Kimpex Needle Bearing for Yamaha Enticer 340 1978-1988 294848

Needle bearing wear is one of the most common causes of Yamaha Enticer 340 engine failure, particularly in the crankshaft and transmission assemblies. This OEM-spec Kimpex replacement bearing restores precision fit and eliminates excess clearance that leads to increased friction, heat buildup, and premature component degradation. Whether you're rebuilding a vintage sled or performing scheduled maintenance, this bearing delivers the durability and tight tolerances your engine demands.

Manufactured from premium bearing steel and subjected to rigorous heat treatment, this needle bearing is engineered to handle the sustained high-RPM loads of vintage snowmobile engines without compromise. The carbon nitriding process creates a wear-resistant surface that extends bearing life significantly compared to standard replacements, while precision grinding ensures minimal heat generation during operation.
