This innovative chaincase-less transmission system, introduced by Arctic Cat for snowmobiles, utilizes a system of gears and a drive belt to transfer power from the engine to the track. This design eliminates the traditional chain and sprockets found in most snowmobiles. A key feature is the constant velocity joint technology, which allows for smoother power delivery and reduced drivetrain friction.
The elimination of the chaincase reduces weight and maintenance requirements, contributing to a quieter and more efficient ride. This technology was a significant advancement in snowmobile drivetrain technology, offering improvements in performance, durability, and ease of use compared to previous systems. Its introduction marked a shift towards more sophisticated and integrated power transfer systems in the industry.
