜ bit on stone if that is relevant information.
I have used the Makita version of that machine. It will put a hurting on you as well if you don't pay attention.
Yeah. It got me a few times.
I really think I was running the next size up version of the model, took a bind up to my knee drilling a afterthought hole for a condensate drain in a fireplace foundation vault, being the most memorable.
I wish we could see you unplug the machines before you touch the internal electrics! as we dont see it I always think "has he unplugged it!!"
Hi Dean
Great channel!
I have a GSH 5 demolition hammer. Great machine. Is there any way to convert it to a rotary hammer? Internals look similar to the one you are servicing in this video. If I ask here in Cape Town I get a blank state....with a firm NO!
GSH and GBH hammers use the same armature, but that's where most similaritys end. different tool holder, no selector rings, no selector, no gears, no clutch. GSH are much simpler than GBH, thus lighter and better for just one operation - as a demolition hammer. there is no way you can add a drill function on a hammer. next time just buy a tool with both functions. that hammer has it's use - for plumbers and electritians and instaling piping and cables.
Marko
Thanks for reply. Yes, 2 days after buying chipper in 2018 I realised that I should have bought the GBH. I have not had much need to drill 40mm holes until recently. So off to the hire shop I go. Thanks. John
Grande dimostrazione splendida una domanda main italiano non è possibile grazie.
Do u work on Hilti
You recommend Bosch and Makita hammer drills, due to quality and ease of repair. Any thoughts on Hilti and Metabo? Overkilled prices?
Metabo is a lower price option but don't last as long. Would never recommend a hilti hammer these days. Over priced and no longer last.
@@deandohertygreaser Thx for valuable info Dean. I know this is asking for something aside your repair/service videos, but do you foresee any possibility for making a comparative video where you discuss the pros and cons of the different brands for each category (drills, grinders, saws, etc ) and which brand you'd pick as a platform for both a DIYer and a pro (price vs durability/serviceability) - like you did in the video "Impact wrench, pro's and con's of the top 4". There are lots of channels comparing brands and models, but absolutely none have the expertise or excellent way of conveying it as yours.
Bonjour beau travail j'ai changé les joints mais il ne frappe toujours pas avez vous une solution merci
Na Dean we want the strips and the bits, forget about scripts and scriptures leave that to the movie people. You have enough vids out there for people to make up their own minds on what they want and need and you have said eough to help them along.
I used to pick millwakee tolls till i watched dean..
It looks like a well made and robust tool. Something we'll worth servicing instead of replacing it.
Are Bosch fairly good in terms of getting parts and service kits for them?
bosch is one of the best
@@deandohertygreaser makita is even better, has available parts for tools that are older than me (40+ yrs) just finished repair on a 1805 planer....all parts are still available, wich is amazing.
@@deandohertygreaser I bought a TrackSaw system from them as well as some of the 12v tools. I do like them.
yeah go ahead a do reviews also, I don see any reason why not, you can always add another perspective

Who is your flannel shirt provider?
👍👍
A photographic helps easy to take apart if yo know where to start but why do I have things left over? 😂
Dean, Thanks for another excellent video. I would NOT like to see you working on cheap brands etc. There is enough cheap rubbish in this world and it is entirely that you taking some of it apart would simply confirm the obvious, e.g. cogs made of plastic, no replacement parts available, uneconomic to repair and the tools being throw-away and only fit for DIYers. Your videos provide a glimpse into the world of professional tools and that is why they are interesting. Your views on Milwaukee tools were revealing, including the 5-year warranty people in the USA get. I'd be interested if you ever do a video of Hilti tools, as I understand they are very high-end. You could maybe do a video of your Top 10/ Top 5 brands, as we'd be hearing that from you as a real expert whose opinion carries weight.Thanks again fro the time and trouble you go to to make these videos for us.
Tool snobbery...
BS doesnt matter the brand, at the end of the day almost all of them are disposable, specially nowadays
Personally, I'm not interested in review videos unless the product is groundbreaking in some way. I just like seeing old stuff work again.
Hi Dean
Have u tried petrol for cleaning
Yes I have. But it is simply to dangerous for a workshop
A parts washer filled with petrol? Extremely dangerous a major fire hazard.
@@alouisschafer7212A parts washer?
Watched quite a few now. Not seen any Hilti repairs. Any reason why?
i stopped taking them in. hilti quality has dropped dramaticly. There will soon be in influx of them so im getting away from them now. plus they charge 30 euro p&p for even a single o ring. and a lot of the tools have a built in serivce timer. once the time is up. they shut down and will not run again until you ship it of to hilti. (basicly its a con)
@@deandohertygreaser thanks for letting me know.
Out here in Asia we buy a lot of hilti equipment. They market themselves a lot, but I think I will start looking around at other brands as they are not cheap and do charge a lot for repair, so there is a tendency to use until broken then throw away and buy new (very wasteful).
Love the channel. 👍
Have you worked in any air tools (CP9 or an FL22, old school hand mining machines). Would love to see one of them stripped down and rebuilt.
do you repair toyotas
😊😊😊😊😊
Tool doctor
I have the problems
Bosch or Makita hammers?
Yes.
I bet Dean would say Bosch. Easy to repair reasonable parts cost and he is a service agent at the shop that he works at
NO TOOL REVIEWS!
Why are you throwing parts all over?
72 euro on parts
A days labour
And the hole repairs cost 140e
Far to say how do u make a living?
