A1: We are specialized in the excavator engine spare parts, for example Main cylinder block, cylinder head, crankshaft, Engine assembly, piston, cylinder liner, piston ring, camshaft, connecting rod, oil pump, water pump, valve series products, movement, etc. almost all parts of the entire engine.
Q2: If I only know the excavator model, but can not offer parts No., what should I do?
A2: If possible, you can send us pictures of old products, name plate or the size for reference.
Q3: Can you accept sample order?
A3: Yes sure. We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.
Q4: Do you test all your goods before delivery?
A4: Yes, we have 100% test before delivery.
Q5: How can I do if there is something wrong with the items?
A5: Our products have been professionally tested and the quality is very stable. If you really found something wrong, please contacts. We have a professional after-sales team to help you solve the problem.
Q6: How do I know if my engine is a mechanical B3.3 or an electronic QSB3.3?
A6: Mainly by checking the fuel system. The B3.3 engine uses a mechanical in-line fuel injection pump and lacks ECM computer control; while the QSB3.3 uses a high-pressure common rail (HPCR) system, electronically controlled by an ECM.
Due to these structural differences, B3.3 engine repair components (such as pistons, cylinder head gaskets, repair kits, etc.) have significantly different compatibility with QSB3.3 components and are not interchangeable. Please provide the engine serial number (ESN) before ordering parts to ensure correct model matching.
