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.

Abstract: An engine push rod holder of one piece of partially resilient material has a relatively thin, flat head from one edge or which a plurality of pairs of fingers extend in one direction. The fingers of each of the pairs have arcuate ends facing each other in the direction of the fingers and are deformable to snap around and closely engage a push rod.
