The following information applies to automotive camshaft drives, distributor drives, or other underhood drives that may require synchronization. For other power transmission drives requiring synchronization, refer to Specifications for Drives using Synchronous Belts (MXL, XL, L, H, XH and XXH belt sections) (IP 24/1978), published jointly by the Rubber Manufacturers Association (RMA), the Mechanical Power Transmission Association (MPTA), and the Rubber Association of Canada (RAC).

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).
