Welcome to Truckmanuals.com

We offer factory service manuals for heavy-duty diesel trucks.  These manuals are designed for professional technicians by companies such as Caterpillar, Cummins, Navistar (International Harvester), Detroit Diesel, Allison and more.  These manuals more than pay for themselves in a short period of time by having the correct information when you need it.  Having the correct manual the first time saves your time & money.  This allows your business to reduce diagnostic / repair time & increase cash flow.  Why have a "budget" manual that may not have all the information you need?  Or gives erroneous information?  Using a factory service manual is simply the most cost efficient way to do business.

Most orders will ship within 24 - 48 hours.  If there is any additional delay we will contact you.

You may contact us if you have any questions.
