2007 Mack Truck Maintenance and Lubrication Manual

The MACK Preventive Maintenance and Lubrication program outlined in this manual is designed to ensure a long and productive life from your truck. The program is divided into four maintenance schedules, each addressing items which require periodic inspections to ensure efficient, reliable and trouble-free operation. To allow flexibility in developing a maintenance routine suitable to your operating requirements, maintenance intervals in this manual are arranged in miles/kilometers, hours or days of operation. Maintenance instructions, specifications and capacities are outlined for quick and easy reference. The service manager at your MACK distributor will be happy to assist in customizing a maintenance program tailored to your operating requirements.

Following the MACK Preventive Maintenance Program is highly recommended to all operators of MACK vehicles because it is the key to lower operating costs both in time and money. The bottom line to a well-run maintenance program is less downtime and increased profitability.

The Diesel Particulate Filter takes the place of the standard muffler. Soot and other particulate matter is collected by a filter inside the unit where it is eventually oxidized using a regeneration process that is either Passive/Active (catalyzed DPF) or Active (non-catalyzed DPF). With the passive/active regeneration process, soot is collected in the filter and oxidized as the vehicle is in operation. An oxidation catalyst raises the exhaust temperature to approximately 260°C (500°F), the temperature at which the chemical reaction takes place to oxidize the soot. When soot loading in the filter reaches a point where it can no longer be oxidized passively, fuel is injected into the system to raise the temperature inside the filter to approximately 625°C (1157°F), the temperature at which active regeneration takes place.

Certain chassis vocations may require more frequent service intervals. When developing a maintenance program, review chassis operating conditions and adjust the service intervals as required. At each maintenance and lubrication interval, look at the condition of chassis lubrication points, condition of components, etc., and adjust your service intervals accordingly. Using a lubricant analysis program performed by a reputable laboratory is the most effective method of determining lubricant change intervals. Alter the maintenance program to meet your needs, but never exceed MACK recommended intervals.

Explanations of maintenance items for noise emission-related components are outlined in “CHASSIS INSPECTION” on page 36, along with schedules at which each item must be serviced. Noise emission-related maintenance items are noted as such for easy reference. The Preventive Maintenance Schedule charts outline the MACK recommended time or mileage intervals between service schedules.

Check operation of engine alarm(s) and shutdown system. The alarms should operate when the key switch is turned ON, before the engine is started, and should shut off when oil pressure, air pressure, etc., reach operating range. The electronic malfunction lamp should turn off approximately two seconds after the engine starts. If the alarms fail to function in this test or other malfunctions are noted, repair as necessary.
