Specs At A Glance

Q: Should I oil the bearing before installation? A: Yes, lubricate the bearing with fresh two-stroke oil before inserting the wrist pin. This ensures immediate lubrication during the initial engine startup.

Q: How do I know if this bearing is worn? A: Look for any side-to-side play or scoring on the rollers. A worn bearing will often produce a ticking or knocking sound near the cylinder head.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
