- Don't get to many of these GSH 27 Hammers in for repair.
Amazing hammers they are, brilliant build quality. A nothing but steel and persicion.
Unlike a modern hammer with o rings for compression, this old beast uses persicion parts that seal themselves with only grease.
That is what the problem is here. The grease has dried up amd no longer sealing the hammer inside the piston.
wash out the old grease and install some fresh grease, and she's up amd hammering again.

Tight initially, then starts sliding. Quote of the year.
LOL
Sometimes I spend my Thursday night watching an Irish guy rebuild power tools on CZcams and I’m okay with that
Respect to the blokes who are lugging one of those around all Day!!
Beast of a machine. Given the age and lack of grease elsewhere, was sort of surprised the o-rings on the bolt were good. Very nice job!
I love that cronstruction yellow colour of the breaker. Takes me back to my childhood looking for Hymacs and JCBs.
Thanks for another educational and fun video.
Now I want to buy one, just to make that Manly cup...cheers Dean! 🤔
im a 20yo apprentice plumber and we have one of these exact jackhammers im pretty sure its older than i am and damn is it reliable ive used it to bust out 1000s of lbs of concrete and it never fails to do its job effectively.
That's the first time I've seen a Bosch with Stanley yellow.
You always explain everything so well! Thank you!
Dean is the Conor McGregor of repairs ❤
Nah mcgregors a scumbag
Love the comment about the “manliest cup ever” 😂
That gives me an idea for a future video Dean - how about showing us some of your repurposing projects - made out of spare parts - do you have any to share with us?
Keep up the great videos 👍
When stuff was built with durability & repair in mind.
The changes that has been made to this model, compared to the old USH 27 and the new GSH 27VC when talking service etc. is minimal. Oh… and if you want to talk about how things were in them good ol’ days, then the reference would be the USH 27 which look identical to the GSH 27 and for except a few parts, is identical. This Yellow GSH model, was in production all the way up to the late 2000’s But, again, the yellow GSH27 and the blue GSH 27VC is all as strong as ever. Doing maintenance and service is same same. If anything, the blu VC is run better during use.
To be fair, the GSH 27VC is a better hammer than the old USH27 and the GSH 27 in all fronts, I can promise you.
Does this goes for all power tools, absolutely not. But the 27 is still going strong.
More knowledge & great content as always looking forward to the next video to drop.
Got a bit of a workout with that one Dean
Very nice job Dean. Pretty sweet!!
8:11 "Manliest cup ever!" Nice one Dean! 😄👍🏻👌🏻🛠️🔧🔩
Holly...that's a big boy!
Awesome 😎
12:29 That's what she said.
Ok, that piston is mental
Well done, nice video.👍👍👍👍👍👍
Ha! The manliest cup ever. You don't even have to cut it down, that little hole in the side just adds to the challenge of drinking.
The manliest cup ever had me cackling 😂
They were a great tool kango used to make a 2500 and a 1800 aswell
Those hammers need to be stored upright, if you lye them down with the chisel slightly higher than the body the hammer piston can slowly slide up into the bore and get stuck in by vacume & can be very difficult to get out, bosch sell an overhaul kit with tacky grease & o rings etc, decent hammer.
Didn’t even realize they did hammers here. I remember they had a whole ass factory just for drills, went through that phase with Skilsaw and had one or more factories from an acquisition (was it a Stanley power tools operation?). But presumptions were always Switzerland for Jigsaws (now Hungary) and Germany for hammers.
Back in the 80s I used a jackhammer like that but maybe not that brand but I was also the guy that would use the 8 lb Sledgehammer to bust a concrete Etc
The lightest use to be. A machine mate.
Just sold one of these £350 👍🏻
Great video!
Maybe you can recommend best garden tiller brand?
Last thing I saw "Made in USA" by Bosch is the selfcentering bits which Ive bought, since you cant get them normally in Europe in metric.
What brand/type of grease are you using?
Crikey. Ten minutes hanging on to that thing and say goodbye to your fillings,..😮
Omg hope there is no one downstairs 😮
Isn‘t the chisel locking lever mounted different facing up when locked?
Seen smaller hammers on mini diggers.
Dean, what grease are you using in it?
Bosch hammer grease
@@deandohertygreaserdoes it have a “generic” equivalent? - the greases sold under the tool brands are a tad expensive. Just paid 20 quid for a pint of Makita grease.
Did you need to use any replacement parts? O-rings, etc.
HIT THE LIKE BUTTON!!!
What is in this yellow bucket? Just concrete?
@@kevindavis7868 It’s an old transformer Dean uses it to test the hammer on a tool Better than knocking lumps out of the floor
Was wondering why not use the air compressor to get the hammer out?
Because of the risk of dropping the piston or hammer. One drop and they are scrap
،👍👍
Seeing how much things has degraded, when tools were built to last with less compunents, compared to the junk we're having this days. No rights to repair and made to break in few years. Manufacturers are Focused on performance than durability. 😢😢
That was a simple robust tool
Hi Dean - What is the grease you use which you apply with your paint brush?
Same thing i want to kno
Too many adds
That made in USA quality
