Then turn the input shaft and count it's number of revolutions until the output shaft has made one complete turn...then do this for the other gears. Direct will be one full turn of the input equals one full turn on the output. If you have OD than about three quarters of a turn on the input shaft will equal one full turn on the output. Hope this make sense, Mike B  | | |
