DIESEL PARTS / BUYING GUIDES

# New vs Rebuilt Diesel Components

Compare new, refurbished, rebuilt and remanufactured component decisions before purchasing.

## New, Rebuilt or Refurbished: What Changes?

New, rebuilt, remanufactured, refurbished, reconditioned, used and exchange are different commercial descriptions. They may carry different core obligations, testing evidence, warranty conditions and return rules. Our team can help you compare condition, testing information, warranty details and any core-exchange terms for the exact component you need. For an existing pump or injector, inspection and evaluation may clarify whether repair or exchange is appropriate. Do not send an old unit until DCT confirms receiving instructions.

## Information That Helps Us Find a Match

Share the full stamped manufacturer number, the equipment and engine details, quantity, desired condition and a clear photograph if necessary. If the original component is damaged or missing, provide any documented cross-reference or serial details for review.
