Truckmanuals.com has been working with the Caterpillar print facility since 1999, ensuring the correct factory service information is available to fleets, municipalities, water districts, independent service facilities & more. We at Truckmanuals.com have always felt strongly that it is critical that the industry mechanics be supplied with the correct torque specifications, dimensions & procedures, electronic diagnostic information be made available. The changes in the trucking industry over the decades have made it critical to “do the job once, do the job right”.
Procedures that may have been acceptable years ago would now likely cause rapid failures in a truck engine if they were used on present day engines & drivetrains.
