A belt installation tool (100) for installing a belt without rotating the pulley (P) or the tool about a pulley axis of rotation. The tool comprises a ramp (11) that engages a pulley flange (F). The ramp (11) comprises a connecting member for connecting the ramp (11) to the flange (F). After the ramp is connected to a pulley flange a belt is loosely engaged with the ramp. A first lever arm (10) connected to the ramp is used to pry the ramp and belt outward by pivoting about the first connecting member until a second connecting member is engaged with the pulley flange. The ramp further comprises a member for laterally urging the belt. Once the ramp is fixed on the pulley flange a second lever arm (20), connected at a pivot point, urges the belt laterally onto the pulley. The second lever arm (20) is moveable in a direction normal to the movement of the first lever arm, thereby laterally urging the belt onto a pulley.
