Description
Yamaha Blaster OEM Transmission Bearing Kit
Rebuilding a Yamaha Blaster engine? This Yamaha Blaster transmission bearing kit includes the four genuine OEM bearings needed to support the transmission main shaft and countershaft.
Transmission bearings can develop wear, excessive clearance, noise, or roughness after years of operation. Replacing them while the engine cases are split helps restore proper shaft support and prevents worn bearings from compromising a freshly rebuilt engine.
Kit Includes
- Two genuine OEM Yamaha main shaft bearings
- Two genuine OEM Yamaha countershaft bearings
- Four transmission bearings total
Why Replace the Transmission Bearings?
The transmission shafts must remain properly supported and aligned for the gears and shift components to operate correctly. Worn or damaged bearings may contribute to excessive shaft movement, noise, rough rotation, and accelerated transmission wear.
Because these bearings require the crankcases to be separated for installation, replacing them during a complete bottom-end or transmission rebuild can prevent additional labor later.
Genuine OEM Yamaha Quality
This kit uses genuine Yamaha bearings selected for the proper dimensions, fit, and application. It is a dependable choice for professional engine builders and customers who want OEM-quality components inside their Yamaha Blaster engine.
