Thought this might be helpful to many -

When I was working for Cat dealer - turning pins and bushings - we had special wrench for the nuts for the pad bolts -- it was a "milled" slot at 90 degrees to the axis of the wrench.
1" drive rattle wrench on a cable with counterweight made handling the impact a one-handed operation.

Scarfing tip on the Victor Wrench took the frozen bolt heads off - careful with the torch and you can cut heads off without damaging the plates.

There was nothing easy about turning pins and bushings - dangerous and plain darn hard work! High pressures to push the "links" apart and heavy lifting of the components.
