This new 2027 Peterbilt 567 conventional day cab is a 7-axle construction dump truck. It is set up for hauling construction materials in on/off-highway service. It carries a 20' Heritage Steel Smooth Side end dump body and has an 85,000 lb GVWR, a 348" wheelbase and a 261.8" cab-to-axle. The cab, hood and fenders are Fire Red in two-stage Axalta metallic/pearl paint, and the frame is black.

Engine & Drivetrain
Power comes from a 2024-emissions PACCAR MX-13 Performance engine rated at 510 HP at 1,600 RPM with 1,850 lb-ft of torque at 1,000 RPM, governed at 2,200 RPM. The engine is CARB emission compliant and CARB idling compliant, and the engine idle shutdown timer is disabled. It also has a PACCAR compression brake with controls on the right-hand column, engine monitoring protection with derate, and a powertrain optimized for performance at a typical operating speed of 65 MPH. The Allison 4500 RDS-P Gen 6 Rugged Duty Series transmission runs in a 6-speed configuration with a TC-571 torque converter and a dash-mounted push-button shifter. It shifts to neutral automatically when the parking brake is set and at stops. The main driveline is an 1810 HD with three midship bearings and 4.5" x .180 wall tubing, and a 1710 interaxle driveline serves the tandem. Rear axle ratio is 4.10. PTO equipment includes a dash-mounted single-acting electric-over-hydraulic PTO control, PTO mode control from the cab station, and a 12-pin remote PTO/throttle provision in the engine bay. Supporting equipment includes a PACCAR 160-amp brushed alternator, a PACCAR premium starter, three PACCAR premium 12V dual-purpose batteries (2,190 CCA) with a low voltage disconnect system, and a 110–120V immersion-type block heater. The cooling and air side has a high-efficiency cooling system, a 2-speed fan clutch for frequent start/stops and a WABCO 37.4 CFM air compressor. Fuel and intake filtration comes from an on-engine PACCAR fuel/water separator with an extended service interval, dual self-cleaning under-hood pre-cleaners and a firewall-mounted air cleaner. The exhaust is a dual SOC setup, with a left-hand SOC stack and the DPF/SCR in a single module under the cab on the right-hand side. It exits through a 36" chrome-plated steel standpipe with clear coat and a 45-degree cut curved tip.

Four Watson-Chalin SL10 self-steering pusher axles are rated at 10,000 lbs each, with dust shields, four air tanks, 8-stud iron hubs and cast drums. They are spaced 42", 84", 126" and 170" from the centerline of the forward drive axle. A crossmember-mounted lift axle regulator is controlled by a switch and gauge in the dash. Engineering-assigned ratings are a GVWR of 85,000 lbs, a front GAWR of 19,840 lbs, a rear GAWR of 23,000 lbs and a pusher axle rating of 9,880 lbs.

All axles use synthetic lubricant. The frame is 11-5/8" steel rails to 444" at 3/8" thickness, with a 10-3/4" x 3/8" full steel liner. The rails are zinc-coated and anti-corrosion treated, with aluminum crossmembers and heavy-duty iron front spring brackets. The end of frame is square and has two Holland TH-10050 tow hooks. Up front is a chromed, deep-tapered steel bumper with two tow points and a heavy-duty external tow eye. Maximum grade rating is 6%. The air system uses dual Bendix AD-IS air dryers with an EverFlow switching module and coalescing filters, steel painted air tanks with pull cords, nylon chassis hose, and body connections at 5' back of cab. A polished 26" aluminum 110-gallon fuel tank is mounted under the cab on the left, with a polished non-slip step and polished straps.
