The Yamaha XS650 XS motorcycle, introduced in 1978, was a popular model from Yamaha Motors, renowned for its balanced engine, efficient power delivery, and classic design. For those riders who opted for the convenience of an electric starter, the 306-15517-00-00 Idler Gear Shaft plays a crucial role in the successful engagement of the starter motor.
The Idler Gear Shaft, part number 306-15517-00-00, is a vital component of the electric starter system on the 1979 Yamaha XS650 XS motorcycle. This shaft transmission piece ensures efficient power transfer between the starter motor and the engine when starting the bike. Its primary function is to transmit the rotational motion of the starter motor to the engine while accommodating slight misalignment between the two components.
Constructed from robust materials such as steel, the Idler Gear Shaft offers durable performance and long-lasting reliability. The shaft presents a simple, cylindrical design with external threads on both ends. One end is intended to couple with the starter motor, while the other end interfaces with the engine driveshaft. Consequently, it is responsible for synchronizing the rotations of these counter-rotating shafts and enabling smooth engine engagement during starting.
Measuring approximately 358.5mm in length, the Idler Gear Shaft is an essential component that might wear down or become damaged through regular use. Identifiable by its resemblance to a long, thin rod with gearing on one or both ends, this part may exhibit symptoms of wear, such as increased starting resistance or failure to start altogether, necessitating a replacement.
