ABSTRACT:
A system for measured tightening of an oil filter to an engine block mount includes an array of clocks placed circumferential around oil filter (20). Each clock has one dark hand (26) and one light hand (28). The light hand is advanced of the dark hand. The degree of tightening is determined by amount of separation between hands. As filter is rotated, next clock coming into view, has hands positioned one hour advanced (4-13). Panoramic movement of hands as filter is turned will indicate degree of rotation and tightening.
