Peterbilt installs first MX-11 engine

Jan. 27, 2016
Goes into a Model 567 SFFA destined for ND contractor

Peterbilt Motors Co. installed its first MX-11 engine into a Model 567 set-forward front axle (SFFA) truck ordered by Knife River of Bismarck, ND; a 19-state full-service civil and residential contractor.

The OEM noted that truck is part of a 200 unit order by Knife River, which is an aggregate producer and supplier of asphalt, ready-mix concrete and other construction materials as well.

Introduced in October of last year, the 10.8-liter Paccar MX-11 engine became available for order via Peterbilt dealerships in November, with production beginning this week.

The six inline cylinder engine features a double overhead camshaft design, generates 430 hp and 1,550 lb.-ft. of torque, and uses compacted graphite iron (CGI) in both the engine block and cylinder head; a material  approximately 20% lighter and 75% stronger than traditional gray iron, Peterbilt said.

The OEM added that its new Model 567 SFFA is available in both 115- and 121-in. bumper-to-back-of-cab (BBC) lengths, with the 115-in. BBC offering a bumper-to-front-axle distance of 29 in., while the 121-in. BBC has a bumper-to-front-axle distance of 31 in. Peterbilt also offers the Model 567 in a set-back front axle configuration, also available in a 115- or 121-in. BBC length.
