The E320C Adjust Pulley is a direct replacement component designed for Caterpillar excavator models equipped with the 3066 C6 undercarriage system. It is manufactured to match the original equipment dimensions, with a bore diameter of 65 mm and an outer flange width of 120 mm, compatible with standard 22 mm shafts. The pulley is constructed from ductile cast iron with a surface finish that resists abrasion from tracked undercarriage debris, ensuring durability in high-dust environments.
This pulley is typically used in excavators operating in mining, earthmoving, and infrastructure projects where belt tensioning and track alignment are critical. The material composition follows industry-standard ASTM A536 Grade 65-45-12 for ductile iron, which provides a balance of tensile strength and impact resistance. While the supplier does not specify heat treatment details, the pulley's design aligns with standard OEM tolerances for pulley runout, which should not exceed 0.15 mm for reliable belt tracking.
Buyers commonly source this part for repair fleets of Caterpillar E320C excavators in Southeast Asia, Africa, and Latin America. The pulley is supplied loose, without mounting hardware, and is packed in individual cardboard boxes with foam inserts to prevent surface damage during transit. Minimum order quantities are not stated and must be confirmed directly with the supplier. Trade terms are typically FOB Chengdu Port, with lead times averaging 15 to 25 days after order confirmation.

Before placing an order, confirm the exact excavator model and undercarriage serial number to ensure compatibility. Request a photo of the actual pulley being shipped, including close-ups of the bore, flange, and groove. Verify that the part number matches the supplier's listing and that there are no visible casting defects such as porosity or flash. Do not accept parts without clear identification markings.
Confirm the Incoterms with the supplier - FOB Chengdu is typical, but CIF or DDP may be available. Lead time is generally 15 to 25 days, but this can extend during Chinese holidays or port congestion. Payment terms are usually 30% advance, 70% against shipping documents. Request a commercial invoice with HS code 8431.49 for customs clearance. Ensure the packaging includes a packing list with part numbers and quantities.
Upon delivery, inspect for surface damage, verify dimensions with calipers, and check runout with a dial indicator. Test fit the pulley on the shaft before installation. Request a material test report if operating in extreme conditions. Retain all packaging and documentation for 90 days in case of warranty claims. For fleet operators, consider batch testing one unit before accepting full shipment.
