Diesel Dictionary 

Our industry uses a lot of acronyms and industry jargon. Our team has built a module that is on both Diesel Parts & Diesel Repair that is free. Users can search by word or acronym to see definitions to obtain a better understanding to ensure the repair is done right!


Are you going to use a cheater bar on those budds on that cornbinder? Or have you checked the TDC on that Cummins ISX2350? Maybe to test that engine we should run it at WOT?

If you have no idea what we are talking about, don’t feel bad. If it is one thing our industry is great at, it is creating acronyms and industry jargon. These acronyms are commonly used in repair information including wiring diagrams, remove & replace instructions, recalls, and other technical documents. For example, if you aren’t sure what TDC means, or what a BAP sensor is, Diesel Dictionary is your solution.

Marketing materials from manufacturers and dealers are no different. You’ll see words such as B50, Tier 4, aftercooler, and VGT commonly used.

The Diesel Dictionary is your free tool to help you gain a better understanding of the world of commercial trucks. So next time someone mentions they operate a wiggle wagon or asks you to take a look at the pintle hook, you now have a quick and easy way to see what they are actually talking about.
