How This Remanufactured Engine Is Prepared
A remanufactured engine is more than a used engine assembly.
The remanufacturing process involves disassembly, cleaning,
inspection, machining, component replacement and final testing
to prepare the engine for its intended application.
Deep Cleaning
The engine is completely disassembled before the remanufacturing
process begins. Cast-iron components are hot tanked, while
aluminum components are thermally cleaned where applicable.
Thorough cleaning helps prepare individual components for
detailed inspection and machining.
Inspection and Crack Detection
Engine components are visually inspected throughout the process.
Applicable metal components are also checked using magnetic-particle
inspection to help identify microscopic cracks and fissures that
could affect long-term engine performance.
Machining and Replacement Components
Required machining is performed during the rebuilding process,
including CNC machining of deck surfaces. Depending on the engine
assembly, new components may include bearings, pistons, rings,
lifters, oil pump, gaskets, Viton valve seals, freeze plugs and
galley plugs.
The timing system is also addressed during the remanufacturing
process. Depending on the application, this can include a new
timing chain with tensioners or a new timing belt with tensioner.
Engines using a timing-driven water pump may also receive a new
water pump.
Final SIM Testing
After reassembly, the engine undergoes SIM testing. The cooling
and oil systems are pressurized and the crankshaft is spun at
high RPM to help verify compression, system operation and
overall build quality.
