Which is the most reliable demolition hammer you can buy? Repairing the Bosch GSH11E soon tell you.

Iv said it once I'll say it again.
The Bosch GSH11E is one of the reliable and longest lasting demolition hammers you can buy.
25 years old amd still running strong. Like all tools, the old designs are always more reliable.
But unlike a lot of older tools, the Bosch GSH 11 E is still sold today and is one of Boschs best machines on the market.

My brother had one of these stored in the basement, which drowned during the Ahrtal flooding. It stayed under 3 ft of water until recovered. The pneumatic part is grease and therefore also water right. Electronics are also sealed. So I dismantled the motor, dried all parts cleaned rust stains, greased it and put it back together. Absolutely worth it.

Thanks so much!

Funny… As I’m glued to this screen watching you open the full service box I felt the presence of my better half looming over my shoulder then she asks “whatcha watchin?” Then before I could finish saying “Deans tearing down and servicing a well worked Bosch” she sees you crumple up and toss the breakdown schematic and says “pfffft, typical guy, he doesn’t need any instructions!” I just about spit out my coffee laughing. She’s right though, I think we ALL do that regardless of if we’re familiar with whatever it is or not! You’ve got quite the skill set brother, thanks for taking us along, I’ve learned so much watching you work your magic over the years! 👍🏼👍🏼 I’ve got two on the bench myself for today, a humming angle grinder and a dead 1/4” impact… Wish me luck!😉

[@peterparsons7141]

What I’m going to be doing is watch at auction and farm sales for these tools being disposed of. The big issue used to be finding schematics and access to parts. Because I don’t live in a city with good service centres we used to have to ship tools out, or pay “whatever” price someone would ask to take a stab at servicing. We used to be at the mercy of the local parts supply counter to locate parts, and it was hit and miss and expensive. WWW provides access to manufacturers sites, schematics , part #’s, and distributors and online ordering. Really good videos, well filmed and expert instructions. I think it’s fantastic , that it’s cost effective to revive tools. I really dislike using inferior, disposable things, simply Becuase they are inexpensive. I often end up buying better tools after having wasted time with the disposable stuff.

[@oliverdavidpatrick]

Bro it's crazy how you know these machines so well that you can just rip them apart and put them back together again like it's nothing

[@neilkidd240]

Buy quality and repair. There's also the eco argument. I'm an ex joiner with a number of old (20 yrs +) Bosch Blue tools. Sadly I don't have the knowledge to service / repair. ❤for your channel.

The collar with a spiral thread for shedding oil is called a labyrinth seal. They used to be very common and in machines 1960s and older they often are the only seal.

[@peterparsons7141]

Really good video. I wonder how many good machines you have saved from the scrap bin with this video. Over time this video is going to help hundreds maybe more. Professionals purchase good machines, and service them. As a DIYer I’ve always had to do simple repairs myself which can be difficult, but today’s world access to schematics and KZbin makes it much more feasible for many. I’ve always disliked purchasing new tools when the current tool was good. It makes me feel good when I can use (maybe abuse), a power tool for years and then clean it up, rejuvenate some parts, and off we go again. You do a good job detailing a complete rebuild, and all the steps involved. I have no doubt I would attempt this job, but would allow for significantly more time as it looks like you could do this with your eyes closed. I love watching someone who is really good at something.

[@edchristie4839]

In answer to your question, (as a diy enthusiast) if I ever had a tool fail it probably wouldn’t be worth repairing I only get the cheap stuff, Worx Ryobi and the like. What you do is an invaluable service to the trade, as the tools are their livelihood bringing in the bucks. I stumbled across some of your videos a few months ago and find myself totally absorbed in how you repair these machines. Keep up the good work sir.

[@Google_Is_Evil]

Pedantic: The part you refer to as "Field" is called the stator (from static) and the part that rotates is the rotor. Strictly speaking the alternating magnetic field is what makes the rotor rotate and can be generated by both the stator and the rotor, where one of them can have a static magnetic field but at least one of them has to alternate for the rotor to move.

[@UnderwaterSable]

Blooody love this channel although im never going to have to fix any power tools unless one of mine goes bad but i doubt as they do very little work and are kept in good condition i still love watching you take the tools apart and put back together as i alway loved taking stuff to bits myself. Keep the content coming. I would fixup the big expensive stuff but most proberbly throw out the stuff that would cost more to fix than replace.

[@ElMariachi1337]

Nice jobs again and gratz on the 100K! As for the 300 Euro repair I'd say in this case get a new one since these are still for sale and that one would get you another 20 years of happy hammering, bearing in mind that the electrical parts (speed controller/field/armature) also have made their significant hours of labour, so chances are one of those might break down in the (near) future.

[@philgallagher1]

Congratulations on the 100k, Dean!🎉🎊🎆👍 I know you work primarily on professional machines and you recommend Makita and Bosch. I'm not a pro, but am interested in DIY. What brands would you recommend for a DIYer on a budget? To answer your question though, if I was a pro and it was a fairly simple job I'd have a go myself after watching these videos. For anything more complex I would definitely get it looked at by someone like you before buying a new machine. Even paying the top quote of £300+ to get it back like new is better than paying more than double for a machine that probably isn't as well built as the "old" ones!😀

[@alouisschafer7212]

Would love to see a 1 to 1 comparison with a Hilti. In my experience (working at a large electrical general contractor) Hilti machines are equal to Bosch or Makita in terms of robustness, reliability and longevity. Now, Hilti may have longer lasting gearboxes, hammer mechanisms and probably higher grade battery packs but I dont think their machines are worth the premium. Personally I hate Hilti vacuum cleaners they are crap, too bulky too heavy and they break all the time just had to work with one that had a cable fault and broken latches that was fun... Also due to them not being round and having pretty large rollers the dust bucket is a absolute pig to empty out.

[@deandohertygreaser]

Hilti is not what they use to be. They are basicly a hire company now. Because of this they no longer need to make quality tools, as they keep fixing and replacing thier own tools. And they now fail a lot, never buy a hilti tool outright. They are a rip off. Plus hilti hammers have the red service light con job. They have a built in timer, when they run for so many 100 hours, the red light comes on and they stop working. The machine will not run again until it is sent to hilti to reset the light. They call it a service light, but once it comes on, you have to pay hilti to reset it regardless if the tool needs a service or not.

[@richardfife8192]

You dont have gloves? 😂 keep up mage work! Very relaxing intresting video!

[@rawcus918]

I could be wrong but I feel like using the brown grease on the needle bearings might not be a good idea. The eccentric gear crankshaft part was thin and so was the wrist pin. Going to be a lot of play.

[@fredholmes6284]

[@johnbullard5973]

I always think you can't go wrong with most of the bosch and makita demolition hammers. I've been seeing them on sites for the last 30 years. They are good value industrial machines when you take into account the decades of use you can get out of them and the availability / price of spares. I used to see a lot of Atlas Copco on sites, but not so much now. Do you get any of this brand in Ireland Dean ?

[@Bonswally]

I'm surprised to see a nylon piston and rod in such an expensive machine. There must be some advantage to it over steel. Weight or flexibility perhaps. Great video.

[@deandohertygreaser]

Its actually stronger. It has a higher tensile strength, but even better is it dose not fatigue as much. So a reinforced plastic piston and striker rarely fail

[@Bonswally]

How could that cork screw seal have come off? It is sitting on the shaft. Only way for it to fall off is when someone had the armature out. Then it is not the machine's fault but the repairman's.

Where do all the old grease, oil and nasty cleaning chemicals go? It will be a disaster if it goes into the drain to sea or land. Fixing one problem and creating another is not fixing anything. Instead of destroying it.

If you aint tossing parts around; I'm not watching your videos. ;-)

[@kknull15]

Why don't you use gloves when using parts washer? Kerosene is absorbed through skin and the effects of it on humans are largely unknown. It's proven however that animals absorb and metabolise it, and by analogy with other hydrocarbons, kerosene might as well be very dangerous. Also keep in mind, that all of the components of the grease you washed off parts, including metallic salts, are now floating in this washing solution...

[@deandohertygreaser]

True, it's not known if kerosene has any adverse effects. They are still on the fence on that one. But what it dose do is open the skin to allow other more dangerous chemicals and synthetic oils into the body. So yes, gloves are needed. I do wear glove for 95 percent of the work I do. I simply don't wear them when making a video like this. As they interfere when using the camera and cause the kerosene to get onto the camera and damage the controles
