The following general information is web-sourced and may contain variances from the subject unit:
The 2009 Mack GU713 Granite is a high-spec, heavy-duty commercial workhorse explicitly customized for severe municipal snow-fighting and all-season utility.
Here is a comprehensive breakdown of the truck, its specialized mechanics, and its utility bodies:
1. The Pedigree: The Golden Mack Bulldog
On a Mack truck, the hood ornament isn't just decoration—it is a code for the drivetrain.
- The Gold Bulldog signifies that the truck features a 100% pure Mack integrated drivetrain. This means the engine (Mack MP7), transmission (Mack Maxitorque E5), and the drive axles were all manufactured internally by Mack Trucks. This full integration optimizes gear ratios and torque distribution specifically for heavy vocational duties.
2. Engine: Mack MP7 Diesel
- Type: 11-liter, 6-cylinder inline turbocharged diesel.
- Output: Depending on the exact fleet programming, it typically delivers between 325 to 405 Horsepower and up to 1,560 lb-ft of torque.
- Key Features: The MP7 uses an overhead camshaft design and high-pressure unit injection. It is engineered with a massive low-end torque curve, allowing the truck to push through heavy, wet drifts of snow from a dead stop without stalling out or bogging down.
- Performance: Known for high low-end torque, it provides the required muscle to push through massive snow drifts without stalling or straining.
Emissions Era: As a 2009 model-year engine, it utilizes an EGR (Exhaust Gas Recirculation) system and a DPF (Diesel Particulate Filter) to meet EPA regulations, notably operating without the need for DEF (Diesel Exhaust Fluid), which was introduced later in 2010.
3. Transmission: Mack Maxitorque ES (8-Speed w/ Lo & Lo-Lo)
- Model: Mack Maxitorque ES (often referred to as an "8LL" manual configuration).
- Gearing: It features 8 forward highway speeds, plus two ultra-low crawler gears ("Lo" and "Lo-Lo").
- Utility: The Lo and Lo-Lo gears provide extreme reduction ratios. This is critical when the truck is fully loaded with salt/sand and must crawl up steep, icy inclines, or pull out of soft ditches while running the heavy front and side plows.
- Triple-Countershaft Design: Mack's Maxitorque line uses a triple-countershaft design which splits the engine torque evenly into three paths, reducing stress on individual gear teeth and extending the transmission's lifespan.
4. Chassis & Wheels: 6×4 Tandem Axle
- Configuration: A 6×4 drivetrain means the truck has three axles total, with both rear tandem axles actively receiving power. This maximizes traction across slick winter surfaces.
- Tires: Heavy-duty 11R24.5 tires mounted on dual wheels on the rear axles. The 24.5-inch rim size provides excellent ground clearance, which helps prevent the undercarriage or plow mounts from bottoming out on packed snow banks.
5. Dump Body: Viking Cives 13' Pro-Line All Season (#PL1314SD)
- Design: Built by Viking Cives, a premier manufacturer of snow removal equipment.
- The "All Season" Advantage: This specialized body operates as a standard dump truck during summer construction, but converts seamlessly into a winter road-salting vehicle. Instead of tipping backwards to drop material, it can utilize an integrated conveyor/spreader system or a side-dump mechanism to cleanly feed material directly into the paths of the plows or distribution spinners.
6. Snowplows: 11' One-Way & 12' Wing
- 11-Foot Viking Cives One-Way Front Plow: This fixed-angle plow is tapered and shaped like a funnel. It is designed to scoop up snow at highway or municipal speeds and aggressively throw it far off to the right side of the road, clearing a wide path instantly.
- 12-Foot Side Wing Plow: Mounted to the right side of the truck chassis, this wing plow can be hydraulically extended outward. Used in tandem with the front plow, it allows the operator to clear up to 23 feet of roadway or highway shoulder in a single pass, vastly speeding up municipal clearing times.
