FAQ

What are the engine specifications of the 2015 MACK Granite GU813 Ready Mix Truck? +

The 2015 MACK Granite GU813 Ready Mix Truck is equipped with the Mack MP7-365C engine, a reliable 11-liter inline-six diesel engine. The MP7 engine family offers horsepower ratings from 325 to 405 HP with torque ranging from 1,200 to 1,560 lb-ft. The 365C designation indicates 365 horsepower. This lightweight engine is specifically designed for weight-sensitive applications, helping maximize payload capacity in ready-mix operations. The MP7 features a single overhead camshaft, ultra-high-pressure fuel injection system, and an electronically controlled Variable Geometry Turbocharger for optimal performance across all RPM ranges.

What is the mixing capacity and drum configuration of this unit? +

This unit features an 11-cubic-yard McNeilus drum mixer, which is a standard capacity for tri-axle ready-mix trucks. The McNeilus Standard Mixer is known for its robust construction, featuring a one-piece spun head design, 1/4-inch head thickness, and 3/16-inch skin thickness. The drum includes a 42-inch discharge opening and strategically positioned impellers for homogeneous mixing. The McNeilus design provides excellent concrete quality while maintaining durability and ease of maintenance.

What transmission does the 2015 MACK Granite GU813 Ready Mix Truck use and what are its benefits? +

The 2015 MACK Granite GU813 Ready Mix Truck is equipped with an Allison automatic transmission, likely a 6-speed model based on typical 2015 MACK Granite GU813 Ready Mix Truck configurations. Allison automatics are the preferred choice for concrete mixer trucks because they provide smooth shifting, eliminate clutch wear, reduce driver fatigue, and offer better control during slow-speed maneuvering at job sites. The automatic transmission is particularly valuable in stop-and-go ready-mix delivery routes and allows operators to focus on safe concrete delivery rather than manual gear shifting.

What is the axle configuration and weight capacity? +

The unit features a tri-axle configuration with a rear drop axle and double frame construction. The specifications indicate: front axle rated at 20,000 lbs, rear axles at 22,000 lbs each, plus a 13,500 lb drop axle. The Gross Vehicle Weight Rating (GVWR) is 77,500 lbs. The drop axle (also called a tag or pusher axle) can be raised when the truck is empty to reduce tire wear and improve fuel economy, and lowered when loaded to distribute weight and meet bridge law requirements. For complete specifications, visit the official 2015 MACK GRANITE GU813 product page from the manufacturer.

What is the mileage and hours on these units, and what does that mean for expected service life? +

The listing shows 62,300 miles with 13,700 engine hours. This represents relatively low usage for a 2015 model truck, averaging approximately 6,230 miles and 1,370 hours per year. The miles-to-hours ratio suggests the trucks spent time at job sites with the engine running but not traveling long distances, which is typical for concrete delivery. With proper maintenance, Mack MP7 engines can reliably achieve 500,000+ miles, meaning these units have substantial service life remaining. The one-owner history suggests consistent maintenance practices.

How does the 2015 MACK Granite GU813 Ready Mix Truck perform in concrete delivery applications? +

The 2015 MACK Granite GU813 Ready Mix Truck is specifically engineered for vocational applications like concrete delivery. The truck’s double frame construction provides the rigidity needed to handle the constant vibration and weight of a rotating drum. The tri-axle setup with drop axle offers excellent weight distribution for maintaining legal axle weights while maximizing payload. The Mack MP7 engine’s power-to-weight ratio allows the truck to navigate construction sites and residential streets while maintaining the drum rotation needed for concrete quality. The Allison automatic transmission excels in the stop-and-go nature of ready-mix delivery.

What are the fuel economy expectations for this truck configuration? +

Typical fuel economy for a Mack GU813 with an 11-yard mixer ranges from 4-6 miles per gallon, depending on route density, terrain, and driving conditions. The MP7 engine is designed with fuel efficiency in mind, featuring wave piston technology that improves fuel economy by 2% and reduces soot by 90% compared to standard pistons. Route density (number of stops per mile) has the biggest impact on fuel consumption, as the truck consumes fuel both while driving and while idling with the drum rotating at job sites.

Can this truck operate in all weather conditions and terrains? +

Yes, the Mack Granite is built for vocational service in varied conditions. The truck handles well in urban, suburban, and light off-road construction site conditions. For winter operations in northern climates, the truck can be equipped with engine block heaters, upgraded batteries, and other cold-weather packages. The McNeilus drum can be fitted with optional heated water systems to maintain proper concrete temperature in cold weather. The tri-axle configuration provides good traction, though chains may be required in severe winter conditions depending on local regulations.

What is the typical operational range before requiring refueling? +

The Mack GU813 typically has a fuel tank capacity of 90-100 gallons, though exact capacity can vary by configuration. With fuel economy around 4-6 mpg in concrete delivery service, expect an operational range of 360-600 miles per tank. However, in actual ready-mix operations, trucks rarely travel more than 50-100 miles in a work day due to the local nature of concrete delivery. Most operators refuel daily or every other day depending on route density and hours of operation.

What are the regular maintenance requirements for the 2015 MACK Granite GU813 Ready Mix Truck MP7 engine? +

The 2015 MACK Granite GU813 Ready Mix Truck MP7 engine features extended service intervals: 35,000 miles for highway applications or 15,000 miles/450 hours (whichever comes first) for vocational applications like concrete delivery. Regular maintenance includes oil and filter changes, fuel filter replacement, air filter service, DEF (Diesel Exhaust Fluid) system monitoring, and coolant system maintenance. The MP7’s design includes accessible service points for easier maintenance. Critical items include monitoring the SCR (Selective Catalytic Reduction) system, checking DPF (Diesel Particulate Filter) regeneration status, and inspecting turbocharger operation.

What are the primary wear items on the McNeilus drum and mixer system? +

Key wear components on the McNeilus drum include: drum interior fins (3/16-inch thick, which gradually wear from concrete abrasion), drum rollers and roller bearings, hydraulic pump and motor (typically Eaton 54 Series), discharge chute hinges and locks, water system valves and hoses, and the drum drive gearbox (often a ZF or PMP transmission). The fin design includes bolted surge fins that can be replaced individually rather than requiring a complete drum rebuild. Regular inspection of the hydraulic system prevents costly failures. Proper daily washing extends component life significantly.

What is the expected lifespan of major components of the 2015 MACK Granite GU813 Ready Mix Truck? +

With proper maintenance, the 2015 MACK Granite GU813 Ready Mix Truck MP7 engine can achieve 500,000-750,000 miles before requiring major overhaul. The Allison automatic transmission typically requires service at 300,000-500,000 miles. The McNeilus drum, with proper care and regular washing, can last 10-15+ years, though interior fins may require replacement every 5-8 years depending on concrete abrasiveness and volume processed. The hydraulic pump and motor typically last 8,000-12,000 hours before rebuild. Frame and suspension components can last the life of the truck with proper inspection and maintenance.

What CDL license is required to operate the 2015 MACK Granite GU813 Ready Mix Truck? +

Operating this truck requires a Commercial Driver’s License (CDL) Class B at minimum, as the GVWR exceeds 26,000 lbs. Some states may require Class A if pulling a trailer. Additionally, air brake endorsement is required. Some jurisdictions may require a tanker endorsement for the concrete mixer, though requirements vary by state. Operators should check their state’s specific CDL requirements. Many concrete companies provide additional in-house training specific to mixer operation, including drum control, concrete quality management, and jobsite safety procedures.

What are the dimensional considerations for transport and site access for the 2015 MACK Granite GU813 Ready Mix Truck? +

While exact dimensions vary slightly by mixer configuration, typical 2015 MACK Granite GU813 Ready Mix Truck measure approximately: 30-32 feet overall length, 8 feet width, and 12-13 feet height. Minimum turning radius is approximately 40-45 feet depending on wheelbase. Operators must verify job site access can accommodate these dimensions, including overhead clearance for power lines, bridge and underpass heights, and road weight limits. The tri-axle configuration provides good maneuverability for a truck of this size, but tight residential streets or narrow construction sites may present challenges.

What should buyers look for when purchasing a used 2015 MACK Granite GU813 Ready Mix Truck with this mileage? +

For a 2015 MACK Granite GU813 Ready Mix Truck unit with approximately 62,300 miles and 13,700 hours, verify the maintenance history including records of oil changes, PM services, and any repairs. Inspect the MP7 engine for common issues including injector condition, oil pressure sensor operation, and crankcase ventilation system function. Check the Allison transmission fluid condition and shift quality. Inspect the McNeilus drum interior for fin wear, check hydraulic system for leaks, verify drum rotation is smooth without binding, test all mixer controls and chute operation, inspect the water system for leaks, and examine the frame for cracks or damage. Request a diagnostic scan for any fault codes. Consider a pre-purchase inspection by a Mack-certified technician. The one-owner fleet history is positive, and 13 identical units being available suggests consistent specifications and maintenance practices.
