Review YAMAHA Oem 2nd Gear Pinion 14t fits YFZ 450 2004–2013

The Yamaha YFZ 450, produced between the years 2004 and 2013, is a popular all-terrain vehicle (ATV) known for its power and agility. One essential component of this machine is the 2nd gear pinion, which is an integral part of the transmission system. The pinion gear, specifically a 14-tooth model identified as part number 5TG-17121-00-00, plays a vital role in transferring power from the engine to the drive wheels during the second gear engagement.

This 14-tooth 2nd gear pinion is meticulously crafted by Yamaha to ensure optimal performance and durability. It is manufactured using high-strength steel, which provides robustness against wear and tear, enabling the ATV to handle various terrain conditions with ease. The precision-machined teeth ensure smooth power transfer, contributing to a responsive and efficient driving experience.

The 5TG-17121-00-00 pinion gear is designed to fit perfectly with other transmission components in the Yamaha YFZ 450. The tooth profile and pitch are engineered to work harmoniously with the corresponding gear in the transmission, ensuring a reliable and efficient power transfer. The pinion gear's dimensions are carefully measured to ensure precise alignment with the drive shaft and other transmission components, ensuring a secure and snug fit.

When it comes to maintenance, the 14-tooth 2nd gear pinion is relatively easy to access and replace, making it a popular component for upgrades and repairs. However, it is recommended to follow the manufacturer's instructions carefully when performing any maintenance or replacement tasks to ensure the longevity and performance of the Yamaha YFZ 450 ATV.

In summary, the 5TG-17121-00-00 14-tooth 2nd gear pinion is a crucial component of the Yamaha YFZ 450 all-terrain vehicle, responsible for transferring power from the engine to the drive wheels during second gear engagement. This high-strength steel pinion gear is meticulously engineered to ensure smooth power transfer and durability, contributing to the vehicle's overall performance and reliability.
