Core Policy

  • A refundable core deposit will be added to the invoice for all 3 and 4 cylinder remanufactured, replacement, repurposed engines and short blocks. Refunds will be subject to Yanmar’s inspection and approval.
  • The core engine (henceforth, in this document, the term “core engine” will also apply to short block core) returned must be the same/similar to the engine model purchased (like for like). The core must be assembled with all of the same components (fuel system, starter, turbo etc.) as supplied on the engine purchased.
  • The core engine must be in fully assembled condition with no visible or repaired cracks or holes in the block, head, or any other major component.
  • The crank must rotate 360° clockwise and counter clockwise with the original bearings installed or deductions may apply.
  • The core engine must be drained of fluid and all openings covered. Any penalties incurred from the shipping company resulting from damages and/or fines due to the core engine not being properly drained will be the responsibility of the shipper (dealer/distributor).
  • The core engine must be free from environmental wear such as corrosion, rust, fire and/or abuse.
  • Core engines must be returned to Yanmar America Corporation in the approved crate supplied with the engine or short block purchased within 60 days of the Mastry invoice date for credit.
