The ZD30 cylinder head is a direct replacement component for Nissan diesel engines used in commercial vehicles and light trucks. It is cast from high-silicon aluminum alloy, with intake and exhaust valve seats machined to match OEM specifications. The combustion chamber volume is 52.3 cc, and the valve angle is 28 degrees, matching the factory ZD30DDTi engine design. This head retains the original bolt pattern and camshaft bore alignment.
The component is designed for engines operating under sustained high-load conditions, with a compression ratio of 17.5:1. The valve guides are made of sintered iron with a chromium coating, and the valve seat inserts are made of martensitic stainless steel to resist erosion from exhaust gases. These material choices are standard in remanufactured cylinder heads for the Asia-Pacific aftermarket, where thermal cycling and sulfur content in fuel demand durability.
Buyers include diesel engine rebuilders, fleet maintenance providers, and aftermarket parts distributors in Southeast Asia, Africa, and the Middle East. The product is typically sold as a single unit or in batches of 2 to 10. Packaging includes anti-corrosion paper and a protective foam insert. Trade terms are FOB Chongqing, with lead times of 18 to 25 days. Minimum order quantity is not stated but is commonly 2 units for international shipments.

Chongqing Transfortune Invest & Consultant Co., Ltd. is a trading company based in Chongqing’s Hi-Tech District, specializing in automotive parts sourcing. The company does not list a manufacturing facility, and no production photos or equipment inventory are available. Its profile indicates it acts as an intermediary between overseas buyers and Chinese suppliers, with no verified factory audit or quality control certifications published.
The supplier has a 'harbor' trust tier and zero response rate, suggesting limited buyer engagement or responsiveness. The term 'imported' in its tier classification may reflect its role in sourcing from other manufacturers rather than producing in-house. Buyers should treat this as a distributor and request documentation directly from the actual manufacturer, if identifiable.

Before ordering, confirm the cylinder head is for the ZD30DDTi turbo variant and not the naturally aspirated version. Request a dimensional drawing showing combustion chamber volume, valve seat angles, and port dimensions. Verify that the head has been pressure tested for cracks using dye penetrant or helium leak testing. Retain the original head for comparison if replacing a failed unit.
Confirm Incoterms as FOB Chongqing and clarify whether the head is shipped in protective packaging with anti-rust coating. Lead time is typically 18 to 25 days, but ask if the head is remanufactured or newly cast. Payment terms are often 30% advance with balance against shipping documents. Avoid full prepayment without inspection rights or third-party certification.
Conduct a pre-shipment inspection for surface cracks, valve seat integrity, and bore tolerances. Use a straightedge to check warpage on the mating surface, and measure valve guide clearance with a micrometer. Request a certificate of conformity referencing the engine model and batch number. Keep a sample of the head’s casting number for future traceability in case of field failures.
