Piston Pin: Inspection

Measure piston pin diameter, piston bore and connecting rod bores. Replace components if not within specification. See CYLINDER , PISTON & ROD SPECIFICATIONS table.

NOTE: Rod must be positioned on the piston so the oil squirt hole faces the camshaft side of the engine when piston is installed with arrow toward the front of the engine.
