Good To Know

Q: How many wrist pin bearings does one piston require? A: A single-cylinder engine like the Inviter 340 uses one wrist pin bearing per piston, so order one for each top-end rebuild.

Q: Should I replace the wrist pin bearing during a top-end rebuild? A: Yes, it is common practice to replace the wrist pin bearing whenever the piston or rings are serviced, since it wears along with those parts.

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