Thinking about a first drain of the new K 66 in the Husqy so surfed around and saw an interesting youtube by a gentleman in W Virginia. Very humble in his presentation with good pics of the internals, including the brake disc, magnets, etc, and a slow disassembly. His operating room is clean although not enclosed. I had hoped he would show us how he filled the two separate oil compartments and expansion tank, but he did not. Although Tuff Torque does publish a 3 page instruction for this, it could use a visual procedure. This seems like the kind of material suitable for a future forum. I am surprised more have not responded to your idea.
