Rather than purchasing the entire Caterpillar service manual (which take up a lot of space), why not get just the info you need?  This engine overhaul manual set takes very little space & includes the factory information you need.  Saves both money and space. has worked with the Caterpillar for many years, striving to ensure the correct factory service information is available to:

  • Fleets
  • Municipalities
  • Federal, state & local entities
  • Independent service facilities

At we’ve always felt that it’s critical that the mechanics be supplied with the correct factory information.

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 on newer trucks.  Remember, not all service manuals are created equal.  Buy factory, buy the best.

The customer has two great advantages when dealing with

  1. Factory printed manuals
  2. Most orders are shipped within 24 hours
