Claim:
1. In combination: a) first and second pulleys that are respectively mounted to turn around spaced first and second axes, each of the first and second pulleys having an outer circumference; b) an endless belt having a length, an inside surface and an outside surface; and c) a belt installation jig comprising: the belt installation jig and belt in an initial operating state with: i) the inside surface of the belt wrapped operatively against the outer circumference of the second pulley and partially operatively against the outer circumference of the first pulley; ii) the pulley pressing part urged against the outer circumference of the first pulley by the belt at a first circumferential location; iii) the belt residing between the belt pressing part and the outer circumference of the first pulley; and iv) the belt wrapped against the belt holding part at a second circumferential location spaced in a first circumferential direction from the first circumferential location so that the inside surface of the belt is spaced axially away from the outer circumference of the first pulley, the belt installation jig and belt configured so that with the belt installation jig and belt in the initial operating state, turning of the first pulley around the first axis in the first circumferential direction causes the belt installation jig to move: i) around the first axis so as to guide the inside surface of the belt fully operatively against the outer circumference of the first pulley; and ii) to a release location between the first and second pulley axes, the belt installation jig movable radially outwardly relative to the first pulley, the first pulley, belt installation jig and belt cooperating so that the belt confines radial movement of the belt installation jig relative to the first pulley as the belt installation jig moves from one location the belt installation jig resides at with the belt installation jig and belt in the initial operating state to the release location, the first pulley, belt installation jig, and belt cooperating so that the belt installation jig moves radially outwardly away from the pulley to be fully separated from the first pulley as an incident of the belt installation jig moving from the one location to the release location in response to turning of the first pulley around the first axis in the first direction.
