MACK Pinnacle Service Manual

MACK PINNACLE

CONQUER THE ENDLESS HIGHWAY

The Mack® Pinnacle™ represents the best in truck engineering. From a lightweight-yet-strong frame specially designed for heavy loads, steep grades

™

and long hauls to a powerful and fuel-efﬁcient MP

engine that delivers the brawn you need to maximize payload, this tractor is built to boost proﬁts.

BUILT TO FIT THE WAY YOU WORK

From our popular DayCab model to an army of sleepers, the Mack® Pinnacle™ offers a comfort level that ﬁts every type of driver. Our DayCab is best suited for local trips while our 48- and 56-inch ﬂat-top sleeper models are ideal for overnight hauls or day trips with long waits. Our 60- and 70-inch mid-rise sleepers are ideal for regional hauling. The 70-inch high-rise sleeper is spacious, features plenty of headroom and helps drivers make long-distance runs comfortably. All of our sleeper models are loaded with amenities to make life on the road easier.

The Pinnacle tractor in an axle back conﬁguration (shown this page) boasts sleek lines that look good and improve aerodynamics. And the axle positioning delivers maximum maneuverability as the front axles are set back on the frame to improve the turning radius.

DURABLE HEADLIGHTS: The LEXAN

resistant and offer easy access for replacing bulbs without a single tool.

VERSATILE BUMPER: The durable bumper is designed with dual tow

clevises, and is also equipped with fog lights for better visibility in inclement weather.

SPLASH SHIELDS: Hood splash shields keep the engine compartment

clean extending component life, and they lift with the hood to create more room for vehicle maintenance and service.

DURABLE HOOD: Hood isolators allow the hood to ﬂex independently

from the cab for increased durability over rough terrain.

GALVANIZED STEEL CAB: Pinnacle’s durable galvanized steel cab is

mounted on airbags and shocks and stabilized with sway bars, so while the truck soaks up the rough stuff, the driver stays comfortable, rested and productive.

RUBBER-SEALED WINDSHIELD: A two-piece windshield is isolated

in a rubber seal, which puts less stress on the windshield and makes it easier to replace at less cost. An optional one-piece windshield is available.

COLLAPSIBLE MIRRORS: Collapsible mirrors fold to eliminate

door sheet metal damage in tight jobsite conditions. Heated, lighted and motorized mirrors are available.

EASY CAB ENTRY: Sculpted self-cleaning steps and a full-size

externally-mounted grab bar provide an extra measure of safety getting in and out of the cab.

UNDER CAB MOUNTED COMPONENTS: The air tanks and battery

box are neatly mounted under the cab, and a full selection of aluminum

™

or steel fuel tanks are available to ﬁt your needs. When Pinnacle outﬁtted with fuel-tank fairings, all components are not only protected, but the side fairings work with the bumper to keep air ﬂowing smoothly along the length of the tractor to boost fuel economy.

“D” SHAPED FUEL TANK: Pinnacle is available with this unique tank

design that holds more fuel in the same space.

CAB AIR SPRINGS: Drivers can work more comfortably thanks to

large, outboard-mounted air springs that provide cushioning, stability and reduced vibration.

HOOD SAFETY LATCH: The hood safety latch engages automatically and

keeps the hood up, even in the windiest conditions. Disengage the latch by simply ﬂipping it up before closing the hood.

LARGE PEEP WINDOW: The large peep window in the passenger door

and visibility doors provide exceptional views, and the quick release mechanism allows easy access for cleaning.

SUN VISOR: External stainless steel or painted sun visors are available.

AIR INTAKES: Pinnacle features optional bright ﬁnish air intake vents.

SMARTWAY® CERTIFIED: We can build any Pinnacle Axle Back

SmartWay Certiﬁed to reduce fuel consumption and lower emissions of greenhouse gases. To meet the EPA’s requirements, trucks are equipped with full roof and fuel tank fairings, side-extenders and an aerodynamic front bumper to reduce drag and improve fuel economy by as much as 30 percent. This eco-friendly tractor rides on low-rolling resistance tires and uses the Idle-Free “Key-Off” HVAC System.

A WELL-DESIGNED DASH IS WITHIN REACH

Sitting in the driver’s seat of the Pinnacle™ is a lot like sitting in a cockpit. The dash wraps around so all switches and controls are close to the driver. There’s no stretching, so there’s less fatigue. Lighting controls can be reached from the ground to facilitate pre-trip inspections. The standard instrument cluster has been enhanced to include integrated gauge warning lamps, an engine oil temperature gauge, a digital voltmeter and a water-in-fuel indicator. A large, easy-to-read, standard driver display features an odometer, maintenance indicator, hour meter, Sweet Spot indicator and an ambient temperature gauge, to name a few.

STEERING COLUMN: The steering column can be adjusted

to an inﬁnite number of positions for maximum comfort, increased belly room and improved visibility of all gauges by simply pressing the quick-release foot pedal.
