Piston: Description and Operation
Piston and Connecting Rod Assemblies
The cast aluminum pistons use two compression rings and one oil control assembly. The piston is a low friction, light weight design with a flat top and
barrel shaped skirt. The piston pins are offset 0.9 mm (0.0354 in) toward the major thrust side (right side) to reduce piston slap as the connecting rod
travels from one side of the piston to the other side after a stroke. They have a floating fit in the piston and are retained by a press fit in the connecting
rod. The connecting rods are forged steel. The connecting rods are machined with the rod cap installed for proper clearances and alignments.
