Core Return Instructions and Important Notices
【Return Instructions】
- Drain all oil from the part.
Please make sure to completely drain any remaining oil before shipping the core. - Seal the part in a leak-proof plastic bag.
Since it is not possible to remove all the oil completely, please place the part securely in a sealable plastic bag to prevent oil leakage during transit.
【Important Notices】
- If the part contains more oil than allowed, it may be rejected during international shipping due to transport regulations.
- Oil leaks from the part can damage other packages shipped in the same container, potentially resulting in liability issues.
Please note that the customer is fully responsible for any problems caused by insufficient oil removal or improper packaging.
