The following information is intended as a guide to be used for evaluating belt construction, source approval, and quality audit. This recommendation has been prepared from existing literature, including standards, specifications, and data supplied by both producers and users. These recommendations cover drive layout details and V-belt testing methods, including test layout, pulley diameters, torque loads, and guidance for interpreting test data. The application of these automotive V-belts is to power engine or vehicle accessories that are physically attached to the engine.
The following information covers engine accessory drive layout details and testing methods and includes test configurations, pulley diameters, power loads, and guidance for interpreting test data. This information has been prepared from existing literature, including standards and data supplied by both producers and users of V-ribbed belts. When the engine is used to drive an external unit equipped with industrial type V-pulleys and belts, it is recommended that the power takeoff pulley on the engine be grooved according to the appropriate industrial standard. These standards are published by RMA-MPTA (Rubber Manufacturers Association - Mechanical Power Transmission Association); ISO (International Standards Organization) and ASAE (American Society of Agricultural Engineers).
