The Remanufacturing Process
Every engine undergoes a comprehensive remanufacturing process designed to restore durability, reliability, and performance.
Complete Cleaning and Preparation
The rebuilding process begins with complete engine disassembly.
Cast iron components are hot tank cleaned while aluminum components undergo thermal cleaning procedures to remove carbon deposits, sludge, and contaminants.
This creates a clean foundation for rebuilding.
Advanced Inspection Procedures
Every major component undergoes extensive inspection before assembly.
Magnaflux testing is used to identify microscopic cracks, hidden defects, and structural imperfections that could affect long-term reliability.
Visual inspections are also performed throughout the rebuilding process.
Precision Machining and New Components
Critical engine surfaces are CNC machined to restore factory tolerances and sealing integrity.
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 where required
These upgrades help restore factory-level reliability while supporting long-term durability.
SIM Testing and Final Validation
Following assembly, every engine undergoes comprehensive SIM testing.
Testing procedures include:
- Oil system pressurization
- Cooling system pressurization
- Compression verification
- Internal sealing inspection
- Build quality validation
The crankshaft is rotated at high RPM under simulated operating conditions to verify engine integrity before shipment.
