The combination of: a) first and second spaced pulleys; b) an endless belt; and c) a belt installation jig having a body with: a pulley pressing part; a belt holding part; and a belt pressing part. The belt installation jig and belt cooperate so that with the belt operatively wrapped against the second pulley and partially operatively wrapped against the first pulley, turning of the first pulley causes the belt to progressively wrap around the first pulley to a fully operatively wrapped state, whereupon further turning of the first pulley situates the belt installation jig for separation from the belt and pulleys.

Installation devices, systems, methods of use, and methods of manufacture are described. An installation device that facilitates installing a toothed belt on a sprocket within a housing.

A belt tensioner for an engine accessory drive is installed over a pulley such that rollers extend toward the engine. Due the belt being between the tensioner and the engine, installation of the belt on the pulley is difficult. To simplify installation, a removable belt guide is included in the belt tensioner. Two methods of installing the belt and tensioner are envisioned. In a first method, the belt is first installed on the pulley and the belt guide holds the belt toward the pulley radially as the tensioner is installed over the pulley. In a second method, the belt is first installed to the tensioner and the guide holds the belt radially away from the pulley as the tensioner is installed over the pulley. In both methods, the belt guide is removed after the belt and tensioner are installed.

The present application relates to a belt assembly for a vehicle and an arrangement for a vehicle including the belt assembly. The belt assembly (2) comprises a belt body (20) having at least two ends, at least one of which is loop-free, wherein the belt body (20) is fixedly provided with a first attachment (21) at the at least one end, wherein the first attachment forms a step with respect to at least one side surface of the belt body at the respective end of the belt body, wherein the first attachment (21), together with the belt body (20), form a first mounting end (22) of the belt assembly. The belt assembly may have improved appearance and improved accuracy.
