Abstract: The invention comprises a belt installation tool comprising a substantially planar body. A belt engaging surface extends substantially normally from a portion of the planar body. A pulley engaging portion extends from the planar body approximately opposite the belt engaging surface. A central bore allows a tool to engage a pulley shaft. In use, the pulley engaging surface engages a pulley whereby the tool is rotated by a pulley rotation about a pulley axis, thereby causing the belt engaging surface to automatically urge a belt onto a pulley. The planar body stabilizes the tool against the pulley as a belt is installed. The molded body may be fabricated by injection molding.

Abstract: The invention comprises a tool for installing a low modulus type power transmission belt on an engine pulley. More particularly on a pulley having two sets of grooves whereby two power transmission belts are engaged with the pulley. The tool comprises a substantially semi-circular form having at least two surfaces engaged with a rim and which project radially therefrom. Each of the two surfaces also describe a helical angle with respect to an axis of rotation of the pulley. The first surface urges a belt into a first set of pulley grooves during a first tool rotation. The second surface urges the belt from the first set of pulley grooves to a second adjacent set of pulley grooves during a second rotation of the tool.
