Rebuild Steps

Every MOOG D664-4707 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

NC Servo Technology operates our 13-stand test facility, including setups for proportional and servo valves. Every valve goes through performance and leak testing using standard test fluids to match your operational needs. Our pre-shipment testing verifies consistent performance.
