The Remanufacturing Process

Every remanufactured engine undergoes a comprehensive rebuilding process designed to restore performance, durability, and reliability.

Complete Cleaning and Preparation

The process begins with complete engine disassembly.

Engine components are carefully cleaned using specialized procedures including hot tank cleaning for cast iron components and thermal cleaning for aluminum parts. These processes remove contaminants, carbon deposits, and accumulated debris.

This ensures a clean foundation for rebuilding.

Advanced Inspection Procedures

Every major component undergoes extensive inspection.

Magnaflux testing is used to identify microscopic cracks, structural imperfections, and hidden defects that could affect long-term reliability.

Visual inspections are also performed throughout the rebuilding process to ensure quality standards are maintained.

Precision Machining and New Components

Critical surfaces are CNC machined to restore factory tolerances and sealing surfaces.

New components installed during assembly include:

• New pistons
• New piston rings
• New bearings
• New lifters
• New oil pump
• New gaskets
• New Viton™ valve seals
• New freeze plugs
• New galley plugs
• New timing chain and tensioners where applicable
• New timing belt and tensioners where applicable
• New timing-driven water pump when required

These new components help restore engine performance and improve long-term durability.

SIM Testing and Final Validation

Following assembly, every engine undergoes SIM testing.

Testing procedures include:

• Cooling system pressurization
• Oil system pressurization
• Compression verification
• Internal sealing inspection
• Build quality validation

The crankshaft is rotated at high RPM under simulated operating conditions to verify performance and reliability before shipment.
