front.fr5 Page x Friday, March 17, 2006 11:04 AM CHANGES FROM THE EXISTING E7 MANUAL The ENGINE ASSEMBLY section includes step- by-step procedures for reassembling the engine. This helps to ensure proper installation and longer service life. Mack Trucks, Inc. has made many major improvements to this E7 Service Manual, with changes to both content and organization. The specifications have been revised to reflect changes and improvements in E7 engines. The SETUP AND ADJUSTMENTS section has the latest setup information, complete with charts showing necessary data for adjusting all E7 engine models. Engines perform best and conserve fuel most efficiently when adjusted properly.
All specifications and torque values are given in English and metric measurements. Torque values are also included in the text, eliminating the need to refer to the Fits and Limits chart each time a specified torque value is required. The Special Tools list has been revised to include new special tools. Warnings, cautions, notes and service hints help the technician service the engine safely and efficiently. Two additional sections are included as guides for removing and reinstalling the engine. Both sections are generic in nature. E7 engine installation procedures vary from one vehicle style to another.
These procedures are intended as a checklist to remind the technician of all necessary tasks. The ENGINE DISASSEMBLY section shows how to remove components in an order that requires the least amount of handling. It includes brief component descriptions and information needed to properly service that component. While troubleshooting procedures are similar for most diesel engines, this manual includes only those that pertain to the E7 engine. The TROUBLESHOOTING section contains questions to help the technician consider all possible problem sources. The BENCH PROCEDURES section guides the technician in disassembly, cleaning, inspection and assembly of each component.
It also helps in determining if the part is serviceable or should be replaced. This section alerts the user to component upgrades and helps the technician to decide whether to use the latest available parts or reinstall existing parts. Precise descriptions aid in component identification. This service manual has been revised to include all applicable active service bulletins and service letters since publication of the earlier E7 Service Manual (October 1992). Page x ABOUT THIS MANUAL
