SAE J33:2009 download.Snowmobile Definitions and Nomenclature-General.
1. Scope and Purpose—This SAE Recommended Practice sets forth accepted definitions and terminology of maboc components and parts peculiar to snowmobiles.
Illustrations have been selected to identify functional characteristics and to identify common mechanisms. They are not intended to show all existing commercial machines or to be exactly descriptive of any particular machine. These criteria were prepared to facslitate clear understanding and promote uniformity in snowmobile nomenclature.
