Piston And Connecting Rod
The reduced weight cast piston contains integrated valve reliefs in the piston crown. The pistons are made from high-temperature aluminum alloy equipped with three piston rings.
- First piston ring groove = square ring
- Second piston ring groove = taper face ring
- Third piston ring groove = three-part oil control ring
The forged steel connecting rod and cap is separated by the familiar "cracked" process. The connecting rod (large end) is angled at 30° allowing sufficient articulation in a very compact space. The pistons are cooled by oil jets spraying under the exhaust side of the piston crown.
