( Manufacturer Part Number: 93310-216L2 ), ( Part Type: Bearing Piston Pin )
The Yamaha ET300 motorcycle, manufactured between 1979 and 1984, is known for its powerful and reliable engine. One of the essential components that ensure the engine's smooth operation is the piston wrist pin bearing (part number: 93310-216L2). This bearing allows the piston to rotate within the cylinder during engine operation while absorbing the load created by the connecting rod.
The 93310-216L2 piston wrist pin bearing from Yamaha is an OEM (Original Equipment Manufacturer) replacement part designed to provide the same level of performance and durability as the original component. It is made of high-quality materials that can withstand the extreme temperatures and high pressures inside a motorcycle engine.
This wrist pin bearing features a precision-machined interface that ensures a snug fit on the crankshaft and the piston pin. The bearing's outer diameter is 22.2 millimeters, and its inner diameter is 19.5 millimeters to accommodate the piston pin. The length of the bearing is 11.0 millimeters, providing ample support for the piston.
The bearing's design incorporates two full-circumference racing-style grooves on the outside that enhance grip and reduce the likelihood of the wrist pin coming loose under extreme conditions. This updated groove design provides improved engine performance, power delivery, and overall riding experience.
Moreover, the wrist pin bearing is lubricated using the engine oil to ensure the smooth operation of the piston during engine runtime. The bearing's material composition is engineered to have a low coefficient of friction, which reduces power loss due to mechanical wear and provides better fuel efficiency.
Replacing the worn-out piston wrist pin bearing with a genuine Yamaha 93310-216L2 part will not only restore the engine's performance but also safeguard it from potential catastrophic engine failure. Whenever installing this new bearing, refer to the service manual for proper procedures to ensure correct installation.
