FAQ

Q: Is this cylinder block a direct bolt-on replacement for my Komatsu PC400-7?
A: Yes, this part (6154-21-1100) is designed to be a direct OEM-size replacement for the 6D125-3E engine in the PC400-7. However, we always recommend comparing the casting numbers and physical dimensions of your existing block with the product specifications to confirm compatibility, especially if your machine has undergone previous major repairs.

Q: What is the typical lead time for shipping this heavy part internationally?
A: Lead times vary by destination and shipping method. For sea freight (the most economical option for a 300kg cylinder block), delivery to major ports typically takes 25-35 days. For urgent orders, air freight can reduce this to 5-10 days. Please contact our sales team for a precise quote based on your location and preferred shipping method.

Q: What maintenance steps should be taken during installation?
A: Proper installation is critical. Ensure the block is clean and all oil passages are free of debris. Use new OEM-spec gaskets and seals. Torque all main bearing cap and cylinder head bolts to the manufacturer’s specifications in the correct sequence. It is also highly recommended to have the cylinder block inspected by a qualified machine shop before installation to verify flatness and bore condition.
