FAQ

Q1: How do I confirm this piston ring set is compatible with my specific Hino engine?
A1: The most reliable method is to cross-reference the part number currently on your engine or from your engine’s service manual with our listed OEM numbers (S1301-91610, S1304-E0320). Providing your engine model code and serial number to our technical team can also ensure a perfect match.

Q2: Should the cylinder liner be replaced or honed when installing new piston rings?
A2> For optimal performance and ring seating, the cylinder liner must be properly honed to achieve the correct crosshatch pattern. If the liner is worn beyond service limits, scored, or damaged, it must be replaced. New rings will not seal correctly in a worn or glazed cylinder.

Q3: What is the typical lead time for delivery to major ports in Europe or North America?
A3> For container or palletized B2B orders, standard sea freight to major ports like Rotterdam, Hamburg, Los Angeles, or Savannah typically takes 25-35 days. We also offer expedited air freight options for urgent requirements, with delivery often within 5-10 business days to main hubs.
