This is a Special Packaging Instruction (SPI) document for a Diesel Engine with National Stock Number 2815-01-580-5848, dated 7/9/2025, revision A. The document provides comprehensive, detailed instructions for the preservation, packaging, and shipping of a diesel engine (Caterpillar part number 2421356), including specific requirements for filter replacement, oil treatment, and protective measures to prevent corrosion during storage or transportation.

The packaging instructions specify a multi-step preservation process involving replacing fuel and oil filters, filling the crankcase with a VCI oil mixture, fogging intake and exhaust ports with preservative oil, cycling the engine using a starter motor, and carefully sealing and marking the shipping container. The document includes precise technical diagrams detailing the cradle assembly, blocking configurations, and hardware specifications, with requirements for using specific military standards (MIL-STD) for cleaning, drying, wrapping, cushioning, and marking the engine. The total unit pack weight is 2000 pounds, with dimensions of 55.0 x 46.0 x 57.7 inches, and the packaging is designed to protect the engine during long-term storage or shipment.
