Abstract
A method of determining backlash wherein one member of a gearset is rotated in a first direction and rotary positions are recorded at predetermined increments. The rotary positions of the other member of the gearset are recorded simultaneously with those of the one member. The direction of rotation of the one member is reversed and rotary positions are recorded at the same increments while simultaneously recording the rotary positions of the other member. The difference in recorded positions for the other member are calculated thus representing the amount of gearset backlash.
