Good To Know
Q: Does this bearing require pre-lubrication? A: Yes, always coat the needle bearings in clean two-stroke oil before assembly to prevent initial start-up wear.
Q: Can this be reused during a piston change? A: No, it is standard practice to install a new bearing whenever the piston or wrist pin is serviced.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
