I had the joy of having to use one of these a long time ago. A heavy brut of a breaker to carry around but brilliant for breaking concrete. Only found you a couple of nights ago and I love how you explain everything you do. You have me hooked now 😂
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.
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 👍
I bought this Bosch Harbor Freight knock off 20 years ago, so reliable never needed service yet. I was much stronger 20 years ago, now a bit too heavy. Can't say much about Harbor Freight, lots of junk but this one is good.
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.
They still make an updated model not much has changed mechanically. I bought a Makita HR2470 SDS Drill for 100€ recently. It really surprised me how well made and durable they build it even just for a 100€ drill. Parts are available and cheap. Good stuff is still being made you just have to find it.
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.
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.
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.
@@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.
If it's stuck and you find a way to build air pressure behind it, you'll turn it into a rocket. Use grease gun pressure to move stuck things if you really have to, same way you remove stuck brake caliper pistons. A decent grease gun can build thousands of pounds of pressure, but grease isn't compressible so won't turn things in to a cannon
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. 😢😢
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
Tight initially, then starts sliding. Quote of the year.
LOL
As long as you use enough Grease 🎉

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!
Respect to the blokes who are lugging one of those around all Day!!
Feels like a feather compared to a air hammer.
I love that cronstruction yellow colour of the breaker. Takes me back to my childhood looking for Hymacs and JCBs.

You always explain everything so well! Thank you!
Love the comment about the “manliest cup ever” 😂

Keep up the great videos 👍
Now I want to buy one, just to make that Manly cup...cheers Dean! 🤔
More knowledge & great content as always looking forward to the next video to drop.
That's the first time I've seen a Bosch with Stanley yellow.
Sometimes I spend my Thursday night watching an Irish guy rebuild power tools on TH-cam and I’m okay with that
8:11 "Manliest cup ever!" Nice one Dean! 😄👍🏻👌🏻🛠️🔧🔩
4:21 the piston she told you not to worry about.
The manliest cup ever had me cackling 😂
Well done, nice video.👍👍👍👍👍👍

Got a bit of a workout with that one Dean
Holly...that's a big boy!
Very nice job Dean. Pretty sweet!!
When stuff was built with durability & repair in mind.

Ok, that piston is mental

Just had one in my shop. and it did say "Brute" on the black cowl ay the top. So you are right to call it a brute.
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.
that sounds better!!

What brand/type of grease are you using?
Great video, I’ve had mine, professionally rebuilt, and it still runs slow. Anyone have any idea?
12:29 That's what she said.
Great video!
Maybe you can recommend best garden tiller brand?
They were a great tool kango used to make a 2500 and a 1800 aswell

The lightest use to be. A machine mate.
Did you need to use any replacement parts? O-rings, etc.
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.
Isn‘t the chisel locking lever mounted different facing up when locked?
How come there’s no gasket or anything between the parts, wouldn’t leaks be inevitable?
The grease forms the seal
Omg hope there is no one downstairs 😮
A bosch tool needing a repair? That's new
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.
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
If it's stuck and you find a way to build air pressure behind it, you'll turn it into a rocket.
Use grease gun pressure to move stuck things if you really have to, same way you remove stuck brake caliper pistons.
A decent grease gun can build thousands of pounds of pressure, but grease isn't compressible so won't turn things in to a cannon
Just sold one of these £350 👍🏻
Seen smaller hammers on mini diggers.
Great job, great machine.
Nice one fella!!
What type is the brush on grease you use?
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

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
Hilti grease
،👍👍
Crikey. Ten minutes hanging on to that thing and say goodbye to your fillings,..😮
HIT THE LIKE BUTTON!!!
Dean is the Conor McGregor of repairs ❤
Nah mcgregors a scumbag
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
That's a small sledge for breaking concrete!!
@bushratbeachbum it might have been 12 lbs. It was 40 years ago
Too many adds
Didn't see one ad through the whole thing.
That made in USA quality
To German specifications.
