Rod, Piston And Connecting: Description
Do not use a metal stamp to mark connecting rods as damage may result, instead use ink or a scratch awl.
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 Moly® 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 two locking clips. The connecting rod is powder-forged steel with a bolted cracked cap design. The connecting rod bolts are not reusable. Pistons are available in three diameters (A, B and C) with grade markings for each bore indicated on the side of the cylinder block. The upper compression ring is a 1.2 mm steel ring with PVD coating. The intermediate compression ring is 1.2 mm micro napier design. Both compression rings have a dot or a mark on the piston ring. The marked side of the ring must face the top of the piston. The 2 mm three piece oil control ring is very thin. Both the rail segments and the expander are nitride steel.
