That rebuild was amazing Dean. You are a truly gifted technician.
I have watched plenty of your fixes and service uploads, Today I pulled apart a (PRO tm 18v) rip saw I was given a few years ago it's a cheap thing and would not run even after I charged both batteries.
After a clean and a little tab bending the thing is back to work, thanks to the confidence I gained watching you. Many thanks.
Always makes me smile when you have your hands deep in dirty thick contaminated grease, yet the the clean grease gets spread with a paint brush. Great vid again as always.
Well if I used my hands with the clean grease I would also be getting the newly cleaned machine clattered in grease also.
@@deandohertygreaser You should really consider using some kind of precision gloves, grease is not good for your hands especially if you do this multiple times a day. Take care 😊
An important part was installed upside down, compare 18:32 with 41:32. The round part with the two 180 degree offset lugs that struck through into the rounded grooves in the tube, that part is upside down.
Otherwise an excellent job as always!
I wonder if he saw it on the video editing and corrected it
Hello dean uncle I am from India. My father also does the same work. Your videos r full of knowledge.
How on earth do you deduce he's your uncle??? No, seriously?
@@kevinchamberlain7928 Sir, Your comment just makes me sad. The fact that he calls him uncle, is just a sign of respect. Many cultures does This in one shape or form. Please read a book. No, seriously do.
@@tho4747 Which book would you recommend?
@@tho4747I’m pretty sure he’s making a joke.

112k in subscribers well done Dean. That demo hammer is really built to last. Probably it's first service and she lasted 12 years which is testament to the Bosch hammer's build quality.
I watched the whole vudeo without batting an eyelid nit to miss the placement of any part.Great job Dean.You know why a part is made and that majes your skill show up everytime.
Well thought out and executed Dean, always nice to see you work on a machine you haven't worked on before. I knew with your expert eye and knowledge that you would have this (upside down) beast up and hammering again no problem. Keep em' coming Dean, great work.
Quality work. A definite A. As my old instructor used to say A is what you get when everything goes together and works as required. A+ is when the unit gets disassembled by an engineer to validate all the work. In other words, strive for the A+ knowing that the perfect repair does not exist. Everything that I have ever fixed always had a time, money, material and is it worth all the above to do. 😊
I kinda like the design with the motor part on one side and the mechanic part on the other, being able to work on whatever side you need to be for a fault.
Thanks for the full stripdown, even though I haven't seen this one comming in for repair either.
Damm, new video dropped and i have to go out after only watching the first ten minutes. It will be a midnight treat for me later tonight. Bosch and Makita seem to have market sown up for these type of hammers over the last 40 years i've been working .
Thanks Dean,I’m usually out for a pint a bit earlier on a Friday, but I was 1:07:30 minutes late tonight, great video
You'll have so catching up to do then. 🍺
Funny, I’m watching this with a friend so when reassembly starts he says “how the heck can he remember where everything goes?!” “ Didn’t he say he never saw one of those before?!” “On a good day I’m lucky if I can put a few smokes back into the pack if I drop my cigarettes and some fall out!” I’m dying over here lmbo! Nice work as usual, thanks for taking us along…✌🏼
What a wonderfully complex whacker!
this is what years of experience looks like.....
That big washer with the half circle lugs on that the bump sits against you have installed it in the wrong direction the half circles face the longer part of the pistons cylinder, I watched it back before it was disassembled.
noticed this too, hopefully not a big problem, looks like it might interfere with the plastic part.
Hi Dean. A trick for fitting lip seals. Use an old fairly long o'ring put it thru the inside of the lip seal and you can roll it round pulling down past the upper seal grooves down to the bottom groove. This also protects the new seal from damage which a screw driver can do. Hope you understand what I mean.
Dean
Terrific video. Everything about this hammer makes it look like it's been on steroids. The key distinguishing feature for me is the size of those retaining pins in the hammer tube - normally about 6mm dia in other Bosch rotary hammers - these ones about 12mm ! It was clearly designed and built to do a lot of work and to last. Great job.
Best regards
The beauty of a Boschhammer.
Very durable and well designed machines that are rebuildable.
It must be some machine, if that's the first 1 you've serviced, and it's a 2012 model.. That says a lot..
They're not popular, at least in europe if youre needing that kinda of power you're using either expensive hilti or "cheap" no brand names.
If dean has never worked on a tool , once he gets into it, it all comes back to memory
You should do some 'That's her' merch.
stupendo lavoro il migliore visto del genere complimenti nel tuo lavoro sei un artista grazie mille per condividere con noi quello che fai ,ancora un grazie e ciao
Good work, Dean. That's one helluva tool!
Fantastic.
Bravo what a job
Fine machines these Boschhammers.
Hi, your videos are better than Netflix, but in this one, you made a mistake with the placing of the washer with ears at 18:15 vs 45:01.
Noticed this as well and was looking if anyone else has noticed it. Of course someone has!
Goodness that looked a tricky job Dean. I've just serviced a Hilti TE 52 and that was a breeze compared to that.
Love the speed cleaning
You did very well, well done
What a machine. Wow..
You were great as always
I was waiting for the rabbit to come out of that hammer casing 😂😂
New circlip pliers
Great job young Dean! Good watch as usual, has any tool stumped you?
Not yet!
I don't know about you Dean, but your channel is ripe for a hand cream sponsor like Okeefes working hands - You're hands must get absolutely battered despite you sometimes having gloves on.
Thats a monster of a machine - 23J of impact for about £900 in the UK.
40v XGT content come on the lads in Donegal demand some 40v kit in the shop.
Thumbs up
Must actually buy a few to teardown and test out
@@deandohertygreaser have you had any in for repair yet?
Hey Dean, Pos. 54 Control Disc was assembled the wrong way round, this may cause the perforated ring (Pos. 36) to fail, doubt it’ll cause damage to the hammer as its plastic but its just an observation for the next one. Ps. keep up the amazing vids, love watching you and learning at the same time :)
Why the brushes looks okay when then machine has clearly done a lot of work? Have they been replaced before?
More than likely, it is over 10 years old
Nice job well done
Great video Dean
Have you got a long for your reversible assembly driver bits please?
Well done for the first time. Service the next one will be faster.

Perhaps this tool was being used horizontally in a wet trench. So it's clogged with all the grit & grime it was working in.
It's a heavy hammer, without being far to heavy to work horizontally
"Never worked on one of these machines before" immediately starts throwing screws😂
Those metal fins on the aluminum body are interesting. I don't think they're for heat exchange, looks as though they are to transfer impact energy away from the bearings. And possibly the handle? Pretty cool. I like that the power cord goes forward too, so you're not always kicking it around.
saw the same
Hi Dean i am not sure you put the seals on the striker correctly. As one of the lip seals will keep the grease in, the other outer one would be put on backwards to keep water and debris out, not saying i’m correct but i have seen hydraulic pistons do this
No that is the correct way. I thought the same myself or was going to fit the oring to the bottom. But bosch them for sale fully assembled amd that is how they fit them.
Makes sense as they do a dirty job as you can see for the ones removed. But the hammer normaly faces down so grease is more likely to leak out than dirt to leak up.
@@deandohertygreaser ahhh, fair enough! I thought if dirt gets in the chuck it would pull it up and past the seals
Hi Dean, greetings form Czech Republic 🇨🇿 love the video as always 😊. I'm a mechanical engineer, so it's interesting for me to see how these things are constructed and how they are then repaired.
Just one question, i was just wondering if the two lip seals on the striker should be facing the opposite way to each other. So that the first one is facing out of the hammer and keeps the grit out, and the top one facing in and keeps the grease in 🤔 ?
No they both face the same way, the original model actually used all o rings and most hammers use orings. Only ever seen the lit seals on older hammers.
How do you remember where all the part's go Dean
Bigger brain cells 😂 and a lot of teardown 😅
Hi Dean,
What grease do you use for the sds is it ngli 2 or 1
Hey Dean, I found those seals will work again if you leave them for a day or two to 'dry out' or if you put them in the freezer.
What is your opinion on the Bosch RH540M hammer?
Good video and on first one every one makes a mistakes, sorry I don’t want to be a smart guy but easier way is to put steel washer and the spring in the housing first after that hammer pipe , for the hammer and pistons you can put it if you like at the very end, and maybe u done it right after video but in video you had placed that control disk in opposite direction
Yea, it was grate fun the next day after editing the video, taking it all apart again to turn it around
I crack myself up every time you throw the parts on one pile and I wonder how the heck you get that pile back together. ha ha I remember when I was a kid I had always leftover screws
salve nella vasca di lavaggio che liquido sgrassante usa?cosi so dove comprarlo grazie
I somehow don't think I'd ever attempt to fix something that complicated. I think changing brushes or a plug fuse is my limit.
Thats a big boy
Thats what she never says to me 😂
@@deandohertygreaser😂😂😂
@@deandohertygreaser😂😂😂😂😂
sum amount of cleaning there dean 😂
Tell me about it
Hmmm wonder would kero work in an old dishwasher without an explosion
Put the O rings and the seals on the striker in reverse
Dear Lord!!!
Look at the size of that crank gear!!!!
Mighf as well be the flywheel on my pickup truck
You'd be a long time wearing them gears out
@@deandohertygreaser indeed!!! A long time!
It has to be a cut gear.
No way they cast that crank gear from powdered metal
Far too important
"look at the size of that, thats huge" thats what Dean said
Literally said that as soon as Dean said it, "That's what she said" 😅
Every thing is heavy duty metal. And then a plastic piston? ??? Is it because that only component thats moving and they want to reduce the mass?
The plastic piston and conrods are actually more durable than alu ones. Plus alu and pa6gf30 have roughly the same tensile strength anyway. So a nylon one is the better choice. Plus they also have other advantages main 2 being. They are cheaper to produce keeping costs down and if they fail. They cause less damage to other components inside.
Yes they are lighter and work just as well if not better.
Aluminium conrods seem to snap in half more often destroying the gearbox.
The piston only compresses air anyways.
Hi Dean, amazing video as always. I would be the last person to comment on the Master's work but, seeing you struggle with that c clip, could you not compress the rubber bung with two vice grips, one each side to make removal easier ?.... just a thought 🤔
Yes, that would be a out easier. Only 1 problem, I don't have 2 sets of vice grips.
Hi Dean you did a review video on nut drivers a while ago, any chance you can do the same for cordless grinders 🙏🙏🙏
I'd like to see that 4 1/2 & 5" heavy and light duty - you can get 700 watt and 1400 watt variants from the big 3.
@@shifty277 Good call 4 1/2 and 5 inch 👍
Thanks men for video ❤
Chock full of Winnit Paste!!!
Are you sure it should not be 3 o-rings on the striker? According to the parts diagram it should be 3x 1 617 000 756 o-rings 🤔🤔
Probably been upgraded. The old old ones where the same, 1 oring and 2 seals.
They also came in the service kit for this hammer
@@deandohertygreaser Okay.. Might be.
@@deandohertygreaser Also noticed that part 54 (1 610 190 069) is the other way around at assembly, compared to disassembly. At disassembly the flat part was against the washer, and at assembly the round side was against the washer. Don't know if it matters.
At 46:17 you can see that the rounded part doesn't match up with part 36 (1 610 190 066) that goes outside the tube.
Dean … what you like at jigsaws ? 😊
The gsh 11 vc is a masterpiece that the Chinese still cannot photocopy, it is purely German, the Chinese models are useless and its manufacturing quality is very low, like the iconic gsh 11E that is currently manufactured in China, being a copy of the other low quality brands The only one that looks like the gsh 11vc is the parkside pah1700 model but it is still Chinese and that model cannot be fixed, it cannot be repaired. Everything that comes from China is not useful in large works where the machine and even more effective percussion must be required. Many models offer 50 or 70 Joules and can't even match the punch of the German gsh 5 CE even with its 8.3 Joules it is still a better option than most photocopied Chinese toys.
