Piston: Description and Operation

DESCRIPTION





The pistons 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 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 (Fig. 64).

OPERATION
The piston and connecting rod is the link between the combustion force to the crankshaft.
