Repairing an old, made in the USA, Bosch GSH 27 demolition breaker hammer. 

LOL

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.

Because of the risk of dropping the piston or hammer. One drop and they are scrap

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.

@@kevindavis7868 It’s an old transformer Dean uses it to test the hammer on a tool Better than knocking lumps out of the floor

Same thing i want to kno
