CAUTION:
DO NOT use a number stamp or a punch to mark connecting rods, as damage to connecting rod may occur.
NOTE:
The use of a ink marker paint marker is acceptable for marking the connecting rods.
The pistons are a lightweight design with ultra low tension piston rings for improved fuel economy:
- The pistons are made of a high strength aluminum alloy and the piston skirt has a MolyT® coating.
- The top piston ring land has an anodized coating for improved wear performance.
- The piston is connected to the rod using a full floating pin with a locking clip on both sides.
- The connecting rod is powder-forged steel with a bolted cracked cap design. The connecting rod bolts are not reusable.
- Both compression rings have a TOP mark on the piston ring. The marked side of the ring must face the top of the piston.
