The Mindset of Remanufacturing

Remanufacturing is not just a set of processes. It is a mindset. Five principles distinguish true remanufacturing from lesser imitations. 

Principle 1: Assume Nothing 

The repair technician assumes a component is good until proven otherwise. The remanufacturer assumes a component is bad until proven good.

Principle 2: Wear Items Are Always Replaced 

Certain components have finite lifespans: bearings, seals, gaskets, brushes, filters, belts. Even if they appear functional, they have consumed part of their design life.

Principle 3: Restore, Don't Just Replace (When Economical) 

Some components (housings, shafts, blocks) are expensive to replace but can be restored to original tolerances through machining, grinding, thermal spray coating, or other processes.

Principle 4: Test to New-Product Standards 

A remanufactured product must perform identically to a new product under the same test conditions.

Principle 5: Warranty Parity 

A remanufactured product without a new-product warranty is not truly remanufactured. It is something less—rebuilt, reconditioned, or refurbished—regardless of what the marketing says.

Remanufacturing is not equally applicable to all products. It thrives where: 

• The core has high intrinsic value (e.g., cast iron block, precision-ground shaft) 
• Wear items are modular and replaceable 
• The product is designed for disassembly (or can be disassembled with reasonable effort) 
• New replacement cost is high 
• Customers value reliability and warranty
