Overview This used 2023 Peterbilt 579 day cab tractor was built for general freight and pulls a 53-foot van trailer. It has a 455 HP PACCAR MX-13 engine, a PACCAR TX-12 automated 12-speed transmission and a 186-inch wheelbase. It is rated at a 52,000 lb GVWR and an 80,000 lb gross combination weight, and was spec’d for 100 percent highway operation on grades up to 6 percent. The odometer read 393,530 miles at appraisal. The cab, hood, fenders, roof and bumper are finished in Axalta two-stage Yellow (P3308EY) over a black frame. Engine & Drivetrain The PACCAR MX-13 (2021 emissions) is rated at 455 HP at 1,600 RPM and 1,650 lb-ft of torque at 900 RPM, and is governed at 2,200 RPM. Its electronics run on the VMUX architecture. An MX compression brake is controlled from the right-hand column. The powertrain is optimized for fuel economy at cruise speed, with the effective road speed limit set at 65.0 MPH or greater and cruise control topping out at 75 MPH. Engine monitoring protection will derate the engine if a problem is detected. The engine idle shutdown timer is enabled with an ambient temperature override, and the truck meets CARB engine idling compliance. Driver Performance Assistant is enabled with driver coaching, anticipation score, brake saving score, tire pressure reminders and automated transmission reminders. Supporting equipment includes a PACCAR 160-amp brushed alternator and a PACCAR premium starter. Power comes from three PACCAR premium 12V dual-purpose batteries rated at 2,190 CCA, protected by a low-voltage disconnect system and a Kissling 300-amp battery disconnect switch on the battery box. Cooling is handled by a high-efficiency cooling system with a variable-speed direct-drive fan clutch. Air comes from a WABCO 25.9 CFM compressor. There is an engine-mounted PACCAR fuel/water separator with an extended service interval, a single engine-mounted air cleaner and a 110–120V immersion-type block heater. The exhaust is a single right-hand back-of-cab system with the DPF/SCR mounted right-hand under the cab, finished with a 24-inch, 5-inch-diameter chrome standpipe with a curved tip. The PACCAR TX-12 (PO-16F112C12) automated 12-speed transmission is shifted from a column-mounted right-hand shifter. It has economy shift calibration and neutral coast mode. The driveline uses an RPL20 interaxle and an RPL25 SD main driveline without a midship bearing. PTO readiness includes cab-station PTO mode control, a dash-mounted single-acting electric-over-air PTO control, and a 12-pin remote PTO/throttle provision in the engine bay. SmartLINQ remote diagnostics is also equipped. Chassis & Axles The frame uses 10-5/8-inch steel rails with a 5/16-inch rail thickness, aluminum crossmembers, and a tapered tractor end-of-frame with a crossmember and kingpin cutout. The 186-inch wheelbase pairs with a 117.8-inch cab-to-axle and a 173.8-inch cab-to-end-of-frame. Up front, a Meritor MFS+12E wide-track axle rated at 12,500 lbs with a 3.5-inch drop carries a 12,000 lb GAWR. Steering is a Sheppard HD94 power steering gear with a frame-mounted reservoir. In the rear, a PACCAR DX-40 tandem rated at 40,000 lbs runs a 2.85 ratio, with 20,000 lb GAWRs on each drive axle and synthetic lubricant in all axles. The truck has air disc brakes front and rear on PHP10 aluminum Preset+ hubs. The brake system includes Bendix ESP electronic stability with automatic traction control and 6S6M anti-lock brakes. An ISO 3731 trailer ABS power connector sits next to the J560 connector, and pin 7 of the J560 gets constant battery power. The air system includes a heated Bendix AD-HF air dryer with a coalescing filter, steel painted air tanks with pull cords, nylon chassis hose, and a self-returning dash-mounted brake hand valve. It also has 15-foot straight 3-in-1 air and electrical lines with two 7-way plugs. Fuel capacity totals 150 gallons from a 26-inch aluminum 100-gallon tank on the right and a 26-inch aluminum 50-gallon tank on the left. A 24-gallon DEF tank is mounted on the left, behind the fuel tank. Also on the chassis are an aluminum left-hand battery box with a polished non-slip step, a right-hand aluminum aftertreatment cab entry step, Hogebuilt 27-inch stainless steel quarter fenders and Peterbilt rear mudflaps. Suspension The front suspension uses taper leaf springs rated at 12,000 lbs with Tenneco shocks and 30mm spacer blocks. The rear runs a lightweight Peterbilt Low Air Leaf suspension rated at 40,000 lbs with 52-inch axle spacing. It has a dash-mounted dump switch with an indicator light and a suspension load air pressure readout in the digital cluster. The cab rides on its own air suspension. Cab & Interior The cab is a Peterbilt Aero 118-inch BBC aluminum day cab with a Metton hood and a thermal insulation package. Inside is a Prestige interior in Sterling Gray. The driver gets a Peterbilt ST air-ride high-back vinyl seat in black with a right-hand armrest, and the passenger side has a non-adjustable, non-air high-back vinyl seat with a toolbox underneath. The multi-function steering wheel has audio and cruise controls on a tilt/telescope column. A 15-inch digital cluster displays engine oil temperature, air filter restriction, brake application pressure, suspension air pressure, turbo boost and engine percent torque. Comfort and convenience features include a combination fresh-air heater and A/C, power door locks and windows, intermittent electric wipers, and a ConcertClass AM/FM/WB radio with 3.5mm aux, Bluetooth phone and audio, a USB port, and two speakers. The radio mutes when the transmission is in reverse. The cab also has RP1226 9-pin ELD telematics wiring provisions, an additional dash switch, a reconfigurable panel, auto-reset circuit protection, a fire extinguisher, a triangle reflector kit and a spare fifth key. Exterior features include a one-piece curved windshield, a three-piece fixed rear window, and a stainless steel outside sunvisor. The Peterbilt Aero mirrors are motorized and heated with integrated convex glass and body-color housings. There are also heated rectangular hood mirrors, a look-down mirror over the passenger door, a bright-finish hood air intake bezel, an under-cab air horn and a 107 dB backup alarm. The lighting package includes composite fender-mounted headlights with integral DRL, five LED aero marker lights, self-canceling turn signals, LED stop/turn/tail/backup lamps, and two flush-mounted LED load lights behind the cab. Body & Equipment This tractor is equipped with a Jost JSK37 fifth wheel top plate at a 7.6- to 8-inch height. It has a left-hand release on a Jost lightweight inboard slider with an 18-inch air slide and cab slide controls. A frame-mounted left-hand deck plate and access package makes hooking up easier.

The wheels are Alcoa ULT397 22.5 x 8.25 high-polish aluminum all around, and tire pressure is monitored by a SmarTire next-gen system.
