Peterbilt unveiled its all-new vocational Model 567 during the recent Mid-America Trucking Show, said to be the result of the most extensive product research and development in the company’s line-up.
At the core of the 567, says Peterbilt, is the new aluminum cab that meets severe-service requirements in standard trim. Strategically-placed steel reinforcements were designed to increase strength and optimize rigidity. For additional strength and cab stability, steel upper A-pillars and rear corner reinforcements were added. The large cast-aluminum front cab mounts distribute road stresses evenly, reducing road-induced wear and improving ride quality, Pete says.
The new Metton hood is said to be highly resilient, absorbing many impacts that would shatter or crack other materials. The hood pivot system has a protection feature that directs energy around the cooling module in the event of an impact.
The Model 567 is available in two BBC configurations – 121 and 115 in. – in a daycab or with a selection of detachable sleeper configurations in three sizes – 44, 70, and 80 in.
The 567 can be spec’d with a wide variety of heavy-duty components and in a number of configurations for increased payloads and optimized weight distribution. It’s available with a set-back front axle and with steer-axle ratings up to 22,000 lb. An angled steering-gear installation further improves maneuverability by increasing wheel cut by up to 9 degrees over other designs, reducing curb-to-curb turning diameter by up to 9 ft.
Pete says its “optimized” steering geometry reduces bump steer by up to 25%, minimizing steering wheel feedback over rough, uneven surfaces, and reducing driver fatigue.
The 567 is also available with single, tandem or tridem drive axles and a variety of lift axles. It’s standard with front air disc brakes and an electronic stability control system.
The 567 features a chassis that’s 10 to 15% stiffer than comparable products, says Pete, improving ride and handling while reducing in-cab noise. It was designed with service technicians and body manufacturers in mind. Chassis system routing improvements include new air and fuel hard lines and the separation of key air, fuel, diesel exhaust fluid, and electrical systems routings which are said to simplify service, repair, and body installation significantly.
The electrical system features angled dress covers, providing added protection for electrical connections, and several routing ‘troughs’ have been incorporated to define harness placements and ensure reliability.
Electric-over-air rocker switches enable valuable electronic interlocks and remove complex air plumbing from the dash.
The hood opens a full 90 degrees for easier access to key service points so technicians can reach the cab electrical and air connections, air intake filter, A/C service ports, and cab fresh air filter, which are all firewall-mounted for convenient access.
The 567 is available with the PACCAR MX-13 engine, in expanded power offerings up to 500 hp with 1850 lb ft of torque. The Cummins ISX15 is also offered, providing up to 600 hp for heavy-haul applications.
