Daimler Trucks North America LLC distributes the following major service publications in paper and electronic (via ServicePro ® ) formats. Workshop/Service Manual Workshop/service manuals contain service and repair information for all vehicle systems and components, except for major components such as engines, trans- missions, and rear axles. For service and repair information of major components, refer to the OEM’s website. A listing of many OEM websites can be found in Section 00.02 . Each workshop/service manual section is divided into subjects that can include general information, principles of operation, removal, disassembly, assembly, installation, and specifications. Maintenance Manual Maintenance manuals contain routine maintenance procedures and intervals for vehicle components and systems. They have information such as lubrication procedures and tables, fluid replacement procedures, fluid capacities, specifications, and procedures for adjustments and for checking the tightness of fasteners. Maintenance manuals do not contain detailed repair or service information. Driver’s/Operator’s Manual Driver’s/operator’s manuals contain information needed to enhance the driver’s understanding of how to operate and care for the vehicle and its components. Each manual contains a chapter that covers pre-trip and post-trip inspections, and daily, weekly, and monthly maintenance of vehicle components. Driver’s/ operator’s manuals do not contain detailed repair or service information. Service Bulletins Service bulletins provide the latest service tips, field repairs, product improve- ments, and related information. Some service bulletins are updates to information in the workshop/service manual. These bulletins take precedence over workshop/service manual information, until the latter is updated; at that time, the bulletin is usually canceled. The service bulletins manual is available only to dealers. When doing service work on a vehicle system or part, check for a valid service bulletin for the latest information on the subject. IMPORTANT: Before using a particular service bulletin, check the current service bulletin validity list to be sure the bulletin is valid. Parts Technical Bulletins Parts technical bulletins provide information on parts. These bulletins contain lists of parts and BOMs needed to do replacement and upgrade procedures. Web-based repair, service, and parts documentation can be accessed using the following applications on the AccessFreightliner.com website. ServicePro ServicePro ® provides Web-based access to the most up-to-date versions of the publications listed above. In addition, the Service Solutions feature provides di- agnostic assistance with Symptoms Search, by connecting to a large knowledge base gathered from technicians and service personnel. Search results for both documents and service solutions can be narrowed by initially entering vehicle identification data.

Warranty-related service information available on the AccessFreightliner.com website includes the following documentation. Recall Campaigns Recall campaigns cover situations that involve service work or replacement of parts in connection with a recall notice. These campaigns pertain to matters of vehicle safety. All recall campaigns are distributed to dealers; customers receive notices that apply to their vehicles. Field Service Campaigns Field service campaigns are concerned with non-safety-related service work or replacement of parts. All field service campaigns are distributed to dealers; customers receive notices that apply to their vehicles.

See ever, the engine and some items attached to the cab use metric fasteners (diameter and pitch are measured in millimeters). Most threaded fasteners used on the vehicle that are 1/2-inch diameter or larger are plain hex-type fasteners (non-flanged); all metric fasteners are non- flanged. Special hardened flatwashers are used under the bolt head, and between the part being attached and the hexnut, to distribute the load, and to prevent localized overstressing of the parts. The washers are cadmium- or zinc-plated, and have a hardness rating of 38 to 45 HRC. Some fasteners smaller than 1/2-inch diameter are flanged fasteners, which have integral flanges that fit against the parts being fastened. The flanges elimi- nate the need for washers. NOTE: The standard fasteners used to as- semble the vehicle frame and to attach components to the vehicle frame are threaded lock- bolts (Spin Hucks). These fasteners are covered in Fasteners with U.S. customary threads are divided into grades established by the Society of Automotive Engineers (S.A.E.) or the International Fastener Insti- tute (I.f.I.). The fastener grades indicate the relative strength of the fastener; the higher the number (or letter), the stronger the fastener. Bolt (capscrew) grades can be identified by the number and pattern of radial lines forged on the bolt head. See Hexnut (and locknut) grades can be identified by the number and pattern of lines and dots on various surfaces of the nut. See used on the vehicle are grades 5, 8, and 8.2. Match- ing grades of hexnuts are always used: grade 5 or grade B hexnuts are used with grade 5 bolts; grade 8, grade C, or grade G (flanged) hexnuts are used with grade 8 or 8.2 bolts. Fasteners with metric threads are divided into classes adopted by the American National Standards Institute (ANSI). The higher the class number, the stronger the fastener. Bolt classes can be identified by the numbers forged on the head of the bolt. See Fig. 4. by the marks or numbers on various surfaces of the Fig. 1, Fastener Size and Thread Identification Section 31.00. Hexnut (and locknut) classes can be identified Fig. 1. Fig. 2. Fig. 3.

Federal Motor Vehicle Safety Standard 115 specifies that all vehicles sold in the U.S. be assigned a 17- character Vehicle Identification Number (VIN). Using a combination of letters and numerals, the VIN de- fines the manufacturer, model, and major characteris- tics of the vehicle. See Table 1 for the character positions of a typical Freightliner VIN, 1FUPABAV11PA12345. The VIN can be found on the Vehicle Specification Decal (see the vehicle driver’s manual for decal location), and the last six digits (designating the chassis serial number) are stamped into the metal frame. Each product line has its own model list; that is, positions 5 and 6 are product-specific. For example, the code AB in positions 5 and 6 for a Freightliner vehicle indicates an FLD112 conventional truck. Code AB in the same position for a FCCC chassis vehicle represents an MB45 chassis. For all vehicles, a check digit (9th character) is deter- mined by assignment of weighted values to the other 16 characters. These weighted values are processed through a series of equations designed to check validity of the VIN and to detect VIN alteration. NOTE: Always specify the VIN when ordering parts.
