Repairing a Bosch GBH 5-40 DE Rotary hammer, FULL Service tool restoration.

[@stevewheeler3810]

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 !

[@rhalfik]

[@GreenJimll]

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.

[@jamesjenkins81]

He's like the Swedish Chef in the Muppet Show LOL. Great informative vids.

[@lewigas290]

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.

[@thibaultmerlin]

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!

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!

[@markopetrunic7598]

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.

[@blankblank-mx7dx]

Funny that you justify the cost of hand cleansers and the importance of caring for your hands and skin by saying “a few packs of cigarettes.” If you’re a smoker, I would suggest that rough hand skin is the least of your health problems.

[@Popeyes66]

I love the way you chuck things about Dean. Boy you are quick. You must have been whacking these tools about for years.

[@ilfordjedi]

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? 😊

[@T1nCh0]

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.

[@markopetrunic7598]

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.

[@BarniRepairs]

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

[@AlexKall]

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! 👍

[@Kresho85]

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.

[@TYMWLTL]

I've got the 11241EVS that won't hammer. It's got me stumped for now. Luckily I came across your video. I'm heading back down to tear into the tool holder hammer end to see if I can find something stuck. You are a master of these tools and inspire confidence in those of us trying to keep these good old tools running. It looks like your over in Europe by the sound of your accent and talk about euros for money ?

Hi Dean. Your repair videos are fantastic and greatly appreciated. I was wondering if you might be able to help me with a problem? I have a 20 year old Hyundai HD 5005 that is not hammering (the drill part works fine ). I took it apart and replaced the o-ring on what I believe is the striker (that gets pushed on a rod from a geared wheel) and I shook the other pusher out of the tube and changed that o-ring too. However I cannot for the life of me figure out how to get the SDS rod mechanism apart. Is there any way Zi can send you a picture of this for you to possibly explain how I take this apart? Are there two halves that unscrew? A circlip that I'm not seeing? Thanks. Jeff

[@YoramPomer]

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.

[@deandohertygreaser]

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.

[@YoramPomer]

@@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.

[@fireyourrocketts]

amazing, but how do I fix a woobling chuck? which part am I looking to replace?

[@michaelfairchild]

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.

[@barthanes1]

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.

[@deandohertygreaser]

thats an idea

[@markopetrunic7598]

@@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.

[@martinsamcreaone]

Nice ! , lot of work..

[@BarniRepairs]

Hello. What do you use to clean that grease off

[@Dustin_the_wind]

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.

[@harpintn]

I have used the Makita version of that machine. It will put a hurting on you as well if you don't pay attention.

[@Dustin_the_wind]

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.

[@patpending8134]

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.

How the hell does he remember where it all goes 🤯

[@markopetrunic7598]

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. ,

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!

[@markopetrunic7598]

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.

[@johncroasdale2748]

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".
