Piston: Description and Operation

ROD-PISTON & CONNECTING





The pistons (1) are made of a high strength aluminum alloy with an anodized top ring groove. Piston skirts are coated with a solid lubricant for scuff resistance. The pistons have an F cast into the side next to the pin bore that must face towards the front of the engine. The connecting rods are made of powdered metal with a fractured cap design. The connecting rod attaches to the piston with a full floating pin retained by lock rings. The piston and connecting rod are serviced as an assembly.
