Note direction of connecting rod installation on piston before removal. Connecting rod must be installed in original direction.
- Piston pin is full floating in piston and is an interference fit in rod. Pistons and rods are weight matched for balance. DO NOT switch pistons with other rods. Piston and rod assemblies are serviced as an assembly for balance. Other information for connecting rod-to-piston installation is not available from manufacturer.
