The oil filter for Honda GX630 engines is typically Honda part number 15410-ZE3-000, though revisions across model years and configurations can change the exact PN. Always verify against your engine’s serial number and the latest Honda Power Equipment Parts Catalog (2024–2026 editions) before purchasing.
Understanding GX630 variants and PN accuracy
Why numbers differ by version
Honda's GX630 has been used in multiple formats—industrial engines, portable generators, and marine applications—over many years. Each variant can use a slightly different filter element or housing, which means the part number can vary even for the same model name.
To ensure you buy the correct filter, use the following checklist and consult the official diagram for your exact unit.
- Know your engine’s model and serial number from the data plate on the engine.
- Look up the GX630 parts diagram for your exact model/year, which shows the correct oil filter PN.
- Check if your unit is configured as a standard industrial GX630, a generator version, or a marine variant, as this can affect the PN.
By matching your serial/model and the official diagram, you reduce the chance of ordering the wrong part.
