FAQ

Q1: How do I confirm this cylinder liner will fit my specific Komatsu engine?
A1: The primary fitment is confirmed by the OEM part number 6240-21-2220 and the engine model (6D170/SA6D170E/SAA6D170E). For absolute certainty, we recommend cross-referencing this number with your engine’s service manual or providing us with your equipment’s model and serial number for verification.

Q2: Is any machining required before installation of this liner?
A2: This is an OEM-size “drop-in” liner, meaning it is manufactured to the final finished dimensions. However, professional engine rebuild practice always involves checking the liner-to-block fit (interference fit) and performing final honing after installation to achieve the perfect piston ring seal. We recommend installation by a qualified technician.

Q3: What is included in the packaging, and what are the shipping terms?
A3: Each cylinder liner is individually packed in a plastic bag, placed in a protective box, and then secured in a export-grade carton. We ship worldwide under standard Incoterms (typically FOB, CIF, or EXW). Detailed quotes with shipping costs and lead times are provided based on your destination and order quantity.
