This is an ORIGINAL 5 volume set of International Harvester Navistar "Technical Information for Professional Service Techs" Manual set (January 2003-January 2004 printing).  This manual set has super illustrations as well as having in-depth technical tips and service information for these classic IH Navistar heavy trucks (very in-depth, please see pics). This was information provided to the certified Navistar technician with info not found in the actual service books.  The condition of their covers is very good with light wear, but have NO tears or tatters. The splines are tight and intact with NO loose or missing pages. This manual set contains several hundred pages that are clean and in very good shape as well. Manual set is in VERY GOOD++ overall condition. Buyer agrees to pay $FREE for S & H. Thanks for viewing.............Triple K
