Bertha and rocktoy have it all covered. When I did mine, I took pictures and labeled the shit out of everything. Then I proceeded to start taking off every nut and bolt and putting them into many big coffee cans, all labeled for each part, etc. Then I ran out of cash and it sat for a year and a half before I got the machine work done. Then it was all a blur...Anyway moral of the story, if your going to rebuild it, have all the $$ on hand, makes it easier come reassembly.
