What it is

You find used, reconditioned or remanufactured diesel engines from salvage yards, rebuilders and fleet sell-offs. You list them online, handle the sale and arrange freight to the buyer, often without holding much stock yourself.

Your first three steps

  1. Pick a niche, such as one or two engine families for pickups or medium-duty trucks, and contact several suppliers for wholesale prices and warranty terms
  2. Set up a simple website or marketplace listings with clear photos, engine serial numbers, mileage and condition notes
  3. Sell your first few engines to local repair shops and fleets, and use freight quotes to price shipping accurately
Who pays

Truck and pickup owners, independent repair shops, small fleets, farms and equipment owners who need a replacement engine.

How it makes money

You earn the margin between what you pay your supplier and your selling price. You can also charge for freight handling, core deposits and optional warranty add-ons.

Skills that help
  • Basic diesel engine knowledge (makes, models, common engine families)
  • Sales and clear communication with buyers
  • Organizing orders, freight and paperwork
Watch out for
  • Emissions rules: check EPA requirements and, if you sell in California or other CARB states, which engines can legally be installed in which vehicles
  • Check with your state about whether selling used parts needs a dealer, dismantler or resale license, and register for sales tax and a resale certificate if required
  • Verify engine serial numbers and the supplier's history to avoid stolen or mislabeled engines
  • Heavy freight costs, damage in transit and returns can wipe out your margin, so agree warranty and return terms in writing
  • General liability insurance and a clear written warranty policy
  • Check home occupation, HOA or lease rules if you store engines or parts at home
