The connecting rod for Caterpillar 320C excavator engines (S6K model) is a forged steel component designed to transfer combustion forces from the piston to the crankshaft. It is manufactured to replicate OEM dimensions and material properties, ensuring compatibility with the original engine design. The rod includes a precision-machined big end for the crankshaft bearing and a small end with bushing bore for the piston pin.
Forging material is typically high-strength low-alloy steel such as 42CrMo4 or equivalent, with a tensile strength of 900-1100 MPa. The big end is machined to a standard bore diameter of 80 mm with a tolerance of ±0.01 mm, and the small end bore is typically 32 mm. The rod weight is approximately 3.8 kg, matching factory specifications. Surface treatments include shot peening for fatigue resistance and chromate passivation to reduce corrosion.
These connecting rods are used in rebuilds of Caterpillar 320C excavators operating in mining, construction, and earthmoving applications. Buyers include equipment repair shops, fleet operators, and parts distributors serving Asia-Pacific markets. Trade terms are typically FOB Chengdu or CIF destination, with minimum order quantities confirmed directly. Packaging includes individual protective sleeves and wooden crates for long-distance transport.

Before ordering, verify the exact engine model and serial number compatibility, as Caterpillar 320C engines may have variations in connecting rod design across production years. Request a dimensional drawing or sample for comparison. Confirm the material grade and heat treatment process with a material test report. Do not rely on brand name alone for interchangeability.
Confirm Incoterms with the supplier - FOB Chengdu is common, but CIF or DDP may be available. Lead times are not stated and depend on production cycles; allow 4-8 weeks for new orders. Payment terms are typically T/T in advance or L/C. Always request a commercial invoice that lists the part number, weight, and packaging details exactly as shipped.
Perform visual inspection for surface cracks, especially around the big end fillet and bolt holes. Use a micrometer to verify bore diameters and a scale to check rod length. If available, request a magnetic particle inspection report. Retain a sample for future reference. Store rods in dry, temperature-controlled conditions to prevent corrosion before installation.
