BLUF: Label shipping containers correctly when turning obsolete M113-series FOV’s heater box engines into the supply system to avoid confusion and costly repair depot delays.
Units, after converting an M113-series vehicle’s obsolete heater box-equipped engine, NSN 2815-01-248-7644, to the new glow plug engine, NSN 2815-01-412-2715, be sure to correctly label the shipping container before turning the heater box engine back into the supply system.
The tendency is to place the heater box engine into the empty glow plug engine container and then fail to relabel it. Heater box engines in shipping containers marked as containing glow plug engines confuse the supply system. These mismarked containers can mistakenly end up at repair depots where M113-series vehicles are awaiting new engines. The repair depots must then convert the old engines to the glow plug version before they can be placed into vehicles, costing the depots both time and money.
Help avoid confusion and costly delays when turning in unserviceable heater box engines by clearly making the shipping containers as “Heater Box Engine, NSN 2815-01-248-7644."
