[AT] Hydraulic cylinder rebuild.

[Cecil Bearden]

Yep!  There is a guy in the Frozen North who runs Cats.  I got the idea 
from one of his postings.  Since I got Autocad, it is so easy to draw 
wrench patterns.  I don't know about the torque, but when I tightened 
the nut, I bent a tempered steel round and square 6"pry bar my 
Grandfather had from the 1800's.
