The Remanufacturing Process

Every HEMI engine undergoes a comprehensive remanufacturing process designed to restore reliability, durability, and performance.

Complete Cleaning and Preparation

The remanufacturing 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. This removes carbon deposits, contaminants, and accumulated debris from years of service.

Advanced Inspection Procedures

Quality begins with thorough inspection.

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

Each component also undergoes detailed visual inspection before being approved for reuse.

Precision Machining and New Components

Critical engine 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 upgrades help ensure long-term reliability and consistent performance.

SIM Testing and Final Validation

Every engine undergoes SIM testing after assembly.

Testing procedures include:

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

The crankshaft is rotated at high RPM to simulate operating conditions and verify engine integrity before shipment.
