I think this is exactly what Andy is talking about with 
alignment problems and the need for a self aligning 
coupler or whatever it was. (stinkin CRS!)

In all the years I worked drill rigs, earthmoving 
equipment and the like I've never seen a hydraulic 
component  mounted truly solidly, they're always 
mounted with room for adjustment and some slack.

The self contained hammers take care of the problem by 
using the piston and cylinder as the guides. The ones 
I've taken a look at anyway. There are square cylinder 
rams available so it might be a possible solution for a 
modern utility hammer.

How was it taken care of in the age of steam? Were they 
so large it wasn't a factor? Different coupling system? 
. . . ?

Hmmmmm.
