Connecting Rod: Description and Operation

DESCRIPTION

CAUTION: DO NOT STAMP the connecting rods during identification. The use of a scribe or a paint mark is acceptable.

NOTE: The connecting rods in this engine are a cracked cap design. The cracked cap design is easily identified by the connecting rod cap bolts rather than the traditional forged connecting rod cap nuts. The connecting rod caps must be paint marked or scribed to identify the accompanying connecting rod. Connecting rod caps ARE NOT interchangeable between connecting rods.

The pistons are made of cast aluminum alloy and are a strutless, short skirt design. The piston rings consist of two compression rings and a three piece oil ring. Piston pins connect the piston to the forged steel connecting rods. The piston pins are a press fit into the connecting rod small bore. The piston, pin and connecting rod are serviced as an assembly.
