If anyone is interested, "the panther track is correctly adjusted when the track just touches the second bogie wheel from the front, ie, when further tensioning would lift it off this bogie wheel" ( Forty, George; "German Tanks of World War II ' In Action' ", London, Blanford Press, 1987 ).The quote is purported to be from a Wermacht file paper obtained by U.S Army intelligence in June 1944.To anyone with an interest in German tanks in ww2 i would highly recommend this book. It contains several photos of battle damage and other useful details.
i hope this will be useful to someone.
