FAQQ1: Are your products OEM or aftermarket? How do you ensure quality?A: We supply high-quality aftermarket replacement parts, covering a wide range of engine components including crankshafts, camshafts, cylinder blocks, cylinder heads, connecting rods, bearings, and various other engine parts. All products are manufactured to meet or exceed original (OEM) specifications.We use premium materials (such as nodular cast iron, forged steel, alloy cast iron, etc.) combined with precision CNC machining processes. Every product undergoes strict inspection procedures before shipment, with testing standards tailored to different product types:1. Moving Parts (Crankshafts, Camshafts, Connecting Rods): 100% Magnetic Particle Inspection (MPI) for crack detection, CMM dimensional inspection, dynamic balancing test (for crankshafts), or cam profile measurement (for camshafts).
2. Structural Parts (Cylinder Blocks, Cylinder Heads): 100% pressure testing, dimensional inspection, material hardness testing.
3. Precision Fit Parts (Bearings, Pistons): 100% dimensional sorting, surface roughness inspection
We can provide Material Test Certificates, Inspection Reports, and batch traceability information upon request.Q2: How can I confirm that your products match my engine?A: To ensure accurate matching, please provide any of the following information:OEM Part Number: This is the most accurate method and applies to all product types.
Engine Model: e.g., Mitsubishi 6D22, Hino J08E, Cummins 6BT, etc. From the engine model, we can query the complete parts list.
Vehicle Chassis Number / VIN: The VIN allows precise matching to the specific model year.
Key Dimensions:1. For Crankshafts/Camshafts: Main journal diameter, crankpin diameter, overall length, number of cylinders.
2. For Cylinder Blocks/Cylinder Heads: Bore diameter, bolt hole positions, casting numbers.
3. For Other Components: Any markings or numbers on the original part, or measurable key dimensions
We have an extensive engine database and a professional technical team to assist with cross-referencing, ensuring perfect compatibility. If in doubt, feel free to provide photos of your original parts, and we will verify for you free of charge.Q3: Are your products traceable? How can I track the production batch?A: Yes, we implement a strict product traceability system. Every engine component leaving our factory bears a unique production batch number or traceability code, typically stamped, laser-marked, or labeled on a non-working surface.
If you encounter any issues during use, simply provide the batch number information from the product, and we can retrieve the complete production archive for analysis within 24-72 hours. This end-to-end traceability is a vital component of our quality system and provides you with maximum procurement security.

Q4: What is the Minimum Order Quantity (MOQ)?
A: As a B2B supplier, we offer flexible MOQ policies:
1. Standard Models: MOQ is typically 5-10 pieces , depending on product type, model, and stock availability.
Fast-moving / Stock Items: Mixed orders are accepted, combining different part numbers to meet the MOQ.

Please contact our sales team for MOQ details on specific products.shipment.Q5: How do you package engine components to ensure safe sea transportation? A: We employ differentiated export-grade professional packaging solutions based on product characteristics to ensure your goods arrive intact. For long shaft products such as crankshafts and camshafts, we wrap all machined surfaces with eco-friendly recyclable packaging bags, and for working surfaces requiring extra protection, we add a protective mesh sleeve over the bag before placing the product into its inner packaging, and then into reinforced wooden cases. For housing parts like cylinder blocks and cylinder heads, we apply rust prevention treatment, secure them to wooden pallets with steel strapping, and add corner protection. For precision small parts such as bearings, pistons, and valves, we use individual packaging with rust preventive oil and paper, employ internal dividers to prevent collision, and pack them in high-strength export-grade cartons. For large assemblies like complete engines, we use vacuum moisture barriers, mount them on brackets, and pack them in fumigated wooden cases.
All outer packages are clearly labeled with part numbers, quantities, gross weights, and dimensions, along with appropriate handling warnings such as "Fragile," "This Side Up," and "Keep Dry" based on product characteristics. We can provide photos of the packed goods for your confirmation before shipment.Q6: What is your process for handling quality issues upon arrival?A: We have a clear and efficient after-sales support process:1.
