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.

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.

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 👍

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.

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.

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. 😢😢
