Repair, Rebuild or Reman: Which One Do You Need?

	Repair	Rebuild	Reman Exchange
What it is	We fix the specific problem with your unit	We disassemble your unit, replace worn and damaged parts, and return it to OEM spec	You buy a unit we have already rebuilt and in stock, and send yours back as a core
Best when	One known failure, need it back fast	Significant hours or unknown internal condition	Downtime is the priority and your model is in an exchange program
Warranty	Not a warranty item if a separate issue appears later	Warranty on the rebuilt unit	Warranty included
Your unit	You get yours back	You get yours back	You get a different rebuilt unit, yours goes back as a core

Repair

A repair addresses a specific known problem. We diagnose the failure, fix that issue, and get you back in service, either in the field with a road service technician or in-shop with our diagnostic and test equipment. Because a repair addresses the reported fault rather than the whole unit, other wear items may still be present, so a repair does not carry the warranty coverage a full rebuild does.

Rebuild

A rebuild returns your own unit to OEM specification. We disassemble it completely, inspect every component, and replace anything excessively worn or damaged with genuine OEM parts. The unit is reassembled, tested on our stands, painted and crated. Rebuilt units carry a warranty. This is the right choice for most equipment, since reman exchange is only available on specific models that are part of a manufacturer program.

Reman

Reman exchange is the fastest path back to production. We stock common high-volume units in a rebuilt, ready-to-install state at Madison and other branches. You buy the rebuilt unit plus a core charge, we ship it, and when you return your old unit in acceptable condition we credit the core charge back. Exchange programs only work when cores come back, so core return terms are part of every exchange order.
