1. Scope

This procedure covers the safe installation of belts on machinery, specifically focusing on alternator, fan, and air conditioning compressor belts. It applies to maintenance and repair activities in industrial settings where these components are used.

This procedure is applicable to environments where machinery with belt-driven components is operated and maintained. It should be used in conjunction with the manufacturer's operation and maintenance manuals.

2. Definitions

Belt
A loop of flexible material used to link two or more rotating shafts mechanically, most often parallel.

Tension
The state of being stretched tight, especially in the context of belts, to ensure proper operation.

Pulley
A wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt.
