Overview

Overview
This 2027 Peterbilt 567 conventional day cab is set up as a 7-axle construction material hauler for hauling construction materials on and off the highway. It pairs a 21' Heritage Aluminum Material Hauler body with a heavy-spec chassis that runs four self-steering pusher axles ahead of a tandem drive. The cab, hood, and fenders are finished in Gunmetal metallic paint.

Engine & Drivetrain
A PACCAR MX-13 Performance engine powers this truck, rated at 510 HP at 1,600 RPM and 1,850 lb-ft of torque at 1,000 RPM, governed at 2,200 RPM. The engine meets 2024 emissions standards and is CARB emission and idling compliant. The powertrain is optimized for performance in vocational applications, with a typical operating speed of 65 MPH. It runs on EMUX electronics architecture and includes engine monitoring protection with derate. A PACCAR compression brake is controlled from the right-hand column. A cab-station PTO mode control and a 12-pin remote PTO/throttle provision in the engine bay are included.

Power goes through an Allison 4500 RDS-P Gen 6 Rugged Duty Series automatic transmission in a 6-speed configuration. The transmission uses a TC-571 torque converter and a dash-mounted push-button shifter. Auto neutral engages with the parking brake, and the transmission also goes to neutral at a stop. The driveline is a Spicer SPL250 Lite with three midship bearings and an SPL170 XL interaxle shaft. A dash-mounted single-acting electric-over-hydraulic PTO control is included. Rear axle ratio is 4.10.

The electrical system includes a PACCAR 160-amp brushed alternator and a PACCAR premium starter. Three PACCAR premium 12V dual-purpose batteries supply 2,190 CCA. There is a cab power disconnect switch beside the driver’s seat and a low voltage disconnect system. A 110–120V immersion block heater is fitted.

Cooling is handled by a high-efficiency cooling system with a 2-speed fan clutch suited to frequent start/stop work. Intake uses dual under-hood self-cleaning pre-cleaners and a firewall-mounted air cleaner. Fuel filtration is a PACCAR fuel/water separator with an extended service interval. Air is supplied by a WABCO 37.4 CFM compressor.

Exhaust uses a dual SOC layout. The single-module DPF/SCR sits right-hand under cab, and a left-hand 36" chrome standpipe is upgraded to 7" chrome-plated steel with a 45-degree cut curved tip.

Chassis & Axles
The frame uses 11-5/8" steel rails at 3/8" thickness on a 348" wheelbase, with rails running to 444". A 10-3/4" x 3/8" full steel inner liner reinforces the rails. The rails are zinc-coated and anti-corrosion treated. Crossmembers are aluminum, with heavy-duty iron front spring brackets and a square end of frame with a steel crossmember. Two Holland TH-10050 tow hooks are mounted at the end of frame. Cab-to-axle measures 261.8" and cab-to-end-of-frame measures 317.5".

The front axle is a PACCAR FX-20 wide-track steer axle rated at 20,000 lbs with a 4" drop. Steering is a Sheppard HD94 dual-gear power steering system with a frame-mounted reservoir and cooler.

The rear axle is a Dana Spicer D46-172 tandem rated at 46,000 lbs. It has heavy-wall drive axles and tandem differential locks with speed interlock. Synthetic lubricant is used in all axles.

Four Watson-Chalin SL10 self-steering pusher axles are fitted, each rated at 10,000 lbs with dust shields and four additional air tanks. They are spaced 42", 84", 126", and 170" from the forward drive axle. A crossmember-mounted lift axle regulator is controlled by a dash switch and gauge. All four pusher axle pressures display in the digital cluster.

GVWR and GCW are both 85,000 lbs. GAWR is 18,740 lbs front, 9,880 lbs first intermediate, 23,000 lbs second intermediate, and 23,000 lbs rear. Maximum grade rating is 6%.

Air disc brakes are fitted on the steer axle and the tandem drive. These use PHP10 iron Preset+ hubs and severe-service disc rotors. The pusher axles use 8-stud iron hubs with cast drums. The braking system also includes Bendix Smart ATC traction control, 6S6M ABS with an off-road ABS switch, an SBM valve, a pneumatic park brake, and a tire pressure monitoring system.

The air system uses dual Bendix AD-IS air dryers with an EverFlow switching module and coalescing filters. Air tanks are painted steel with pull cords on every tank, and chassis hose is nylon. Body air connections are provided 5' behind the cab.

A 26" polished aluminum 110-gallon fuel tank is mounted left-hand under the cab, with a polished non-slip step and polished straps. The DEF tank sits left-hand behind the cab under a polished stainless cover. A polished aluminum battery box sits above the rails behind the cab. On the right-hand side, an aluminum non-slip cab entry step is mounted on the aftertreatment. Up front, a chromed deep-tapered steel bumper with two tow points and a heavy-duty external tow eye complete the front end.

Suspension
The rear suspension is a Hendrickson HMX EX 460 HAULMAAX rated at 46,000 lbs, with a 54" axle spread and a 70K creep rating. It has dedicated shock absorbers. Up front, 20,000 lb taper leaf springs are paired with Tenneco shocks, greasable spring pins, and 80mm spacer blocks.
