ABSTRACT:
A positioner for use in removing from or installing camshaft bushings in a camshaft alley of an engine employing a camshaft extending along an axis and having a front planar face normal to the axis includes a yoke removably secured to the engine front face. A bar is supported by the yoke in place of the removed engine camshaft. A motor interconnects the yoke and the bar for relative axial motion. Bushing-engaging sleeves removably lock axially around and onto the bar at locations axially spaced to abut the ends of the bushings at the various locations of the engine camshaft bushings.
