The laser alignment tool includes a laser beam emitter supported in a projector assembly which, when mounted on a precision alignment component, such as a pulley, is directed at a target assembly mounted on another precision alignment component. The plate of the target assembly against which the laser beam is directed is coated, textured or the like (e.g., has inscribed cross hairs) to produce a distinctive visual effect when struck by the laser with the precision alignment components in the correct or preselected alignment relative to one another. Moreover, if the precision alignment components are not in the correct or preselected alignment, impingement of the laser beam against the target plate does not produce the distinctive visual effect. The target plate may be contoured such that the distinctive visual effect indicates that the precision alignment components are in the correct or preselected alignment relative to one another in additional orientation planes.

[ What is claimed is:] [1.] A laser alignment tool for aligning precision alignment components in a preselected angular alignment relative to one another, said laser alignment tool comprising:projector and target members releasably mountable on respective ones of the precision alignment components in fixed annular orientations relative thereto;projector means including a laser beam emitter for emitting a laser beam having a longitudinal central axis defining a laser axis, said laser axis having a predetermined angular position with respect to said projector member corresponding to the preselected alignment; andtarget means including a target surface having a predetermined angular position with respect to said target member corresponding to the preselected angular alignment of the precision alignment components, said target surface being perpendicular to said laser axis when the alignment of the precision alignment components corresponds to the preselected angular alignment,said target means including indicia means on said target surface which, when the precision alignment components have the preselected angular alignment, produce a distinctive visual effect from impingement of the laser beam from said laser beam emitter against said target surface,wherein said target surface is contoured in a direction perpendicular thereto such that impingement of said laser beam against said target surface, when said laser axis is oblique thereto, causes deflection of said laser beam resulting in a second distinctive visual effect indicating angular displacement of the precision alignment components away from the preselected angular alignment.
