Identification
How to identify your DD16
Read us the engine serial number from the block stamp or engine label. It is also stored in the MCM. DD16 serial numbers are commonly reported to start with 473.
Because the DD16 is often in severe-duty trucks, the rating and the truck's cooling and PTO setup matter. Give us the truck VIN along with the serial number.
- Engine serial number
- Truck VIN, year and model
- Horsepower and torque rating
- Transmission and PTO setup
01DD16 vs DD15
The DD16 is a larger-displacement engine than the DD15 with higher torque ratings. It is not a DD15 with a different calibration; the block and internals differ. Heavy-haul trucks spec'd with a DD16 also tend to have larger cooling packages and heavier drivetrains, so match the engine to the truck.
02Turbo-compound and high-value parts
Many DD16 engines use a turbo-compound unit, and all use expensive turbo and EGR hardware. Ask what is included and whether those parts came off the same engine.
03Severe-duty history
DD16 engines often spend their lives at high load: heavy haul, logging, oilfield. Mileage alone does not tell the whole story. Ask about the donor truck's application and whether hours are available from the MCM.
